The study investigated teachers' perceived problems of curriculum implementation in tertiary institutions. The need for this study was borne out of the concern over prevalent questions raised against the standard of the education system. Three objectives were pursued; to identify perceived problems, causes, and possible solutions to curriculum implementation. 480 purposively selected teachers of tertiary institutions constituted sample for the study. A validated questionnaire with 3 sections constructed by the researchers formed the main instrument of the study. Data generated were subjected to statistical analysis using frequencies, means and ranking. The findings revealed the most frequently occurring problems, causes and possible solutions of the curriculum implementation. Based on the results obtained from the study, it was recommended that heads of departments and deans of faculties should be made to incorporate the task of monitoring their colleagues to the administrative task, a review of the curriculum to meet contemporary need of the society and the need for a paradigm shift of some educational policies to result oriented policies so as to enhance proper curriculum implementation.
