In the end, it actually doesn't matter what the SAT and PSAT measure. In the real world most people realize it's a game to some extent, a game that's worth mastering. There is a TON of money riding on those tests. It's a bit nuts for your school to say the tests don't matter when they CLEARLY matter for scholarships and admittance.
I understand a school not wanting to be in the "business" of teaching to any standardized test, but to tell you the test doesn't matter is ludicrous.
I think most of the prep type schools around here offer SAT prep classes before or after school.
btw: I disagree about the small class size argument. Once you get to the "pricey college prep" schools, self-selection is already well underway. Those kids are typically ready and able (with varying amounts of prepping) to do well on the test. Around here typically 5-15% of the students at the priciest prep schools are NMSF.
