Racial-ethnic and low-income youth have differential access to key educational resources that promote learning and college readiness. College readiness programs provide activities, resources, and experiences that support learning. Yet little is known about the influence of adults and peers in shaping students' beliefs and expectations as learners. This study examined the extent to which GEAR UP adolescent self-regulated learning was influenced by perceptions of adult and peer behavioral expectations. Among the 118 adolescent participants, perceived behavioral expectations of a parent or guardian was found to be the strongest determinant of self-regulated learning. Implications and directions for future research are discussed.
