To go even slower:  256 appealed, the report shows that 60% or about 140, submitted additional testing.
We do not know how many kids took the WISC and did not apply when there parents saw the results.  You do not appeal with scores of 115....

However, I will suspect that the GT process results in about 1000 kids taking the WISC....

That is a self selecting group, not random.  Factors leading to taking the WISC are upper 75% on the tests AND low GBRS.

so of the 1000, 80% probably scored below 125 (based on distributions).  Those will not appeal.  of the remaining children will be 125 and above, with 1/2 being between 125 and 132 (based on distributions).

As it turns out, 128 seemed to be the magic number on WISC.  So of the 1000 kids that took the wisc, presumably 200 submitted the scores through appeal, 150 had scores that were acceptable.

Without WISC scores, the committee tries to identify the smart kids using criteria with know / documented issues.  If the CogAT or NNAT were sufficient, there would be no GBRS.  If the county could afford to give every child a WISC, there would be no GBRS. CogAT+NNAT+GBRS give about a 90% probability of identifying smart kids.  However, it probably misidentifies about 20-30% of the kids as smart when they are not.  That is the regular process.

With WISC, the probability of detection is higher, probably 95%.  The false alarm rate drops to about 10%.  So, if anything the appeals kids, on average, are smarter.[/quote]

Actually the report  shows that  out of 256 total appeals, 100 appealed with WISC, 156 appealed without WISC. 
Quiet number of people appealed without WISC.

My guess is that many of the scores like 115, appealed anyways without including WISC instead of just giving up.  
They went that far so at that point, you don't lose anything by appealing.  However they don't include the low WISC.

Some appealed without taking WISC in the first place due to $ constraint.
Also, most of these kids who are taking WISC were already in the pool - Already above average kids. 
So I think 1000 maybe too high.  Somewhere around 500?
