The "SuccessNavigator"™ assessment is an online, 30 minute self-assessment of psychosocial and study skills designed for students entering postsecondary education. In addition to providing feedback in areas such as classroom and study behaviors, commitment to educational goals, management of academic stress, and connection to social resources, it is also designed to predict a range of early academic outcomes. By indicating students' likely success, advisors, faculty, and staff can target their interactions with students to increase their likelihood of success. This report outlines evidence of reliability, validity, and fairness to demonstrate the appropriateness of SuccessNavigator for these purposes.
