Purpose: This study explored how preservice physical education teachers (PPETs) perceive health-related fitness testing (HRFT) administered in a self-testing format with the aim to enhance their HRFT learning and better prepare them for future HRFT implementation. Methods: The study utilized a constructive phenomenological research design. A total of 11 PPETs participated in the study. Data were collected through a focus group interview, individual interviews, observation and field notes, and written assignments. Two researchers analyzed the data in NVivo 12. Results: Three findings were concluded from the data. First, the administration of self-testing engaged PPETs in active learning of HRFT. Second, PPETs reported positive attitudes toward self-testing when their needs for competence, autonomy, and relatedness were satisfied. Lastly, PPETs identified challenges and proposed suggestions for completing and administrating HRFT. Conclusions: Self-testing may be used as an alternative approach to preparing PPETs for HRFT. More research is needed to examine the effectiveness and reliability of self-testing in educational settings.
