http://www.edexcellence.net/foundation/publication/publication.cfm?id=376Here is an interesting website regarding standardized achievement testing.
I don't remember the source, but I read somewhere that the norm group for the Stanford-9 was very old and based on a small group of low to average students. The critic asserted that every state yielded above average results.
I read somewhere else that the best way to determine the actual academic standing of a district is to look at the SAT and ACT results because they are normed every year and there is always a 50/50 split on either side of the mean.
