Parents’ involvement has always been critical to the performance of students in any given institution of learning. The aim of this study was to assess the effect of parents’ involvement on pupils’ academic performance at Magezi Primary School. For the purpose of this study, the researcher measured parent involvement using three variables, including; Parenting (Do parents provide basic needs and communicate/encourage children on their education?). Facilitating learning at home (Do parents provide an environment and instructional materials to help their children’s learning at home?). Volunteering (Do parents help in improving school infrastructure and participate in decision-making?). The researcher used a crosssectional design and for the purpose of this study, the list was comprised of a population of 143. The sample size was 125 out of 143 determined using tables developed by Krejcie and Morgan (1970) which ensures good decision model. The findings therefore concluded that that volunteering by students significantly influences academic performance, parenting significantly influences academic performance and good learning environment positively influences academic performance. The researcher therefore recommends that Magezi primary school parents should make Learning Environment more comfortable and encourage their children, parents should continue to tell children that studying, reading and revising are not only done while at school.
