Thanks for your response, its been insightful going through your other posts as well.

I have noticed in googling that the SAGES-3 offers the test as 'K-3' and then a version for older children. Does that mean kindergarten students answer the same NVR questions as the third graders? My understanding is the test was 20 minutes for my son, which I interpret as meaning it couldn't have had very many questions to provide differentiation across such a wide age range. The older grades seem to have longer testing windows. Does that mean it�s just the same question but more of them?
