California instituted a standardized test that high school students had to pass in order to graduate quite a few years ago (I think I took it as a sophomore, in 2003 or 2004). Any 8th grade student in my district should have been able to pass it easily, but apparently there were students throughout the state that were repeatedly failing it (and, even worse, in my high school).
Also... it only tested math and English.
Standardized tests are lame.
