The study appraised the predictors of product quality in colleges of education in Nigeria and quality of NCE graduates in Secondary school level. Three research hypotheses were formulated to carry out the study. Six colleges of education drawn from both public and private colleges of education were used. Thirty-six Principal Officers were used as respondents to the 15-item questionnaire that was used. Simple percentages and means were used to analyze the data. The result shows that there was no significant difference in the position of physical facilities in the sampled Colleges of Education. It also Showed that all the four available educational resources when combined, have no correlation with quality of NCE graduates (r= .066, N= 161, P>.05). Therefore, availability of educational resources had not influenced quality of colleges’ graduates. The result further showed that there is a positive significant relationship between Availability of teaching staff and rank compositions with the quality of university graduates in selected institutions (r = .475**, N= 161, P < .05). This finding was not surprising because the situation in all the sampled Colleges of Education appears to be the same.
