StudentsNS prioritizes the accessibility of post-secondary education (PSE) as one of its four foundational values because we believe that education is critical to the growth and development of individual Nova Scotians, their families, their communities, and the Province as a whole. This position paper will identify and describe the major barriers that exist in Nova Scotia and attempt to understand their impact on the post-secondary participation of historically marginalized populations. Existing public policy and programs aimed at preparing Nova Scotians for post-secondary education (primarily the K-12 public school system) are critically examined as well as other policies, programs, and community initiatives that make up Nova Scotia’s system of economic and social supports. Unfortunately, many Nova Scotians face significant economic, social, or other personal barriers in the pursuit of PSE and the many benefits that flow from it. Depending on individual circumstances, facing just one of these barriers could be enough to make PSE an unattainable goal. The sad reality is that many Nova Scotians face multiple barriers at the same time, which perpetuates cycles of multi-generational disadvantage. Based on our analysis, we make a total of 17 recommendations that would allow us to better understand the social barriers to post-secondary access, prepare adolescents for success at the post-secondary level, and make post-secondary institutions more welcoming, inclusive environments for students from historically underrepresented communities.
