<p style="text-align:justify">Compliance with any policies, laws and regulations, including university compliance with quality assurance mechanisms globally, depends on the practicability of those mechanisms. Like other countries, Tanzania has quality assurance mechanisms that require universities to comply. However, the existing audit reports have shown non-compliance cases to such mechanisms. This study sought to explore the practicability of the existing quality assurance mechanisms in promoting universities’ compliance in Tanzania. The documentary reviews, interviews, and focus group discussions were used to collect data from the 4 universities and 46 students, academics, and quality assurance directors and officers as a sample size selected purposively. The data were analysed through content analysis. The findings revealed that the existing quality assurance mechanisms are generally practicable; however, there are quality assurance requirements with practicability challenges due to contextual factors. Such requirements include senior academics in administrative duties, academics’ promotion, academics’ recruitment, inclusive and participatory teaching approaches, requirements with extra financial costs, examination scripts’ marking, and invigilation restrictions. This study concludes that the practicability challenges of some quality assurance mechanisms are one reason for non-compliance cases at some Tanzanian universities. It recommends that key stakeholders be involved in establishing mechanisms, and all contextual factors must be addressed to enhance practicability.</p>
