"doing well in school is consistently the strongest predictor of doing well in school"
And if they aren't going to perform well in school maybe they shouldn't be going to school?
The US has a huge shortage in the trades because we stopped telling high school students to go into plumbing, welding, electrical, etc. Suddenly the 'poor' student that would have excelled in something hands on like a trade were told "Go to college! You'll make more. Just pick something you like."
It's why we have a ton of "college graduates" that can't find a job because we don't need more Psychology majors with only a BS.
