RECOMMENDED METHODS OF EVALUATION: The table of specifications below
identifies the number of enabling objectives/key indicators per cognitive domain level
of learning (Knowledge, Comprehension, Application) per module. The instructor
should develop 1-3 test questions per Knowledge Level of Learning, 2-4 test
questions per Comprehension Level of Learning, and 5-6 questions per Application
Level Learning. The instructor should use the following test item types for each level
of learning:
Knowledge: Alternative Response test items (true/false or yes/no)
Comprehension: Multiple Choice
Application: Multiple Choice, Short Answer Exercises
The instructor should ensure each student meets the performance and standards
published in each criterion objective. See FAA AC 147-3 Certification And Operation
Of Aviation Maintenance Technician Schools Appendix 1for evaluation instrument
guidance and development.

Glossary of Terms
A teaching-learning plan which includes student centered
instructional objectives, outlined content, instructional and
evaluation strategies, and other relevant information
needed to guide the development and/or revision of
learning experiences such that students achieve stated
educational outcomes.
Entry-level skills students must acquire during enrollment in
the course.
The overall goal of the course of instruction stated in broad
terms.
The terminal outcome each student is required to meet.
Criterion objectives are directly related to industry
competencies. There will be one or more criterion
objectives published for each industry competency.
The required knowledge and/or skill each student must
acquire in order to have the best chance of achieving the
stated performance in the criterion objective.
Used to ensure adequate sampling of student knowledge as
specified by the enabling and criterion objectives.
The domain of learning typified by thinking and focused on
the development of intellectual capabilities.
The domain of learning typified by performing or doing and
focused on the development of motor skills.
Section Explanation
A broad description of key elements in a given course.
Used to identify courses taught in multiple disciplines.
Course required in conjunction to the specified course often
in the form of a lab
