An activity was undertaken to develop written criterion-referenced tests for the forestry component of Applied Principles of Agribusiness and Natural Resources. Intended for tenth grade students who have completed Fundamentals of Agribusiness and Natural Resources Occupations, applied principles were designed to consist of three components, with each component comprising one-third of the school year. The forestry component was designed as a specialized component to be taught together with the common core and one other specialized component. A criterion-referenced test was developed for the forestry component from a list of competencies that was compiled. Project results were a list of specific competencies for the forestry component of Applied Principles of Agribusiness and Natural Resources Occupations and an item bank of multiple choice test items and answer keys for the forestry component. Criteria for selecting items from the item bank for testing purposes were recommended. (Two tables display summary statistics and complete item analyses for each question in the item bank. Appendixes, amounting to approximately two-thirds of the report, contain the list of competencies, test items, and answer keys.) (YLB)
