This work is on The influence of school environmental variable on the academic performance of students in Ado-Ekiti metropoly. The research work is designed to assess the relationship between school environmental variables and students’ academic performance using Agricultural Science. The study adopted a correlational survey design. A sample size of 300 students were randomly selected from six different schools and used for the study. To guide the study, two specific objectives and two null hypotheses were formulated and tested at 0.05 level of significance. Agricultural Academic Performance Test (AAPT) and Agricultural practical check-list were developed and used to gather data for the study. The instruments were validated by three research experts and the reliability coefficients of 0.82 and 0.78 were obtained using PPMC. Data were analyzed and null hypotheses tested using PPMC. The findings indicated that there was a significant relationship between the availability of laboratory facilities and students’ performance in Agricultural Science. There was also a significant relationship between the availability of farming facilities and academic performance of students. It was recommended that secondary schools should create more conducive environments that facilitate students’ acquisition and development of cognitive, psychomotor and effective skills in their academic endeavor..
