The interface for the MAP P is very different from that of the MAP 2-5. The MAP P reads the child the question and has a lot of graphics. The higher versions require the child to read the questions him or herself and there are fewer problems that are "game-like" and require things like dragging and dropping.
From what we've been told many schools are don't like to move children who are very young up to a higher MAP test because they are concerned the child's reading skills may influence their performance and give them a lower result than their actual knowledge.
