The study takes an in-depth examination of the extent to which the availability of resources relates to the efficiency of the school system within the framework of the implementation of competency-based teaching approaches in Cameroon. The study employed a mix of probability sampling approaches, namely simple, cluster and stratified random sampling techniques to select the 375 teacher-respondents and purposive sampling technique to select the 26 principals for the study. Data collected through questionnaire and interview schedules were subjected to descriptive and inferential statistical analysis using the Statistical Package for the Social Sciences (SPSS) Version 20.0. The findings indicated that there is a significant relationship between the availability of resources and the efficiency of the school system. The magnitude of the relationship that exists was rated low. It is thus recommended that a legislation that institutes an education tax on all workers of the formal sector in Cameroon be enacted to take care of the inadequate resources.
