Most 13-14 year olds would still be in school if we made the requirement to end compulsory education after passing a qualifying test.
However, compulsory education should end at age 16 whether or not one has passed a basic test for competency in reading, writing and math. At age 16 kids should either be headed to college or to a trade school. This is the standard expectation in most other Western countries.
I agree. I'd also lower the child labor age limit to 16.
