The Physical Education Teacher Attitudes Toward Fitness Test Scale (PETAFTS) produces reliable and valid scores. There were 4 stages and 4 sets of participants in the development of the PETAFTS. First, the domains of attitude were defined and cognitive and affective components were developed, organized, and validated. In the second stage, 134 full-time physical education teachers participated in a pilot study and PETAFTS was revised based on the information obtained. In the third stage, 28 teacher educators served on an expert panel and organized the items into domain areas. In the final stage, 322 physical education teachers from 10 states tested the revised PETAFTS. Based on the results, the PETAFTS was shortened by deleting and combining some of the items in subdomains; this resulted in a 16-item final version that, according to the indices, generates reliable and valid scores.
