This study assessed the influence of teachers' variable on academic achievement in biology among secondary school girls in Ibadan North Local Government Area, Oyo State, Nigeria. Methodology: A descriptive survey research design was used and multi-stage sampling procedure was employed to select the 20 teachers who participated in the study. Ten public secondary schools in Ibadan North Local Government Area of Oyo State, Nigeria were randomly selected. A self-designed instrument titled: Teachers' Variable on Academic Achievement in Biology Questionnaire was analyzed. Two research questions were answered; percentage, Pearson moment correlation analysis and multiple regression analysis were used to test the two hypotheses at 0.05 level of significance. Results: There was no significant relationship between teachers' academic qualification and academic achievement among secondary school girls offering biology in public secondary schools in Ibadan North Local Government Area of Oyo State (r = 0.412; df=18; p>0.05). Furthermore, with respect to teachers’ teaching experience and the academic achievement, there was no significant relationship (r=0.324; df=18; p>0.05). Consequently, the connection between teachers’ academic qualifications did not correlate with academic achievement among secondary school girls offering biology. Recommendations: The study recommended that the state government should prioritize teachers’ educational qualification in biology in public secondary schools in Ibadan North Local Government Area of Oyo State, Nigeria.
