Revisiting the topic of above-level assessment with update and additional questions. :-)

A gifted-experienced psychologist suggested to me last spring that DD might take the state assessments for 3rd grade in 2nd to look into proper instruction level.

I'm thinking ahead to her fall needs, if not earlier. DD's getting some above-grade math extension this year and it's going decently (her teacher is pretty creative with math), but DD's not really getting deep ELA extension (they offer some differentiation at below-meeting-above levels), despite reading 2-3 years above grade-level, and that's now sent literacy to the bottom of her list at school (math is now favorite, a huge positive swing, but reading is below all other subjects, because she's tired of reading pages that have a few two sentence paragraphs that have no detail to find things she already knows, like the main idea). I'm assuming we'll need some scores or another to see where she needs different instruction.

So now, the regular state timed testing is coming up, but it is not done at her grade level. I still don't know, should I ask about her joining the 3rd graders for that?

Or might it be better to ask for the MAP 2-5 test? They offer that in fall and spring to grades 4-5. Is that a test you can take any time -- so she could just take it this winter to see how she compares to above-grade level?

Is there something better we might request? Either way, I feel like 'that parent' when I ask for this stuff, so I want to go in with solid info to support her needs (needing challenge), as the school will just continue to use classroom cluster differentiation.
