Relationships have been found between teacher efficacy and many teaching and learning variables, but few researchers have examined teaching efficacy in physical education. The instrument reported here, the Physical Education Teaching Efficacy Scale, was developed based on the teaching efficacy literature, existing scales, and National Association for Sport and Physical Education's Teacher Education Standards. Students attending 11 institutions who are majoring in regular and alternate physical education teacher education and who are at different stages of preparation (N = 592) completed the initial survey. Exploratory, followed by confirmatory, factor analysis resulted in a 35-item, 7-factor scale. Factors were Content Knowledge, which were activities one might teach; Applying Scientific Knowledge in Teaching, which reflected academic content; Accommodating Skill Differences; Teaching Students with Special Needs; Instruction, which included management, motivation, and instruction; Using Technology; and Assessment. Results support that the Physical Education Teaching Efficacy Scale addresses many aspects of teaching physical education and meets research criteria for validity and reliability.
