I would proceed with caution. P-MAP is not MAP 2-5. It does not have as many tough questions available. DYS DS7 also scored high on P-MAP last year (higher than the average 8th grader!), but his score did dip when he took the 2-5. DS said it was harder than the test he took in 1st grade. His score is still quite high, but just be aware that the 2-5 test has a different question bank and although the RIT scores are supposed to be continuous, I would want him measured on the higher level test (which is probably what the students in the older grades take).
Still, your DS is likely advanced. Can the school give him the grade 2-5 exam to better assess where he is at in math?
Can he keep up with the amount of writing required of a 4th grader? DD's 4th grade math required a great deal of written explanation (sometimes, it looked more like a writing class).
It is GREAT that your school is so open minded about acceleration, though! DS's school was not.
