I would complement that with the importance of providing good information about post-secondary education options to students early, early on in high school, and even in elementary school.
Also, from the college sector, I think there's still some awareness building to provide. Colleges have changed dramatically in the last 50 years. What they are offering and the career options that they support are really quite impressive.
Last week, I was at Algonquin College in Nepean. The school year has ended, so the campus is not full of the regular students, but there were busloads and busloads of grade 8 students visiting the campus for the day, having a look around, looking at the labs, looking at the classrooms, and interacting with the faculty. They were wide-eyed at what was on offer there. Things like that are also supported by a lot of the dual credit programs that are being offered. Students can get a credit in high school that is also a credit towards a program at a college or an institute.
As I say, this demystifies, this opens the door, and it gives them some ideas. I think that most kids coming out high school just need that spark of “what is it that I'm going to do?”
