Fact Sheet #39B: Prevailing Wages and Commensurate Wages under Section 

14(c) of the Fair Labor Standards Act (FLSA) 

This Fact Sheet provides general information concerning the establishment of prevailing wages and 

commensurate wages as they pertain to the employment of workers with disabilities at special minimum wages. 

Please read Fact Sheet No. 39, The Employment of Workers with Disabilities at Special Minimum Wages, 

for a general overview of the provisions of Section 14(c). Please consult the Regulations, 29 CFR Part 525, 

Employment of Workers with Disabilities under Special Certificates, for detailed information concerning 

Section 14(c). These Regulations may be found at http://www.dol.gov/dol/allcfr/ESA/Title_29/Part_525/toc.htm. 

What is a commensurate wage? 

A commensurate wage is a special minimum wage paid to a worker with a disability that is based on his or her 

individual productivity (no matter how limited) in proportion to the productivity of experienced workers who do 

not have disabilities performing essentially the same type, quality, and quantity of work in the vicinity where 

the worker with a disability is employed. The commensurate wage in the context of work subject to Section 

14(c) is always less than the applicable minimum wage required by section 6(a) of the FLSA, or where 

applicable, the prevailing wage required by a McNamara-O'Hara Service Contract Act (SCA) Wage 

Determination. 

How does an employer determine the proper commensurate wage for each employee with a disability? 

In order to determine the commensurate wage, the employer must first examine the work to be performed by the 

employee with a disability, and through the use of an accepted work measurement technique, develop a 

"standard" that accurately measures the quality and quantity of that same work when performed by workers 

who do not have disabilities. Work measurement methods, such as time studies, Modular Arrangement of 

Predetermined Time Standards (MODAPTS), and Methods-Time Measurement, are used by employers to 

determine the length of time it should take a worker who does not have a disability to perform an operation, or 

element of an operation. The commensurate rate is then determined by comparing the performance of the 

worker with a disability against that "standard." In very simple terms, if the worker with a disability is 60% as 

productive when performing a particular job as is the experienced worker who does not have a disability 

performing the exact same job, the commensurate wage for that worker with a disability would be at least 60% 

of the prevailing wage (the wage rate paid to the experienced worker who does not have a disability). 

What is a prevailing wage under Section 14(c)? 

The prevailing wage for a particular job performed by a worker with a disability who receives a special 

minimum wage is the wage paid experienced workers who do not have disabilities performing essentially the 

same type of work in the vicinity. An employer paying a special minimum wage must be able to demonstrate 

that the prevailing wage rate used to determine a commensurate wage was objectively determined. Normally, 

prevailing wage rates are based on the results of surveys conducted by the employer. The prevailing wage is not 

an entry-level wage or a training wage, but the wage rate paid experienced employees after completion of any 

training or probationary periods. An experienced worker is one who has learned the basic elements or 

requirements of the work to be performed, ordinarily by completion of a probationary or training period. 

Typically, such a worker will have received at least one pay raise after successful completion of the 

probationary or training period. The prevailing wage may not be lower than the applicable statutory minimum 

wage as established by section 6(a)(1) of the FLSA or, where applicable, a higher state minimum wage. 
 

 

 

 

 

 

 

 

 

How does an employer conduct a prevailing wage survey under Section 14(c)? 

To conduct a survey, the employer must obtain wage information for each job classification being performed by 

workers to be paid a special minimum wage. A brief job description should be prepared that defines the specific 

job duties, responsibilities and tasks; identifies the types of equipment and supplies used to perform the tasks; 

lists the types of skills, education or experience levels required; and indicates the location, and days and times 

of the week the work will be performed. 

The employer should obtain wage data from comparable businesses in the vicinity that primarily employ 

workers who do not have disabilities performing the same work and utilizing similar methods and equipment as 

used by the worker with a disability. A comparable business is one that either employs a similar number of 

employees or competes for contracts of a similar size and nature. The appropriate size of the sample - the 

number of firms surveyed - will depend on the number of firms doing similar work in the vicinity, but normally 

should include no less than three. The prevailing wage information should be solicited, preferably in writing, 

and the employer conducting the survey should record the following information regarding each prevailing 

wage survey contact: 

(1) date of contact; 

(2) name, address and phone number of firm contacted; 

(3) individuals contacted within each firm and the title of each individual; 

(4) the wage rate information provided and the basis for concluding that each rate submitted was not based 

upon an entry level position; 

(5) a brief description of work for which wage information was collected. 

After contacting a sufficient number of comparable firms, the employer must average the wage information 

provided to determine the prevailing wage for a particular job. The employer may use either a weighted or 

simple average so long as he or she is consistent. See the following example:

 Weighted Average: $1,080.49 ÷ 141 employees = $7.66305 or $7.67* 

Straight Average: $23.37 ÷ 3 employers = $7.79 

*Note that in this example the weighted average yields a prevailing wage rate of $7.66305, but the 

employer rounded it up to $7.67 per hour. If the employer rounded to $7.66, he or she would be 

establishing a prevailing wage rate that is less than the true prevailing wage rate (less by $0.00305 

per hour). The Wage and Hour Division will not normally question computations that are carried 

out to the fifth decimal point and then rounded up to four decimal places. The employer could, of 

course, round up (but not merely round off) sooner. For example, .04974 should be rounded to 

.0498 or .05. 
 

Must all employers of workers with disabilities paid special minimum wages conduct prevailing wage 

surveys? 

No. If an employer's workforce consists primarily of workers who do not have disabilities, the wage rate that the 

employer pays to his or her experienced workers who do not have disabilities who perform similar work may be 

adopted as the prevailing wage. Similarly, if an agency or community rehabilitation program places a worker 

with a disability on the premises of such an employer, the wage paid the employer's experienced workers who 

do not have disabilities performing similar work may be used as the prevailing wage. 

In addition, the prevailing wage for workers with disabilities performing as service employees on contracts 

subject to the Service Contract Act would be the wage listed for the classification of work being performed on 

the Department of Labor Wage Determination included in the contract (if any). If a Wage Determination is 

included in the contract, all service employees (included those paid special minimum wages) must also receive 

the full fringe benefits listed on the Wage Determination. Please see Fact Sheet 39F, The Payment of Special 

Minimum Wages to Workers with Disabilities Who Are Employed on Federal Service Contracts Subject to the 

McNamara-O'Hara Service Contract Act, for more information concerning the Service Contract Act. 

Finally, if the employer has a subcontract to perform a job in essentially the same way and with the same type 

of equipment as the prime contractor, the employer may use as the prevailing wage the wage rate the prime 

contractor pays to his or her experienced workers. 

How often must an employer conduct a prevailing wage survey? 

The prevailing wage survey must be conducted prior to paying a special minimum wage. It then must be 

reviewed and updated at least once a year - more frequently when a change in the prevailing wage has most 

likely occurred, such as when the FLSA minimum wage or a higher state minimum wage has been increased. 

A word about the rules of ROUNDING when computing special minimum wages. 

Section 14(c) requires that workers with disabilities for the work performed who receive special minimum 

wages must receive at least the commensurate wage for all hours worked. An employer who follows the normal 

business rules of rounding - rounding "up" only when the last decimal point is a five or higher - may actually be 

underpaying workers with disabilities. Although the underpayment per unit produced would be very small, the 

eventual back wage liability could be quite large considering the number of units that could be produced over an 

extended period of time by a number of different workers. This can be avoided by carrying computations out to 

the fifth decimal and then always rounding up to the fourth place. The Wage and Hour Division will accept the 

practice of carrying out computations to the fifth decimal point and then rounding up to the fourth decimal place 

as compliance when computing special minimum wages due workers with disabilities under Section 14(c). Of 

course, an employer may round "up" sooner than the fifth decimal point.
