Learners' self-regulation, which includes motivational variables, is influenced by personal variables within learners themselves, as well as by contextual factors. A great deal of research has focused on personal variables in learners that influence their self-regulated behaviours; yet contextual influences that operate outside of formal schooling of township school learners, although generally acknowledged, remain under-researched. The research presented in this paper explored 14 secondary township school teachers' perceptions of the factors that influence learners' motivation to achieve academic success. A better understanding of contextual motivational factors could influence teaching and learning, as well as provide the needed support that ultimately will enhance the academic achievement of South African township school learners. Participants perceived autonomy-supportive, extrinsic motivation, schools as positive learning environments, study and job opportunities, community projects, friends and peers, poverty, and encouragement from the local community as strong sources of motivation.
