I just wanted to say that last year my DD took the STAR test twice in one day (there was somehow some confusion about whether she had taken it the first time)- I think literally 15 minutes apart- and she managed to score *2 years* different from one test to the next. Both were quite a bit above grade level, but it's such a short test that apparently it can be a bit volatile. Over the course of the year, taking it basically every month, you could see an upward trend, but you couldn't get a truly accurate picture looking at each score in isolation.
