As you probably know, NWEA MAP is an adaptive achievement test. Typically, we don't prepare for it (I have 2 children who take it 3 times a year), but try to focus on always learning something new...which seems to work for them.

Is your DC taking K-1/2 or 2-5, because they are different tests? Our schools give all of the second graders the 2-5, but some schools give their second graders the K-1/2.
