Skills gap for high-school to university transitions I can find a bunch of articles about the skills gap between university graduates and job requirements, but it seems that there are limited resources on the skills gaps that high school students have coming into university.  Does anyone have any good references that might illuminate any skills gaps?  I'd prefer a world-wide perspective, but that might be asking for the moon.  I'm in Canada, and specifically Ontario, working in STEM.

To be fair, I can definitely pin-point some things I've personally observed, but I'm looking more for data and studies that are more in-depth than my personal anecdotes will allow.
In the US, the ACT College Readiness Benchmarks reflect academic skills that students should have before entering college.  Sadly many high school graduates don't meet these standards and end up in remedial classes to make up for their lack of preparation.
