Re: Converting scores to national percentiles

["ElsaHaas" <ElsaHaas@si.rr.com>]

I think I'm going to give up on this for now, and continue to tell parents
that I don't know. 

Most of the information I've been turning up about the state tests tells
what percentage of kids (in NYC vs. statewide) has "passed" for a particular
year, which doesn't tell me anything about what percentage scored a 4 (the
top score). And then even if I knew that percentage, I don't know how I
would figure out what percentage of kids nationwide would have scored a 4,
which is what I would have to know to say what a 4 is equivalent to as a
national percentile. 

I suppose you could use the NAEP somehow in this conversion, by knowing that
a certain percentage of kids in NYC tends to "pass" (score at a "proficient"
level), as opposed to a lower percentage of NYC kids on the NAEP (if the
NAEP results are even broken down to the level of cities). But so far it's
too complex for me, and I don't have enough information. 

In any case, parents can't trust that just because a kid scored at a certain
percentile on one test, s/he will do as well on another test. 

Thanks, 
Elsa
