This study adopted ex-post-facto research design to investigate teachers’ bias in assessment process in selected secondary schools’ subjects. Cluster sampling technique was adopted to select ten schools from the three senatorial districts and simple random technique to select 500 students per subject making a total of 50 students per school. The research questions raised were analyzed using regression model of statistical moderation coefficient of skewness, Pearson-product-moment correlation statistical technique and analysis of variance (ANOVA). The result confirmed the existence of teachers’ bias in the assessment process in mathematics, English language and biology with prevalent errors of leniency and severity. Based on this, the study recommended the need for standard statistical moderation of school based assessment scores that would minimize the errors of leniency and severity in the assessment process which will ascertain quality control of teacher assessment scores in Nigeria secondary schools.
