Recoamended apecif'ications in connection with the classification of 

civilian positions tor employees performine cryptographic and cryptanalytic work. 

l. The class specifications tor positions as prescribed b7 the 

Personnel Clasa1f'ication Board only cover a f'ew cryptographic duties 

and do not cover cryptanalytic duties whatsoever. In order that this 

of'tice, which has cognizance of personnel performi!Jg such duties for 

the War Department, may have a plan to be guided by, the following 

general specifications are recommended. These recommendations correspond very closely with similar specifications alrea~ provided in the 

Personnel Classification Bo~rd pamphlet. 

·Cryptographic Work 

2. Cryptographic work in government service can be generally divided into two classes: 

la) Those performing straight cryptographic work such as deciphering, decoding, enciphering arid encoding regular 

traffic. This class would also include those connected 

with the au.pervision o'! such 11o1Drk and those who prepare 

or assist in the preparation ot codes and ciphers. 

( b) Tho se who llS rform cryptographic work in connect ion with 

the cryptanalytic activities of a research desk. 

In the latter case the work is similar to, but not identical with, the 

work done by the first class, b~t is easily as important and difficult. 

In the latter class, due to the type of work involved, it will normally 

be essential that the person doi.ng this cryptographic work must also be 

an excellent .typist and be able to follow the work through more than is 

required of those in the !irst class. 

3. The following specific classifications are recommended: 

la) Assistant cryptographic clerk - C.AF-3 - "Under immediate ·' 

or geners..l supervision, to perform cryptographic work commensurate with encoding and decoding telegrams in connection with the cryptanalytical research activity." (~1620-;)1920) 

(b) Cryptographic clerk - C.AF-4 - "Under i:m::1ediate or general 

su.pervision, to perform responsible cryptographic work similar to that or reviewing and revising the encoding and decoding 

of' telegrams, including the classification and certain cryptanalytic steps in code· and cipher research work f'rom a detailed 

outline in connection with the cryptanalytic research activity." (41800-~2100)

(c) Senior c17ptographic clerk - CAF-5 - "Under general supervision, 

to perform difficu.lt and responsible cryptographic work similar 

to preparing or assisting in the preparation ot codes and ciphers 

SllCh as performing independently all the crn>tanal11; ic step a in 

code and cipher research work from a bare outline in connection 

with the cryptanalytic activity." ($2000-32500) 

Cryptanalytic~ 

4. ~ork of this character is not covered in class specifications 

except th~t under the Scientist Gro·w.p the performing of technical work in 

a mathematical acience is covered~ Work of this character is clearly of 

a scientific nature and should be classified as professional and scientific work. 

5. The following specific classifications are recommended: 

(a) Cryptanalyst aid - SP-5 - "This position will be the normal 

starting point of a person ~1th two years college work incl\ldihg c~urses in mathematics or equivalent training, who is 

entered immediately upon a special course of 1n1tr\1Ction for 

work as &. technical aesistant in cryptanalysis. "($1800-$2100) 

(b) Junior cryptanalyst - P-l - "This position will be the normal start~ng point of a person with training equivalent represented 

by that of graduation with a degree from an institu.tion of 

recognized st6ll.ding with major work in mathematics, and with a 

good working knowledge of at least one toreign language, who 

is entered iD1U1ediately upon a special course or instruction 

tor work as a cryptanalyst." l~2000-~2500) 

(c) Assistant cryptanalyst - P-2 - ''To perform under inmediate or 

general s~pervision, independently or with a small number of 

su.bordinates, cryptanalytic work requiring previollS experience 

and training, and, to a limited extent, the exercise or independent judgment." ( ~2600-:~3100) 

(d) Associate cryptanalyst - P-3 - "To perform independently or 

with a small nWlber of trained assistants, under general supervision bu.t with considerable latitude in the exercise of independent judgment, responsible cryptanalytic work requiring extended training and considerable previous experience.'" (:~3200-$3700) 

(e) Crypt&nalyst - ~-4 - ''To perform, under general supervision, 

difficult and responsible work req\liring consider6ble cryptanalytic training and e::i.-perience, and the exercise of independent 

j udgrr.ent • " ( .~3800-:}44<>0)

REF ID:A69340 . 

(t) Senior cryptanalyst - P-5 - "To perform, under general administrative au.pervision, import~nt cryptanalytic work requiring 

extended training and exper~ence, the excercise of independent 

judgment, and the assumption of responsibility for resu.lts; or 

for the administration or a small organization eng~ged in crypta.na.lyt ic work." (~600-·~5200) 

(g) Principal cryptanalyst - P-6 - ''To act as assistr:.nt head of a 

large organization engaged in cryptanalytic work, or to serve 

as a consulting specialist in connection with new machines s.nd 

systems, or to devise new machines or systecs independently." 

( ~~600-36400) 

(h) Head cryptE.nalyst - P-7 - ''To act as administrative head of a 

large orgenization engaged in cryptanalytic work; or to act aa 

professional consultant to a dep6.l'tment head in connection with 

cryptanalytic l'liork." (.)6500~7500) 

6. It must be recognized th~t in work or this chiracter no simil~r 

actiYity exists in civil life, and th~t it will be necessary in the £Overnment service to commence persons, in general, with a college education, in 

this kind of work and eventually train them for this duty.
