The idea that you can guarantee the integrity of a test by making it so super-secret that no one can know what's on it was IMO a silly one to begin with. A good test is one where you know exactly what's going to be on it, but it's still challenging enough that you're not going to do well on it unless you genuinely know what you're doing.
Do you think kids should prep for CoGAT or WISC?
DP. I think admissions should use tests like PSAT, where prep materials are readily available, and prep is assumed, but where it has a somewhat limited effect. Even aside from the Curie controversy, it's absurd to imagine that kids wouldn't tell younger relatives or friends about the types of questions on the Quant Q. Other than the first year Quant Q was given, it was always going to be the case that some kids would have unfair knowledge of the types of problems on the test.
The question was for CoGAT or WISC.
Why are you so concerned with what people "should" do? The reality is that people will prep for CogAT and WISC. If it's important to a school or program to get un-prepped scores or to level the playing field, then they shouldn't use tests that people "shouldn't" prep for but will anyway. Honestly, in FCPS, they probably should provide prep materials for CogAT to everyone.
The scores wouldn't be valid in an absolute sense, but they'd be better for gauging relative ability among all students.
