The six hypotheses were tested at 0.05 significance level.The population of the study was 1,157 private schools and 3,563 public schools, 647,952 male students and 309,799 female students. A sample size of 10,487 students comprising 6,267 males and 4,220 females SSCE results from seven private and seven public schoolspurposively selected was used for analysis.The study adopted Ex-post facto research design.A proformatitled: Senior Secondary Students Academic Performances (SSSAP) used for the study to collect data.The data collected was analysed using percentages and Chi-square statistics.Two of the hypotheses were retained and four were rejected.Thefindings revealed that there was no significant relationshipin the performances in English Language and Mathematics between male and female students in WASSCE in North-West Zone, Nigeria. However, findings shows significant relationship existed in the performances in English Language and Mathematics between private and public and urban andrural schools in WASSCE in North-West Zone, Nigeria. It wasrecommended among others that officials ofministry of education in the seven states should regularly carry out routine supervision of instructions and monitor performance standards in English Language and Mathematics with a view to improving the quality of delivery.In addition, ministry of education in the seven states should encourage and motivate the teachers from the rural schools by sponsoring them to attend seminars and workshops in English Language and Mathematics in order to broaden their knowledge, reduce the failure rate, bridge the gap with students from urban schools and remove the misconception that these subjects are difficult especially Mathematics.
