There are four phases to the Deerfield High School (Chicago, Illinois) sex-fair performance evaluation system: (1) a point system allowing students to control 50 percent of their grades through participation and attendance; (2) an ongoing evaluation procedure concerned with determining the contributions of various units of instruction (all curriculum offerings are evaluated in terms of their contributions to various forms of fitness); (3) the use of the AAHPERD (American Alliance for Health, Physical Education, Recreation, and Dance) Physical Fitness Test and the Health Related Fitness Test; and (4) skill testing as a means of assessing personal performance and maintaining a high level of student participation--standard tests and individual teacher developed tests are used. Deerfield High School's assessment program places all athletic activities in the physical education program in five major physical fitness categories: (1) cardiovascular; (2) flexibility; (3) kinesthetics; (4) motor ability; and (5) strength/power. Categories involving lifetime sports and general fitness are also included. Physical education activities are examined for their contribution to student improvement in these areas. Appendixes include a report on the assessment testing program, a summary of the assessment evaluation program, a discussion of a projected testing program, and a report on assessment testing results for specific athletic programs. Also included is a list of tests used for measuring fitness in each of the five major categories. (JD)
