MEMORANDUM No. 170
MEMORANDUM FOR ALL CONTRACTING AGENCIES OF THE FEDERAL
GOVERNMENT AND THE DISTRICT OF COLUMBIA
FROM: CHARLES E. PUGH
Acting Administrator, Wage and Hour Division
SUBJECT: Publication of the Fourth Edition of the
Service Contract Act Directory of Occupations
January 1993
The fourth edition of the Service Contract Act Directory of
Occupations is now available and being sold on a subscription
basis for twenty-six dollars ($26.00). The subscription price
includes the initial volume plus two annual supplements, to be
delivered over the subsequent two years. The new edition may be
ordered by calling the Superintendent of Documents at (202) 783-
3238 or by writing to the superintendent of Documents, U.S.
Government Printing Office, Washington, D.C. 20402. Refer to
stock number 929-041-00000-3 when placing your order.
The Directory provides a common vocabulary for occupations most
often included in Service Contract Act wage determinations. It
is used by procurement staff as a key time-saver in developing
Service Contract Act wage determination requests. Wage and Hour
staff utilize the Directory in developing and enforcing wage
determinations. All new and revised wage determinations will
reflect content of the fourth edition beginning March 1, 1993.
It was intended that the Directory continue to be produced in
loose-leaf form, to facilitate use of annual Directory
supplements. Since copies of the fourth edition have been
inadvertently bound, subscribers will receive an entire loose-
leaf version with the first annual supplement.
For the first time, the fourth edition of the Directory provides
Federal Grade Equivalencies for most of the occupations included.
These will help to standardize the development of Service
Contract Act wage determinations and assist interested-parties in
preparing and evaluating conformance requests. The fourth


















 -2-
edition also provides appendices to assist readers in following
changes from previous editions to the current version.
Inquiries regarding the SCA Directory fourth edition may be-made
by telephone to Mr. Ron Karp at 202-219-7531. Also-, Mr. Karp
should be informed of any Directory problems and suggested
changes or additions. Send such information to his attention at:
