The Standards Self-Efficacy Scale (SSES) was developed to assess 204 pre-service teachers' self-efficacy beliefs to utilize as part of the InTASC professional standards for teachers. Principal component analysis revealed the nuanced factor structure of the SSES to measure standards-based self-efficacy. The SSES was compared to the well-established General Teacher-Efficacy (GTSE) Scale to determine its comparative validity that showed significant correlations with all four factors of GTSE with providing evidence that the SSES effectively measures selfefficacy. Implications for SSES as a valid measure aligned with the InTASC standards allowing for a standards-integrated approach are discussed.
