Student Curriculum
The student curriculum shall consist of (1) set of 2 Learning Activity Packets with 14 skills covering reading prints, selecting wiring sizes, installing industrial wiring, wire splicing, wire bundling, wire labeling, and layout.

The student curriculum shall be designed in a skill-based format that focuses on teaching industry- relevant tasks. The objectives shall be accomplished by organizing the learning material into a series of learning activity packets, which are further subdivided into three or more segments per packet.  All learning material needed shall be contained in the packets including text material, laboratory equipment activities, and multimedia directions.  No external text sources shall be required.  The specific cognitive skills taught by each text passage shall be identified next to the passage.  Each lab activity shall be identified by the industrial task taught.  All activities shall be highly detailed with step-by-step instructions to facilitate a self-directed learning environment.  A combination of step-by-step enabling activities and creative, problem-solving activities shall be provided.  A self-review of five to ten questions shall be provided after each segment. The curriculum must be capable of both self-directed and instructor directed study. All activities must correlate directly to the hardware supplied, with detailed illustrations and diagrams.

Teacher’s Assessment/ Portfolio Guides
A teacher’s guide shall be provided. It shall contain student data sheets, data sheet solutions, self-review answers, quizzes, quiz answers, student skill record sheets, and authentic assessment. A quiz shall be provided for each packet.  A question shall be provided in each quiz for each cognitive objective taught.  All tasks listed in the packet shall be listed on personalized student record sheets. The Instructor’s Package shall include directions for authentic skill assessment.
