It is generally accepted that Canadian postsecondary education enjoys an international reputation for quality. However, Canada does not have an accepted, national framework to understand, measure, or clearly define the actual quality of the postsecondary education sector. In this, Canada is seen as unique when compared with other developed countries. Canada has 13 educational jurisdictions (provinces and territories), each with different institutions, and institutional mandates and missions. One of the results of this structure is that agreement on how to conceptualize and assess quality across the Canadian postsecondary education sector becomes a complex challenge. A single approach may not be acceptable, or appropriate, if applied on a national level. As education is a provincial responsibility with federal "transfer funding", consideration in this article will be mainly on the Ontario situation. The system for post-secondary education in Ontario consists of three main types of institutions: universities, publicly assisted colleges, and private career colleges. In Ontario, the provincial government has articulated its priorities for postsecondary education as being: Accountability, Accessibility and Quality. In terms of quality the challenges and issues are complex. The fact that the concept of quality is hard to define, and therefore hard to measure, simply adds to the complexity of the challenges. The purpose of this article is to describe how the public college sector is moving forward to address the quality assurance issue within its institutions. (Contains 4 tables.)
