Educational measurement is quite different from psychological measurement (in
a strict sense) both in theory and in pratice. The state testing program that
I've worked on has a routine sample size of 30,000 for each form of the test
in each administration. And think about the SAT or tests made at ETS, while a
typical social psychological experiment in JPSP has a sample size that's
roughly 1% of a typical state testing program.
