To convert a PSAT score into an NMSQT score (which is used to rank students for the National Merit Scholarship program), you take the three subsection scores of the PSAT (Reading, Writing/Language, and Math), double them, and add those together.
For instance, a student with a near perfect score on the PSAT of 36 on the Reading (out of 38), 36 on Writing/Language (out of 38), and 35.5 on the Math (out of 38) would have a 215 as their NMSQT score. Thus, in NJ, students can miss a combined 3 subsection points on the PSAT (so they could get a 37 in all three sections — out of 38 in each section — and just hit the Semifinalist cutoff of 222 on NMSQT selection index).
Thus, it’s important to note that, while Math scores are 1/2 of a student’s PSAT score (Verbal out of 760 + Math out of 760 = 1520 possible points on the PSAT) and also 1/2 of a student’s SAT score (Verbal out of 800 + Math out of 800 = 1600 possible points on the regular SAT), Math scores are only 1/3 of the total NMSQT score used for the National Merit Scholarship Program. Thus, on the PSAT, the Verbal section (comprised of the Reading section and the Writing/Language section) is twice as important as the Math section for the final NMSQT score.
