The Class of 2003 presents new research on barriers to post-secondary education (PSE)1 in Canada. Building on the barriers identified in the Canada Millennium Scholarship Foundation’s 2002 and 2004 editions of The Price of Knowledge, this survey presents new data on barriers relating to interest and motivation, finances, and academic requirements. The box below lists types of barriers to PSE which have been defined previously. This report examines the extent to which various factors limit access to PSE and how these barriers interact. More specifically, the study presents the impact of multiple barriers on œfirst-generation students (i.e., the first generation in a family to pursue PSE), and explores the PSE aspirations, attainment and barriers of Aboriginal students.
