This study was designed to investigate the status of teachers' use of fitness tests in school-based physical education programs. Full-time physical education teachers (N = 325) in 10 states participated. A questionnaire was developed specifically for this study to collect data. Various methods were utilized to lend evidence for the reliability and validity of the items on the questionnaire. Means and standard deviations of continuous variables and Likert-type variables were computed. Frequencies of category variables were calculated and percentages of the frequencies were reported. The results were: (a) most of the teachers used fitness tests with the majority using nationally available fitness tests (among those who implemented the nationally available fitness tests, most utilized the norm-referenced test [i.e., President's Challenge, 1998] and not criterion-referenced tests [i.e., the Fitnessgram, or YMCA Youth Fitness Test Program]), (b) teachers in general implemented different approaches to prepare students for fitness testing and most teachers informed students verbally about the tests in advance, (c) helping students gain awards was the least important purpose for teachers to use fitness tests, and (d) fitness testing was not strongly associated with teachers' fitness/physical activity instruction. The data from the study suggested that fitness testing is merely an isolated part of physical education programs. (Contains 8 tables.)
