Thus the study investigated the influence of age and gender on academic achievement scores of students: A case study analysis of Utagba-Ogbe technical college, Kwale, Delta State. Three research questions was formulated and one research hypothesis tested at 0.05 level of significance guided the study. The survey research design was adopted and the study was conducted in Delta state, Nigeria.

Based on the empirical outcomes of the study, the researcher concluded that age and gender have positive influence on the academic achievement scores of technical college students. The researcher recommended that teachers, teaching in technical college should adopt practical oriented teaching methods that would be of great benefit to the students not minding their gender or age differences. Also, the stakeholders of education should make available necessary instructional devices needed to ensure efficiency in teaching and permanency in learning technical subjects among students of different age and gender.
