FOREWORD

The methodology presented in this document consists of

procedures for examining the capabilities of laboratories to

perform physical testing on industrialized building. Tests

required in ANSI A119. 1-1969 and in the Laboratory Evaluation

and Accreditation Program (LEAP) "Criteria for Testing Laboratories"* form the basis for the examination of technical

resources. Therefore, this report on Methodology is a companion

document to the LEAP report on "Criteria for Testing Laboratories."

A Laboratory Examining Agency is envisioned, acting at the

convenience of the State Accrediting Authorities, within a relationship described herein under sections entitled "This is

LEAP" and "General Information for Laboratories Applying for

Accreditation Under the LEAP Program for Industrialized Building

Including Mobile Homes". Both of these descriptions form a part of the Advance Information Package which is included under

the chapter "Initial Communications".

INTRODUCTION

This document deals with the collection of technical information about laboratories. A two step process* is presented:

(1) study of advance information supplied by the laboratory and

(2) on-site examination of laboratory resources. Figure 1 illustrates the sequence of events from initial communications to

final report.

Initial Communications -- Briefly, the flow of events

shown in Figure 1 begins with the Initial Communications Phase

when a laboratory applies to a specific state for accreditation

under that state's LEAP regulations. The state then notifies the

proposed Laboratory Examining Agency to initiate an examination

of the laboratory's technical capabilities. The Laboratory

Examining Agency does this by sending an Advance Information

Package to the laboratory. The package includes orientation

information, the Criteria for Testing Laboratories and an examination application form. After reviewing this material,

the laboratory completes the application form and returns it

to the Laboratory Examining Agency.

Advance Preparation -- Upon receipt of the laboratory

application, the Laboratory Examining Agency then notifies the

state that an application for examination has been received.

This event starts the Advance Preparation Phase. The state

proceeds with its own appraisal of the laboratories business

operations and the Laboratory Examining Agency initiates a thorough study of the technical information furnished on the

application.

After the examining agency has completed the study of the

technical information and determined that there are no critical

deficiencies in the laboratory resources or gaps of information

in the application, and has approved the proposed set up for

the test demonstration, an on-site visit is scheduled.

On- Site Visit -- During the On-Site Visit an examiner

collects information in two ways. First he completes a questionnaire, obtaining the needed information through visual

inspection and by direct questioning of the laboratory staff.

Secondly, the examiner observes the demonstration of an actual

test as proposed by the laboratory. The examiner may also

photograph non-proprietary facilities and test set ups . At

the close of the on-site visit, highlights of the collected

information are reviewed with a person designated by the

1 ab oratory

*Possible approach that the states may use to facilitate

reciprocity among themselves.

Repo rt -- The Laboratory Examining Agency prepares a technical report consisting of a compilation and summary of

information gathered during the Advance Preparation and On-Site

Visit Phases. Copies are mailed to the candidate laboratory

and the State Accredi tat i ng Authority. If, within a reasonable

period of time,* the laboratory seeks accreditation in other

states, a copy of the technical report will be furnished to

those states in lieu of repeating the laboratory examination.

The following is a more detailed outline of procedures

used to collect the technical information -- a part of the

total information to be evaluated by the state as a basis for

granting accreditation to a testing laboratory. Included are

certain procedures and recommended forms felt to be expedient

and necessary to the work of the proposed Laboratory Examining

Agency and the State Accrediting Authori ty (s ) .

*To be determined by the National Conference of States on Building Codes and Standards.

3
INITIAL COMMUNICATIONS

The objectives of the Initial Communications Phase are

to convey to interested laboratories the objectives and

requirements of the Laboratory Evaluation and Accreditation

Program, and to receive from candidate laboratories preliminary

information on technical resources.

The initial communication phase begins when a laboratory,

that wishes to be accredited notifies a particular state that

it is as capable of performing physical testing on mobile homes

and other industrialized structures. Under authority established

by state regulations for the Laboratory Evaluation and Accreditation

Program, the State Accrediting Authority then requests that

the Laboratory Examining Agency start the technical examination

process .

This process is initiated by sending four documents (see

page 4) to the laboratory. These four documents make up the

Advance Information Package. One of the four, the Criteria

for Testing Laboratories, is published under separate cover.

Suggested models for the other three items and for a sample

cover letter are presented in this section.

One of the documents included in the Advance Information

Package is the "Application Form for Laboratory Applying to

State for Accreditation Under LEAP Program." Submittal of the

completed application form to the Laboratory Examining Agency

marks the end of the Initial Communications Phase.

THIS IS LEAP

FOREWORD *

The sample brochure "This Is LEAP" was prepared by the

Center for Building Technology, National Bureau of Standards,

for the National Conference of States on Building Codes and

Standards (NCSBCS). The subject of the brochure is that the

state is answering inquiries from interested parties regarding a recently passed law es i^abl i shi ng a state Laboratory

Evaluation and Accreditation Program (LEAP).

The states have expressed urgent need for development of

a program providing for state recognition of institutions that

are competent to evaluate industrialized buildings and/or

building components. The program should also provide the states

with a basis for informal reciprocity of laboratory accreditation findings and the results of laboratory evaluations of

bui 1 di ng systems

To allow the earliest possible initiation of the process,

NCSBCS has suggested that a pilot program be initiated using

the North Carolina regulations for industrialized buildings,

which adopts by reference the only existing national consensus

standard for a complete building system, ANSI A119. 1-1969

Standard for Mobile Homes. These regulations allow A119.1 to

be used as a reference for building modular dwelling units and

other factory built structures, as well as mobile homes.

Using the pilot program as a foundation, the brochure "This

Is LEAP" explains how the laboratory accreditation program works.

The brochure references the A119.1 standard. While the content

of A119.1 applies specifically to mobile homes, the program

outlined in "This Is LEAP" describes procedures for accrediting laboratories that can later be applied to all industrialized building systems by making appropriate changes in the

requirements and criteria. A119.1 is being used only to build

a system for evaluating laboratories. No implied endorsement

of the A119. 1-1969 Standard is intended by NBS.

THIS IS LEAP

INTRODUCTION

Building technology is changing rapidly and we are witnessing increasing industrialized production of a wide

range of complex construction components and assemblies.

Designers and builders want to take advantage of these technical and economic advances and this demands more technically

difficult evaluations by cc^c officials. Such evaluations

would also entail trips to distant factories and the need for

regular follow-up inspections.

Because industrialized building systems may be manufactured outside the state borders and often times will

involve innovative processes about which little field experience

has been gained, the State of * has established

regulations for recognizing competent, bui 1 di ng- eva 1 uat i on

institutions. Interested laboratories may apply for accreditation

under the * regulations entitled "Laboratory Evaluation

and Accreditation Program" (LEAP).

WHAT DOES IT ALL MEAN ?

FOR THE LABORATORIES -- Accreditation by the State of

* means that the work of a laboratory will be

accepted by * , whether or not the housing

system producer or the laboratory itself is located within

the borders of this state.

FOR THE HOUSING SYSTEM PRODUCER -- The LEAP Program is

designed to assure equitable evaluation of industrialized

housing products or techniques, particularly those of an innovative nature.

FOR THE CITIZEN -- The LEAP Program is one of the key

elements needed to assure that building components, fabricated

and assembled in factories, will be subjected to inspections

equivalent to those given to on-site constructions.

FOR THE STATE -- The LEAP Program enables the state to

summon the best combination of government and privately owned

technical resources to the task of evaluating the design and

quality of prototype dwelling units, and of certifying conformance of production units with approved prototypes by

providing follow-up, compliance assurance services. LEAP also

opens the door for competent, tax-supported, building department laboratories, to request accreditation by * . The credibility so established is intended to be the basis for

informal interstate reciprocity of dwelling certification

programs, with all the attendant economies that this entails.

LABORATORY ACCREDITATION

The accreditation "team" lineup and relationships are

illustrated in Figure 2. A summary of the functions and

responsibilities of each member of the team follows.

Authority for the LEAP Program stems from state regulations entitled "Laboratory Evaluation and Accreditation

Program." Basic elements of the regulations include:

0 Establishment of a State Authority for Accrediting

Laboratori es

.

0 Adoption of a nationally recognized consensus

dwel 1 i ng standard

.

0 Establishment of a State Appeals Board.

The accrediting authority is that state agency which is

charged by LEAP Regulations with implementing the program.

Functions of the accrediting authority include:

0 Answers requests for information about laboratory

accredi tat i on

.

0 Notifies the Laboratory Evaluation Agency (LEA) to

initiate evaluation of the laboratory's technical

resources

.

0 Investigates non-technical aspects of an applicant

laboratory's operations, such as finance, corporate

relationships, credit, insurance, business reputation.

0 Accepts a report from LEA covering the laboratory's

technical resources and capability to do the required

work

.

11
0 Grants or denies initial accreditation based on results of it's own investigation of laboratory

operations and LEA's examination of laboratory

technical capability.

0 Withdraws accreditation, for cause, based on follow-up reports on laboratory operations or

technical performance, or the results of the regular, periodic re-examinations specified in LEAP

Guidelines.

Information gathered by the accrediting agency and LEA

is considered proprietary and will be handled as provided by

the LEAP Guidelines.

LEA is the Laboratory Examining Agency responsible for

determining the capability of applicant laboratories to perform tests, evaluation, and/or compliance assurance required by

the housing standard. The agency is composed of laboratory examiners skilled in the respective disciplines, and experts

responsible for recommending to a consensus body those

changes needed to upgrade the laboratory-evaluation procedure

standard.

The laboratory-evaluation-procedure standard provides

the criteria and methodology for LEA's examination of a laboratory. Cost of the examination is borne by the applicant laboratory. The examination itself is composed of three

pa rts :

0 Review of advance information on technical resources

furnished by the laboratory to LEA.

0 On-site examination of technical resources, including

demonstrations by laboratory personnel of set-up and

procedures for conducting required tests, analyses,

and/or quality assurance tasks.

0 Submission of a final report to the State Accrediting

Authori ty

While the Laboratory Examining Agency operates at the

convenience of the state, the agency is staffed and supervised

by an independent, nationally recognized organization and

12
functions neither as an arm of state government nor as a commercial or tax supported testing, evaluation or compliance

assurance laboratory (See definition in "Laboratory" below).

LABORATORY

TESTING LAB

EVALUATION AGENCY

COMPLIANCE ASSURANCE AGENCY

As illustrated in the heading, the term "Laboratory" is

used loosely here to describe any one or a combination of

three types of organizations applying for accreditation under

* 's LEAP Program for industrialized building

including mobile homes. Distinctions between the terms Test

Laboratory, Evaluation Agency and Compliance Assurance Agency

are given in the definitions of the laboratory evaluation procedure standard. A laboratory having the appropriate competence may apply for accreditation in any or all of the above

basic functions. However, the laboratory will be examined

for competence using separate criteria for each of the

functional areas requested.

Interested Test Laboratories and Evaluation Agencies must

apply for accreditation in one or more of the following

building system disciplines:

0 Electrical

0 Fire Safety

0 Heating, Ventilating and Air Conditioning (HVAC)

0 PI umb i n

g

0 Structural '

Continuation of the accredited status of a laboratory is

contingent on successful re-examinations which are periodically

conducted in accordance with LEAP Guidelines.

* Insert name of particular state

13
This consensus standard is the criteria used by the

Laboratory Examining Agency in evaluating the capability of

a particular facility. LEA examines the laboratory's capability to test, evaluate and/or perform follow-up compliance

assurance work with reference to the nationally accepted

consensus dwelling standard adopted by the LEAP Guidelines

As discussed under the "Laboratory" block in page 13, the

criteria provides that a particular facility may request

accreditation to perform services covering one or all of the

disciplines mentioned therein.

If the laboratory seeking accreditation believes that

improper interpretation or application of the LEAP Guidelines

by the accrediting authority has caused the denial of accreditation or the withdrawal of previous accreditation, the, 1 aboratory

has recourse. The LEAP Guidelines include an appeals procedures

and the establishment of an objective, third party, appeals

board.

GENERAL INFORMATION FOR LABORATORIES APPLYING FOR

ACCREDITATION UNDER THE LEAP PROGRAM FOR

INDUSTRIALIZED BUILDING INCLUDING MOBILE HOMES

It is the purpose of this information sheet to assist

you in interpreting the application requirements for technical resource examination under the LEAP* program. The discussion that follows pertains to these three documents:

0 Form for making application to (State

)

for

accreditation under the LEAP Program

0 ANSI A119. 1-1969 Edition

0 Criteria for Testing Laboratories

A thorough understanding of A119. 1-1969 and the LEAP

Criteria will be necessary in order to successfully complete

the application.

You have indicated interest in accreditation as a Testing Laboratory to perform testing services on industrialized

building.

The distinction between the terms Testing Laboratory,

Evaluation Agency and Compliance Assurance Agency is given in the

Definitions, Criteria Part 1. Note that a laboratory having

appropriate competence may apply for accreditation to perform

any or all of the above three basic functions. The laboratory

will be examined for competence in each area requested.

As a Testing Laboratory you may apply for accreditation

in one or more of the following building system disciplines:

0 Electrical Testing

0 Fire Safety Testing

0 Heating, Ventilating and Air Conditioning

(HVAC) Testing

0 Plumbing Testing

0 Structural Testing

* Laboratory Evaluation and Accreditation Program

15
There is space on the application form to indicate those

building system disciplines for which you wish to make application. If you select more than one discipline you will need

to fill out a separate application form for each.

The Laboratory Examining Agency will collect data on your laboratory's technical resources and technical competence. The Laboratory Examining Agency will not evaluate

this data but will submit it to the State Accrediting Authority

for evaluation along with certain other information gathered by

the state.

The technical resource examination conducted by the

Laboratory Examining Agency consists of two parts:

0 Written and graphic information supplied to this

office by your laboratory, as indicated on the

application f orm

0 An on-site visit by an examiner to inspect laboratory facilities, to review test procedures and

policies and to observe test demonstrations by

your laboratory personnel in accordance with instructions on the application form.

The application form includes several questions regarding

the willingness of the laboratory to allow the examiner to do

his job in a specific way. Unwillingness of the laboratory to

cooperate with this aspect of the evaluation may result in

rejection of the application.

In order to qualify as a testing laboratory it will be

necessary to show i n - h o u s e capability to perform all of the

tests required under the appropriate discipline in A119.1 and

the Criteria. The ability of your laboratory to witness or

evaluate tests performed by others or to actually perform

tests using outside equipment, instrumentation and facilities,

will not in general, qualify you as a testing laboratory under

this program.

The State Accrediting Authority may, under certain circumstances, permit a small part of the total testing to be

subcontracted. Conditions for granting such exceptions will

include, but not be limited to the following:

a) The percentage of the total testing capability to

be subcontracted must be less than approximately

*Percentage figure to be established by NCSBCS.

16
b) The prime laboratory assumes full responsibility

for work done by the subcontractor.

c) The subcontractor is examined by the Laboratory Examining Agency, for the subcontracted portion only.

d) A full description of the tests to be subcontracted

and a copy of the contractural provisions are furnished by the candidate prime laboratory and approved

by the State Accrediting Authority.

e) The State Accrediting Authority finds the competence

of the subcontractor to be acceptable. Note: The

subcontractor will not be independently accredited.

f) Once accredited, the prime laboratory agrees to

maintain the approved contract in force with the

subcontractor until the prime laboratory requests

and receives approval for different subcontract

arrangements from the State Accrediting Authority.

Failure to comply with this requirement may subject

the prime laboratory to immediate revocation of

acc-redi tat i on .

A schedule for the on-site laboratory examination will

be proposed by the Laboratory Examining Agency, subject to

approval by the laboratory, after the completed applications

have been received and accepted.

I ADVANCE PREPARATION

Associated with the Advance Preparation Phase are two

basic objectives for the examiner:

0 Review the advance information and compare it to

the minimum requirements of the Criteria.

0 Organize the information furnished and relate it

to information to be sought during the on-site visit.

The Advance Preparation Phase begins when the Laboratory

Examining Agency notifies the state than an application for

examination has been received and that, at first glance, it

appears complete. The state then initiates it own review of

laboratory business operations while the Laboratory Examining

Agency proceeds with a thorough review of the technical information provided by the candidate laboratory.

Resumes of laboratory personnel are reviewed by the

Laboratory Examining Agency; specific individuals are keyed

to appropriate parts of the questionnaire to be used for

reference during the on-site examination. Pertinent education,

training and experiences are tabulated for future inclusion in

the technical report.

Lists of the laboratory's instrumentation and test equipment, and sketches and photographs of building facilities,

test area and special test equipment are reviewed by the

examiner. Wnere possible, the review is augmented by study

of manufacturer's operating instructions and maintenance

handbooks. The examiner utilizes this information both to

acquaint himself with the laboratory's resources in advance

of the on-site visit and to check that mi ni mum requirements

of the Criteria are satisfied.

If critical deficiencies in laboratory resources or gaps

in information are evident, these are resolved with the laboratory before scheduling the on-site visit. Failure to

correct critical deficiencies (reference minimum requirements

specified in the Criteria) within * months will result in

termination of the examination process, with notification to

this effect being sent to the laboratory, through the state.

The laboratory may submit a new request for accreditation, to

the state, no sooner than * months after the date of

termi na t i on .

*To be determined by the National Conference of States on Building Codes and Standards.
In addition to the general approach just outlined, two

detailed procedures are given in this section to facilitate

the examiner's preparation for the on-site visit. These are

31^
INTERVIEW GUIDELINES

The following guidelines pertaining to the interview are

included for use by the examiner in preparing for the on-site

examination of a laboratory. Special note should be made of

the attitude of cooperation that these guidelines stress. The

examiner should be aware that everything he says and does

reflects on the total evaluation program. He should always

conduct himself in a manner that will be a credit to himself

and the program.

It is advisable to confer with the laboratory or section

manager prior to approaching the supervisors and test operators. The manager should be given a brief overview of the

examination program and his cooperation should be solicited.

With the support or acquiescence of the manager, direct

employee participation should then be sought.

The processes of fact gathering are probably fraught with

more pitfalls than any other area pertaining to laboratory

evaluation. The people supervising and performing the tests

represent a prime source of information concerning the laboratory. The process of accumulating facts regarding the overall

laboratory (as a system) may carry the impl Icatiors , to the

person supplying information, of dissatisfaction with current

operations. Thus, this prime source of information may become

resentful, fearful, and uncooperative. This potential problem

can be minimized by using a tactful approach and by verification of data against alternative sources.

Getting along with people is extremely important in

survey initiation and data gathering; however, it cannot be

reduced to a set of rules. A friendly and pleasant manner

coupled with a genuine interest in the other person constitutes the right combination.

Interviews with personnel should be researched and planned

in advance. Organizational structure and position descriptions

covering the area of the Interview provide excellent preliminary

data. In addition, previous examination reports, other data

furnished on the application form, the Methodology procedures,

and the Criteria for Testing Laboratories, provide valuable

preliminary information. The examiner shall become thoroughly

acquainted with this material.

From this advance information an interview outline will be

developed. Armed with background knowledge of the laboratory

gained from the advance Information and an interview outline,

the examiner is now ready to keep the interview appointment.

Be prompt for the appointment. If a change in schedule must

be made, make it as far in advance of the date set as possible.

35
Last minute cancellations or changes are discourteous and

irritating.

Never argue! If an argument develops^, change the subject

to areas of known interest and try to avoid an early return

to the subject of contention.

Take notes. They help organize the material and clarify

thinking. The individual being Interviewed is likely to be

more cooperative if his ideas are important enough to be

recorded. Be a good listener firsts and a good talker second.

You learn more by listening than talking.

Conclude the interview promptly when the necessary information has been acquired. Strive to keep the interview within

the planned time span.

During preliminary study of the advance information, an

attempt at blocking segments of time to be spent with each

area should be made. As experience 1s gained, more precise

allocations of time will be possible. However, it should

always be uppermost in the examiner's mind that there are

other interviews to be conducted and more questions to be

answered. The examiner should avoid falling into the trap of

being willing to listen beyond the established time of the

interview. This creates the impression that the examiner has

nothing else to do and eventually may lead to the examiner

being blamed for wasting time.

Information obtained from the interview must be verified

where possible. This can be accomplished by comparing the

information obtained in various interviews. Where possible,

discrepancies should be resolved by observation of actual

operations or by returning to the individual at variance.

Existing laboratory records and documents may save the

examiner a great amount of time and avoid the recording of

facts already documented. Procedures, position descriptions,

laboratory manuals, etc., all represent valuable sources of

information. These, however, should be verified by observation, as they may or may not reflect current conditions in

the laboratory. Recent figures may be available in final

reports, control records, tabulated listings, etc.

The examiner should avoid making any judgmental remarks,

i.e. "good show," "poor procedure," etc.

After preparation, advance study and practice, the

examiner will still find situations that call for clear

thinking and tact. As experience is gained, the accomplished

interviewer will find his own means of establishing a successful interview technique that will enable him to handle the

unusual situation.

TYPICAL OPENING REMARKS

"Mr. . "

"My name is

' and I represent the

laboratory examining agency. I have your application for

examination as a ( d i s c i p 1 i n e 1 testing laboratory for ( s tate

.

As you know, the purpose of this examination is to

inspect your test facilities and test reporting system and

to assess the capability of your laboratory personnel. To

achieve this objective, questions will be asked of various

persons in your laboratory and I will witness the demonstration tests agreed upon earlier. I will also ask for copies

of certain reports and procedures.

The collected information will be reported to you and

to ( s tate

, and will be evaluated by (state

. Notice of your

accreditation status will be sent to you by (state

.

At the close of my examination today, I would like to

meet with you, or with a person you designate, to review the

information collected. Do you have any questions?

If you have no further questions, I would appreciate a short tour of the laboratory and introductions (*) to the

supervisory and test personnel (hand over prepared list of

names). These are the people I will be interviewing."

*Cons i derati on should be given to asking the manager to call

a meeting of his supervisors so that the examiner can explai-i

the purpose of the examination and the manager can request

supervisory cooperation. Time will be saved and the work can

start earlier in the day if this interview can be conducted

the afternoon before the scheduled examination.

38
CLOSING INTERVIEW

A closing interview shall be held with the manager or

head of the laboratory or with such persons as he may designate. The examiner will review pertinent aspects of the

information gathered and provide the manager an opportunity

to make additions or clarifications. Record all additional

information in its appropriate location on the questionnaire.

Do not delete or remove any information obtained previously.

After a brief review, thank the manager or head of the

laboratory for his time. Do not leave notes, reports, copies

of reports, scratch paper, questionnaire or any personal items

behind.

39
QUESTIONNAIRE FORMAT AND RATING SYSTEM

INTRODUCTION

The questionnaire is an organized series of questions

arranged by building system discipline, to be employed by the

examiner in collecting information during the on-site visit.

Two types of questions are ^'eluded; those in which the information is obtained through the personal observations of

the examiner and those in which directed verbal questions or

written technician quizzes are answered by laboratory personnel.

The examiner will record the answers for both sources of information. The scope and wording of the questions are designed to minimize subjective judgments on the part of the examiner.

Appendix A "Evaluation Guidelines" provides assistance

to the accrediting authority in evaluating the reported answers to the questionnaire.

ORGANIZATION

There is a questionnaire for each of the five building

system disciplines used in the Criteria for Testing Laboratori es . These are

0 Structures

0 Heating, Ventilating and Air Conditioning (HVAC)

0 Fire Safety

0 Electrical

0 Plumbing

The questions under each discipline are divided into

those related to General Testing Information and those associated with the Test Demonstration, as outlined below.

( DISCIPLINE ) GENERAL TESTING INFORMATION

Information is to be collected by visual inspection and by questions directed to laboratory

personnel , in the areas of:

0 Equipment - Test machines and apparatus

other than instruments

ko
0 Instrumentation - Measuring instruments

0 Facilities - Buildings and building fixtures

associated with the test area and engineering

of f i ce

0 Personnel - Laboratory management, supervisory and test personnel.

TEST DEMONSTRATION

The examiner witnesses test demonstrations and

answers questions based on his observations. The nature

of the tests is established during the Advance Preparation Phase. If an actual industrialized structure is

unavailable, the tests may be conducted on a building

subsystem mock-up.

FORMAT

The following example illustrates the format for the

questions.

Keyword

(Storage) 1. Is there storage space available, when

(2) (0) not in use?

(2)

Wei gh

(0)

Identifier Question

In the example, a keyword identifying the substance of

the question is provided for the benefit of the examiner.

Below the keyword, the first symbol in parenthesis reveals

whether or not the objective of the question is a "must" (M)

or a "want" (reflected by a numerical weighting.)* The

second symbol in parenthesis designates the person to whom

question is directed. The personnel code employed is as

f ol 1 ows :

the

(M) Manager - Person in charge of laboratory

operations

(S) Supervisor - Person in charge of the test(s)

under consideration

(0) Operator - Person conducting the test

*Reference "Rating System" below.

hi
(E) Examiner - Person conducting the laboratory

exami nat i on

RATING SYSTEM

The intent of the rating system is to provide a means of

summarizing the body of examination data, in a manner which

can ultimately lead to a f 1

: re of merit. This figure of

merit can be related to a minimum rating established by the

accrediting authority as commensurate with satisfactory technical competence.

Each question is classified either as a "must" or a "want." li" a question related directly to a mandatory requirement of the Criteria, then it is a "must" (M) . Musts represent Go, No-go criteria and thus they are not numerically

weighted. If the objective of the question is a desirable,

but not mandatory, characteristic or attribute of the laboratory, then it is a "want" question. "Wants" are expressed

in terms of relative desirability and thus they are numerically

weighted.

WEIGHTING SCALE

Weight is the value attached to the subject matter

of the question.

The first step in the weighting process is to establish the position of each "want" objective relative

to the desired goal of the laboratory's competence to

perform physical testing. This is done by giving it a numerical weight of importance.

The particular scale used is arbitrary. However,

it does allow for discrimination in recording the importance of each objective. Table 1 illustrates the

weighting scale used in the Methodology Questionnaire.

SCORING SCALE

The score is the degree of completeness with which

the laboratory meets the objectives underlying the question or the directed visual observation.

Only the answers to "want" questions are scored.

If the laboratory fails to meet the requirements of a "must," the accrediting authority will generally consider

this limitation a barrier to accreditation.

TABLE 1 WEIGHTING SCALE

CATEGORY WEIGHT SIGNI FICANCE

Must A mandatory attribute

Want 5 Very high want, just

short of must

4 High want

3 Medi um want

2 Modest want

1 Low want

When assigning a numerical score of 0 to 5 to the

"want "- answers , the Laboratory Examining Agency must

employ its judgment and experience since there are only

two clear cut cases of scoring as illustrated in Table 2.

FIGURE OF MERIT

Equation 1 illustrates a suggested figure of merit

that the accrediting authority may use.

E (W. X S.)

i =1

= Figure of Merit Equation 1 nZ X W. X 5

i=l

Where: n = total number of Want questions in

questionnaire

W^ = total weight of a given question

S^. = score of that answer

5 = maximum score for answer

I = sum of

The f i rst case i s i = 1

The procedure is:

1. Multiply the weighted questions by their score.

2. Add all the resulting products.

3. Obtain the maximum weighted score points

available.

4. Divide (3) into (2) and multiply by 100.

This value is the percentage rating or Figure of

Merit for major functions of the laboratory or for the

laboratory as a whole. The State Accrediting Authority

may wish to further investigate problem areas revealed by

the final report. As experience is gained, it is envisioned that the accumulated Figures of Merit for a number

of laboratories will be reviewed by the various State

Accrediting authorities to establish minimum acceptable

values.

hh
TECHNICIAN QUIZZES

Certain of the following questionnaires include attachments

incorporating questions and related photographs under the

general heading of Technician Quizzes. These abbreviated

quizzes are intended to fill only a supplementary role along

with other personnel evaluation procedures, including review

of resumes, direct interviews, examination of training programs and observation of nerformance during demonstration

tes ts .The specific questions included in the quizzes are intended only to be suggestive and should be more fully developed as examining experience is gained. It is envisioned that

advance information about the subject matter to be covered by

the quizzes, would be given to the candidate laboratories.

REPORT

Every laboratory examination shall be covered by a written

report. The report and attachments shall present an organized

summary of information collected from the application for examination and from the on-site visit. The basic purpose of the

report is to provide technical information to the state accrediting authority in support of its evaluation of the laboratory's

capabilities.

The report shall be reviewed and signed by the examiner

and by the manager of the Laboratory Examining Agency, before

being transmitted.

Copies of the report shall be furnished to the candidate

laboratory and the cognizant state. At the request of the

laboratory, limited copies of the report will also be furnished

to other governmental or industrial organizations. The content

of the technical report shall in no way be used for advertising

purpos es .

If, within a reasonable period of time*, the laboratory

seeks accreditation in other states, a copy of the technical

report will be furnished to those states in lieu of repeating

the laboratory examination.

*A regular cycle of periodic, updating examinations is envisioned in "This Is LEAP," page 10. A suggested "reasonable

period of time" for utilizing the results of a previous examination for additional applications to other states would be

up to one-half of the period of the normal, re- exa mi na t i on cycl e

SI CONVERSION UNITS

In view of present accepted practice in this country in

this technological area, common U.S. units of measurement have

been used throughout this paper. In recognition of the position

of the USA as a signatory to the General Conference on Weights

and Measures, which gave official status to the metric SI systems of units in 1960, we assist readers interested in making

use of the coherent system of SI units, by giving conversion

factors applicable to U.S. units used in this report.
