Wow. We recently moved from a very "smart" district. The high school is regularly either first or second in the country. It used to be that about 15% of the second graders in the district would score 99% on the nationally normed CogAT. They also use a nonverbal test. I think it is called the NNAT. In the end something like 30% of the population were eligible for some kind of gifted services. This year I heard they were doing things differently with the CogAT to try to accurately tease the top 5% in the district for the gifted magnet schools. So, I think it is district-normed now. This school district is also having a hard time with prepping.
The stories I hear are crazy, and I am so glad we do not have to deal with that.
