Thanks, Lauren, I appreciate your info. I recently signed ds up for EPGY, to supplement what's going on at his montessori school - mainly to fill in any holes and then keep him moving forward. In order to make sure holes are filled in, I started him in his actual grade level (2) in EPGY. Unfortunately he doesn't have time to do it every day (or at least he isn't interested in doing it during the times when the computer is available!). So, we haven't gotten to a point where he's learning significant new material, though he can always use the practice on the lower grade material. My guess is that he's probably operating around a beginning of fourth grade level, though the Star test said something in the middle of fifth, which is why I don't think the Star result is accurate.
So, it sounds like Star may be less than accurate in both directions, if it's giving you a grade level that is less than where your ds is at in EPGY. hmmm.... Well, at least the Star test result seems to be motivating my ds's teacher, which makes it very useful to me
