The study investigated electronics works competencies required by electronics teachers for effective teaching in technical colleges in Osun and Oyo states. A survey research design was used for the study. A 48-item questionnaire was used as instrument for data collection and three experts validated the instruments. A reliability coefficient of 0.879 was obtained and 49 electronics teachers were used. Three objectives were stated, research questions asked, and hypotheses formulated and tested at a 0.05 level of significance. Mean and standard deviation were used to answer research questions and the t-test statistic was used to test the hypothesis. The findings revealed that electronics teachers in technical colleges required competencies for effective teaching in the soldering and de-soldering techniques, troubleshooting electronic circuits, testing devices and cards with measuring instruments among others and the result of the null hypothesis shows that there is no significant difference between the mean responses of experienced and less experienced electronic teachers in technical colleges on competencies required to teach electronic devices, electronic circuits and radio communication. This study implies that demonstration method is appropriate method of teaching competencies in electronics works in technical colleges and if competencies identified in this study are used by the teachers, it will help the students to be self reliant when they graduate. The researcher offers recommendations that the government should provide in-service training programmes for electronic teachers, adequate materials and tools for electronic teachers and that competencies should not be used for evaluating electronic teacher for layoffs.
