So how do you go about getting a accurate score if they hit a ceiling? A different test?
In general testing one approach is to give a test with lots of 'headroom' - that's the idea behind the 'talent searches' that encourage parents of 7th and 8th graders to sign their kids up to take a SAT/ACT test that only counts for qualifying for the Search's educational programs.
But with IQ tests, there is no different test - (except in the case of 5 and 6 year olds taking WPPSI vs WISC) one generally just has to accept that the IQ tests aren't built to detail out the differences of kids in the top 2% of the population.
Hope that helps,
