The curriculum guide for Vocational Agriculture 4 (Grade 12) contains 27 color-coded units of instruction organized into four sections: farm business management, leadership and careers, plant and soil science, and agricultural mechanics. The instructional units are designed to account for 60% of an instructor's time, the remaining 40% is left to the individual instructor to use with reference to the needs of the local community. For each unit the guide provides: objectives, both terminal covering the unit's subject matter, and specific covering student performance expectations (on white paper); suggested activities fashioned around the specific objectives (on white paper); information sheets containing essential facts necessary for teaching the unit (on green paper); assignment sheets focusing on written skills (on brown paper) with answer sheets (on pink paper); job sheets providing necessary instructions for completing a production job (on blue paper); transparency masters of appropriate charts, pictures, or illustrations (on white paper); and tests for measuring students' accomplishment of specific objectives (on yellow paper) with answer sheets (on pink paper).
