Depends on the school. Overall, though, it seems like very few schools actually do grade placement based on MAP scores. If you are lucky they use them as a screening tool and will then to other achievement testing.
This is a really polite version of what I was going to relate about our experience (middle school). To use MAP scores for placement, someone in the school would have to actually *look* at them. When I did some stealth agitating last year, I received a call from the school learning coordinator (also the in-building TAG contact), and when she called, she said in an awed/stunned tone "I knew [name of DD} is bright, but I just looked at her MAP score, and I don't think I've ever seen one that high." This wouldn't be so irritating if they didn't make such a big deal about how they are totally on top of TAG identification and services (and MAP is an advertised element of this, albeit only in its 2nd year) so that parent requests are unnecessary/unwelcome.
Know your school.
