The only difference in PMAP and MAP is the headphones. There is no ceiling.
Just wanted to clarify for the OP- there is a ceiling on PMAP/MAP testing :-) It is just way out there so you don't really need to worry about your K student hitting it just yet. The reading ceiling is somewhere near 260 I've been told by our school and this makes sense because 99th percentile for 11th grade is 252 in the national norms. Math supposedly stops at 280 according to our school.
I've been told by others outside our school that all the tests go to 300 but it seems like the ceiling is 11th grade either way. Growth goals get smaller as the scores get higher. You would expect a 1st grader to make larger gains in a year, score wise, than an 8th grader.
Welcome! You've gotten some really great advice about achievement testing and getting a copy of the IAS. We were able to use our son's MAP scores to get a full skip last year and it was by far the best thing we could have done for him. His MAP scores were in the 96-99th percentile for the next grade up so it was an easy discussion to have.
