DICTIONARY OF OCCUPATIONAL TITLES (4th Ed., Rev. 1991) --
APPENDIX A
APPENDIX A
REVISIONS FROM THE 4TH EDITION DOT
In this revised edition of the Dictionary of Occupational Titles
(DOT), several format and content changes were made in an effort to make this
DOT easier to use.
The most noticeable change in this revised DOT is that a profile has been
appended to each definition. This profile contains the following selected
occupational analysis characteristics: GOE Code; Strength rating; R, M, and L
of GED; and SVP. (A detailed explanation of these characteristics can be
found in Appendix C.) The last item in the trailer, the Date of Last Update
(DLU), is the date of the most recent material gathered in support of that
occupation. The date "1977" indicates that the occupation has not
been studied since the publication of the fourth edition DOT in 1977. This
entry allows the reader to identify the currency of each definition. It also
identifies "new" definitions in the DOT or alerts the reader to
previously published and recently updated definitions.
A new division has been added to the DOT classification structure, Division
03 COMPUTER-RELATED OCCUPATIONS, and under it there have been added five new
Occupational Groups to reflect a reorganization of the DOT taxonomy to bring
all of the computer-related occupations together. The five Occupational
Groups are as follows:
030 OCCUPATIONS IN SYSTEMS ANALYSIS AND PROGRAMMING
031 OCCUPATIONS IN DATA COMMUNICATIONS AND NETWORKS
032 OCCUPATIONS IN COMPUTER SYSTEMS USER SUPPORT
033 OCCUPATIONS IN COMPUTER SYSTEMS TECHNICAL SUPPORT
039 COMPUTER-RELATED OCCUPATIONS, N.E.C.
Additionally, when an updated occupational definition in this DOT contains
a reference to the title of another occupation, the DOT code of the referenced
occupation is listed, following the referenced DOT title. Within the
definitions and the indexes, Undefined Related (UR) titles will now be shown
in initial capital letters instead of all captial letters to avoid confusion
between Base and UR Titles.
Also, additional appendices have been added to the revised DOT. In this
revised DOT, Appendix A is new. Appendix B was the Appendix in the 1977 DOT.
Appendix C, mentioned above, explains the components of the definition
trailer, Appendix D explains how to use the DOT for job placement, and
Appendix E explains how to submit information concerning occupations not found
in the DOT. (Appendix D and Appendix E were sections in the front of the 1977
DOT).
The fourth edition DOT Industry Designations have been revised and reduced
from 220 to 140 Industry Designations to more closely reflect the Standard
Industrial Classification system. And finally, to facilitate its use, the
Alphabetical Index of Occupational Titles appears as the last section in the
DOT.
