Teaching practice is a mandatory requirement for graduation from colleges of education in Nigeria. Hence, this study sought to find out the variance components for persons, occasions and person crossed with raters and residual, generalizability coefficient and the dependability index (indices) in the teaching practice assessment. Scores of 1, 393 students who participated in the 2016/2017 teaching practice course were obtained and analyzed using variance components (VARCOMP), relative error variance, absolute error variance, and indices statistics. The findings of the study revealed that: variance accounted for in the 2016/2017 students’ teaching practice assessment were; persons (o2p) = 0.02, occasions (020) = 0.03, interaction of persons with occasions (02p0) = 0.05 and residual (02prqe) = 0.15. In addition, generalizability coefficient of 0.84 and dependability index of 0.74 were obtained. The study thus concluded that the indices of students’ scores in 2016/2017 teaching practice were high or acceptable. This implied that the quality of students’ scores in teaching practice course was standard. The study recommended that the sixteen weeks slated for teaching practice should be maintained.
