The accreditation of diploma engineering programmes is almost negligible in the country. It is a matter of great concern. The researchers conducted a descriptive cross-sectional study to design strategies to encourage polytechnic colleges to improve the quality of diploma engineering programmes and apply for obtaining accreditation in the next two years. A brief review of the literature revealed that studies are not available on polytechnic education and whatever is available can not be replicated in changing scenarios of polytechnic in the context of the national education policy 2020. Researchers designed instrument used to know the views of officials and faculty members on strategies at the state, polytechnic, and faculty members levels. The researchers received 525 responses to the research questions that were classified, analyzed, and interpreted to articulate the strategies at three levels. The responses indicate that there is a need to assuring the quality of education at the state, polytechnic, and faculty members levels, innovate it and sustain it in the context of developments taking place in the industry and technical education. Limitations of the study and areas for study are suggested.
