Despite physics' significance to society, there are many flaws and variations in secondary school students' performance in the topic, which is why this study focused on teachers? quality as predictor of secondary school students? academic achievement in physics. The study was led by two objectives, two research questions, and two hypotheses that were examined at the 0.05 alpha level. The design of the correlation survey was chosen. 2720 senior secondary two (SS 2) physics students from all public secondary schools in the Onitsha Education Zone made up the study's population. A Sample size of 408 SS 2 students offering physics in the Education Zone was drawn using two stage sampling procedure. Students Rating of Teachers? Quality (SRTQ) and the achievement scores which was obtained from physics teachers? grade book for 2023/2024 academic session from the sampled schools were used as instruments for data collection. Three specialists verified the instruments. To determine the instrument SRTQ's dependability, the Cronbach alpha method was used. A reliability coefficient of 0.71 was determined for SRTQ. Data collection was done using the two equipment. In order to answer the study questions, the coefficient of R and R2 were employed, and the hypotheses were tested using regression ANOVA (both linear and multiple). The findings from the results revealed no discernible effect on either male or female students. The study also discovered a minimal positive predictive value between the academic achievement of secondary school students in physics and the quality of their teachers. Regardless of gender, it advises educators and the government to find more variables affecting student accomplishment besides teacher quality
