I'm certainly willing to consider the possibility that it's been taken too far and some reasonable balance should be strived for. However, anyone that suggests that a student shouldn't have to demonstrate a minimum level of proficiency in the basics...reading, writing and arithmatic...in order to receive a HS diploma is implicitly suggesting that a HS diploma shouldn't be worth shit.
Who is saying that they should not be tested at all?
I think this is why Texas is shifting to End-of-course exams.
