The study specifically examined the relationship between parental influence, home environment, school environment and students’ academic performance in Integrated Science. The study adopted descriptive and ex-post facto research designs. The population for the study comprised of 68 (200 level) Integrated Science students in Ekiti State University, Federal University, Oye-Ekiti, and Bamidele Olumilua University of Education, Science and Technology, Ikere – Ekiti. Total enumeration was used because of the small population size. Environmental Factors Questionnaire (EFQ) and Students’ Performance Inventory were used to collect data for the study. The questionnaire was validated by experts in Tests, Measurement and Evaluation. The reliability of the questionnaire was established using the Test re-test method. Data generated from this study were analysed using descriptive and inferential statistics. The findings of the study revealed that parental influence (r = 0.519, p<0.05), home environment (r = 0.471, p<0.05) and school environment (r = 0.626, p<0.05) were significantly related to students’ academic performance in Integrated Science. The study concludes that parental influence, home environment and school environment influenced students’ academic performance in Integrated Science in Ekiti State Tertiary Institutions. It was recommended among others that parents should give moral and financial support to students, while tertiary institutions should be supported and well-funded by the government at all level to create conducive environment for teaching-learning process.
