Abstract:
The aim of this paper is to examine the relationship between both school environment and peer influences on the
one hand and students’ academic performance on the other hand. The study assessed school environment factors
and peer influences in terms of the level of psychological impact they have on learners. The study was based on
Albert Bandura’s Social Learning Theory, which considers leaning as an interaction between environment,
behaviour, and one’s psychological processes. It was a correlation study carried out in Sabatia District of Vihiga
County in twenty-one public secondary schools. The respondents were selected using simple random sampling
technique. Questionnaires were used to collect data, which were analyzed by multiple regressions. The study
established that school environment and peer influence made significant contribution to the students’ academic
performance. A school, as a learning institution and as a second home for learners, has a strong relationship with
students’ academic performance. The head teacher and the teachers through their specific roles either have
negative or positive influence on students’ academic performance. Therefore, the head teacher and the teachers
should enhance a conducive learning environment in which the learners are free to consult them when in need,
provide adequate learning facilities and arouse interest in the learners to work hard. Peer level factors also have a
relationship with students’ academic performance. It is hoped that the findings of this study will be useful to
teachers, principals and parents to gain more insight into the psychosocial factors that affect students’ academic
performance and therefore help improve their academic performance
