I have admired Murray's work in the past but, if you don't mind, I will take my queue from the largely successful strategy that the NRA has used in defending our Second Amendment rights: If I see a hair on the camel's nose brushing the bottom edge of the tent, I will attack it with fire, poison, machete and every other weapon in my arsenal.
I stand for no-bull$hit ~~testing~~ to hold both the educational establishment and students to measurable standards. The SAT may be superfluous, but keep your hands off any aspect of measuring results and upholding standards. In fact, I suggest that we introduce an additional test, of the same general sort, to build a bit more redundancy in the firewall against the complete collapse of standards.
I believe that there is no shortage of wasteful practices that might profitably be cut from the educational process. Why don't we just right now put out-of-bounds the "reform" of testing. Go reform something else.
