Can ninth graders take the PSAT/NMSQT?

Yes, but they won't be eligible to enter the National Merit Scholarship Program. The PSAT/NMSQT is designed for 10th and 11th graders.

Some schools offer the PSAT 8/9, which tests the same skills as the PSAT/NMSQT, but in ways that are appropriate for earlier grade levels. Check with your child's school counselor to see if your school offers the PSAT 8/9.
