YEs, I read at the NWEA site that the RIT score is INSTRUCTIONAL level rather than mastery level. But what level do I use? He score >99th% of 1st graders, 95th% for 2nd graders and at 74th% for 3rd graders and at 47th% for 4th graders. WE're HSing so it really doesn't matter, we'll keep doing what we're doing but just curious how a school would look at this score. Would they say he's perfectly placed for going into 2nd grade?
