The Association of Canadian Community Colleges (ACCC) is the national and international voice through which Canada's colleges and institutes inform and advise various levels of government, business, industry and labour. ACCC's Strategic Focus priorities for 2005-2006 include Aboriginal peoples' access to post-secondary education, and enhancing student success support mechanisms in colleges and institutes which are grounded in Aboriginal values, culture and tradition. In April and May 2005 ACCC initiated a study on Aboriginal programs and services at colleges and institutes. The study included a literature review, an on-line survey for mainstream ACCC member colleges and institutes, and interviews with representatives from Aboriginal and northern ACCC member colleges and institutes, and the Aboriginal Institutes Consortium, an Associate Member of ACCC. Of the 140 ACCC member colleges and institutes, 61 participated in the study, 59 mainstream institutions, including the colleges in the three territories, and 2 Aboriginal institutions, for an overall response rate of over 44 percent. This report begins with an overview of Aboriginal post-secondary education trends in Canada drawn from 2001 Census data. The report also provides an overview of the barriers to Aboriginal learners' participation in post-secondary education. Appended are: (1) list of participating colleges; and (2) list of Aboriginal Institutes' Consortium Programs, 2004-2005. (Contains 13 footnotes.)
