Outsider,  The Nation's Report Card, known as the NAEP test, was highest when there were only 3 or 4 short standardized tests in a student's entire k-12 career.  But now kids take 120 standardized tests, some over 11 hours long.

It's simple math that increased testing reduces learning time and costs more.  We now spend 35x more on standardized testing than just 7 years ago.  

The result?  There isn't enough money for science labs, civics, health, PE, music, art, shop, nurses or the counselors needed to advise students on college and career choices.  Further, outside measures like the NAEP haven't budged.  

We only need a few, high quality standardized tests to compare students, classes and schools.  Meanwhile, multiple studies show unit tests are far more relevant to learning, and grades are the ultimate predictor of college or career success.

Overtesting isn't working and it's not worth it.
