What is the NWEA MAP Test? The NWEA MAP Test is an adaptive achievement test that allows educators and parents to measure student performance and growth. The test creates a personalized assessment experience by adapting to student responses. The NWEA MAP test is offered in more than 7,400 schools nationwide. Unlike many tests, the NWEA MAP test provides each student with a unique set of questions based on their responses to previous questions. If a student answers a question correctly, the questions become more challenging.
