The following descriptions of the components of the Definition Trailer are in inverse order to their placement in
the trailer.





I. DATE OF LAST UPDATE (DLU)
Listed as the final element in the trailer following the definition, the Date of Last Update indicates the last year
in which material was gathered for that occupation.  A DLU of ``77'' would indicate that the occupation has not
been studied by an analyst since publication of the fourth edition DOT in 1977.

II. SPECIFIC VOCATIONAL PREPARATION (SVP)
Specific Vocational Preparation is defined as the amount of lapsed time required by a typical worker to learn the
techniques, acquire the information, and develop the facility needed for average performance in a specific
job-worker situation.
This training may be acquired in a school, work, military, institutional, or vocational environment.  It does not
include the orientation time required of a fully qualified worker to become accustomed to the special conditions
of any new job. Specific vocational training includes:  vocational education, apprenticeship training, in-plant
training, on-the-job training, and essential experience in other jobs.
Specific vocational training includes training given in any of the following circumstances:
a.   Vocational education (high school; commercial or shop training; technical school; art school; and that
     part of college training which is organized around a specific vocational objective);
b.   Apprenticeship training (for apprenticeable jobs only);
c.   In-plant training (organized classroom study provided by an employer);
d.   On-the-job training (serving as learner or trainee on the job under the instruction of a qualified worker);
e.   Essential experience in other jobs (serving in less responsible jobs which lead to the higher grade job
     or serving in other jobs which qualify).
The following is an explanation of the various levels of specific vocational preparation:
Level     Time
1    Short demonstration only
2    Anything beyond short demonstration up to and including 1 month
3    Over 1 month up to and including 3 months
4    Over 3 months up to and including 6 months
5    Over 6 months up to and including 1 year
6    Over 1 year up to and including 2 years
7    Over 2 years up to and including 4 years
8    Over 4 years up to and including 10 years
