This study examines the convergent validity and divergent validity of the Student Engagement in School Success Skills (SESSS) survey. The SESSS is easy to administer (it takes fewer than 15 minutes to complete) and is used in schools to provide educators with useful information about students' use of skills and strategies related to school success. A total of 4,342 fifth graders completed the SESSS; the Motivated Strategies for Learning Questionnaire (MSLQ) Cognitive Strategy Use, Self-Regulation, Self-Efficacy and Test Anxiety subscales; and the Self-Efficacy for Self-Regulated Learning (SESRL). The three subscales of the SESSS (Self-Direction of Learning, Support of Classmates' Learning and Self-Regulation of Arousal) correlated highly with the MSLQ Cognitive Strategy Use and Self-Regulation subscales, moderately correlated with the Self-Efficacy subscale and the SESRL, and did not correlate with the MSLQ Test Anxiety subscale. Future research is needed to use the SESSS subscales as discriminable dimensions.
