The purpose of this study was to examine the factorial validity and reliability of the "Achieving the NASPE Standards Inventory (ANSI)" that assesses pre-service physical education teachers' perceptions of achieving the National Association for Sport and Physical Education (NASPE) beginning teacher standards (2003). Four hundred fifty-two pre-service teachers from 15 Physical Education Teacher Education (PETE) programs voluntarily and anonymously completed the inventory. The hypothesized measurement models were analyzed by means of a confirmatory factor analysis. The Goodness-of-fit statistics indicated that the modified 3-factor model with 38 items represented a best fitting model with the data. The scores generated by the total and the 3 subscales of the 38-item ANSI demonstrated a high level of internal consistency. (Contains 3 tables and 2 figures.)
