Assuming they graduate, they ae going to be 'tested' in life.  

ACT, SAT, just to get accepted at a college.  College Placement tests to see if Oregon K-12 actually  taught you either English or Math.

Tests to see if you can be accepted in an electrician apprentice or other specialized training course.

The Military aptitude tests to see what you can be trained to do in the military, if anything.  Or whether you can even become an officer.

Private employers are actually doing some testing as well.  They don't want to waste a lot of corporate money training someone specific to their industry if the prospect isn't going to measure up.

A parent who refuses to let their chicks take a test is going to wind up with a full nest.
