Attitude toward STEM influences on learning outcomes. The research purpose was to validate of attitude towars STEM. Sample are 393 students (Grade 7-Grade 12) for validating the Attitude toward STEM Self-Inventory (ASTEM). Totally 21 ASTEM items consist of 6 items of Mathematics Attitude, 6 items of Sciences Attitude, 6 items of Engineer/Technology Attitude, and 6 items of 21 st Century Skill Attitude. Second-order confirmatory factor analysis was used to confirm the construct validity. The results confirmed that the construct validity of these test an excellent fit. The results show that: the fitness index of validating the ASTEM were as follow: x 2 statistic is 254.650 (degrees of freedom = 220, p = 0.054), and the x 2 /df ratio having a value of 1.158 indicates a good fit. The comparative fit index (CFI) is 0.988, and Tucker-Lewis coefficient (TLI) is 0.984, Root mean square error approximation (RMSEA) is 0.020, Standardized Root Mean Residual (SRMR) is 0.045.
