					         README FILE Automotive Technology Revised Statewide Standard

The Automotive Technology Statewide Standard is comprised of the NATEF 2002 Automotive Technology Task
List and the NATEF 2004 General Service Technician Task List with the addition of Duty A - Essential Skills, in
which NATEF assumes students will receive adequate training.

Please go to http://natef.org/program_standards/auto/service_tech.cfm for information about NATEF’s Task List
and Assumptions and certification requirements.

Core Tasks

In the statewide standard, all tasks in Duty Areas A through H7 are marked with an * as suggested core. If you
plan to get General Service Technician certification for your program, all these tasks must be covered.

If your program is NATEF/ASE certified, or you plan to pursue this certification, you can make Duty Areas H
through H7 inactive since these tasks are duplicated in the Automotive Technology Task List (Duty Areas I1
through P6)

All the tasks in the NATEF Task List (Duty Areas I1 through P6) are assigned a Priority designation by NATEF
of P1, P2 or P3. [visit the NATEF website for further details] In the statewide standard these P1-P2-P3
designations appear in brackets at the end of each task.

NATEF does not include performance criteria with the task list. Performance Criteria will be determined by an
Automotive Technology Instructor Workgroup.

The Duty Areas in the Automotive Technology Standard It is suggested that you read the entire task list and
mark the Duties/tasks you do not teach so that they can be made inactive in the SISME database.
