I must be really out of the loop ... I had no idea about these K12 assessments. LOL I have always just looked at the requirements for Kindergarten and 1st or 2nd grade; judging DD's abilities against these guidelines to know where she aligns but having the assessments has been interesting. DD (3 yr 5 mths) is clearly aligned with 1st grade for language arts and 2nd grade for Math. I don't know if I would call it eye opening for me since I already estimated her at that level, but it is definitely nice to concrete her advancement via the assessments which then helps me see where to go from there.
