The study assessed the adequacy of instructional resources available for business education programmes at the colleges of education in Edo and Delta states of Nigeria in relation to the standards stipulated by the National Commission for Colleges of Education (NCCE). The study adopted the ex-post facto research design and was guided by five research questions. The population of the study comprised all the six business education departments of the colleges of education in Edo and Delta states of Nigeria. The entire population was studied in terms of adequacy of instructional resources. The data for the study was collected through direct observation using the NCCE benchmarks as inventory and analyzed using ratio and percentage scores. The study found that lecturers and physical facilities available for business education programmes are adequate in some of the colleges and not adequate in others. Equipment and supplies in the typing laboratories, shorthand studios and model offices were found to be grossly inadequate in all the colleges studied. Based on these findings therefore, it was concluded that students of business education in these colleges of education are learning without the necessary and required instructional resources for effective development. To this end, it was recommended among others that the National Commission for Colleges of Education should regularly supervise the programmes of business education and ensure that their stipulated standards are maintained.
