The study focused on achieving sustainable development through Technical and Vocational Education and Training in a developing economy of Imo State, Nigeria. Two research questions and two hypotheses guided the study. The descriptive survey design was employed for the study. The population comprised 2846 Academic Staff in the two Polytechnic’ Institutions in Imo State, Nigeria. The sample size was 351 Academic Staff (Federal Polytechnic = 216; Imo Polytechnic = 135) representing 12.3% of the population. The proportionate stratified random sampling technique was used to draw the sample. An instrument titled “Achieving Sustainable Development through Technical and Vocational Education and Training Questionnaire (ASDTVETQ)” which was validated by experts and with reliability coefficient of 0.78 was used for data collection. The descriptive statistics of mean and standard deviation were used to answer the research questions and z-test was used to test the hypotheses at 0.05 alpha level. The study revealed among others that numerous constraints militate against effective technical and vocational education and training for sustainable development in Imo State, Nigeria. It was recommended among others that the Government should as a matter of policy give priority to TVET in the nation’s educational programmes to ensure sustainable development.
