PSAT Score Calculator: Selection Index and National Merit Cutoffs (Class of 2027)

National Merit doesn’t use your PSAT total. It uses the Selection Index, and each state sets its own Semifinalist cutoff every year. This calculator computes your index and compares it with the cutoff for your state.

How the PSAT/NMSQT is scored

The PSAT/NMSQT uses the same design as the digital SAT: 98 questions in 134 minutes. Reading and Writing has 54 questions in 64 minutes, and Math has 44 in 70. The test is adaptive, with two modules per section. Only the scale is different:

Selection Index = (2 × RW + Math) ÷ 10

Section scores move in steps of 10, so the index is always a whole number. Reading and Writing counts double: +10 RW adds 2 index points, while +10 Math adds 1.

Worked example

A student in California scores 690 in Reading and Writing and 700 in Math.

• Total: 690 + 700 = 1390
• Selection Index: (2 × 690 + 700) ÷ 10 = 2080 ÷ 10 = 208
• California, Class of 2027: cutoff 220, so the student is 12 below
• Commended (national): 208, so the student meets it exactly

Closing a 12-point gap takes about +60 RW (6 steps × 2 points) or +120 Math. Over two classes, California’s cutoff moved from 224 to 220. The table under the calculator shows four classes for the state you pick.

If you only have practice-test counts, switch to “Correct answers.” For example, 46 of 54 RW and 38 of 44 Math scale to about 650 and 640 on Practice Test #3, with ranges of 620–680 and 610–670. That’s an index of about 194, somewhere between 185 and 203.

Class of 2027 Semifinalist cutoffs by state

These cutoffs apply to the October 2025 PSAT/NMSQT. Official cutoffs went to schools on September 9, 2026. The figures below are compiled by Compass Education Group, because NMSC does not publish a public state-by-state table. Commended was 208 nationally (210 for the Class of 2026). Studying Abroad was 223 and U.S. Territories 208. For longer trends and how the cutoffs are set, see the National Merit semifinalist cutoffs by state research page.

How many questions can you miss for National Merit?

Cutoffs are set in Selection Index points, but on test day you count questions. The table turns the gap into correct answers. It uses the calculator’s “Correct answers” mode: digital counts scaled onto College Board’s Practice Test #3 table, with the midpoint of each range as the estimate.

Estimated Selection Index for sample PSAT/NMSQT results (Practice Test #3 table, all 98 questions counted)

Worked example. Compare rows two and three. A perfect Math section with 7 Reading and Writing misses gives 207, one point short of the Class of 2027 Commended cutoff of 208. Spreading 8 misses as 5 in Reading and Writing and 3 in Math gives 208 and meets it. Reading and Writing counts double, so near the top each RW question is worth about two index points.

The ranges are wide. A 216 estimate could be anything from 209 to 225, which spans most of the state cutoffs in the table above. Use the counts to set a practice goal, not to predict your official result. To plan the SAT that follows, the SAT score calculator uses the same method, and the ACT calculator’s SAT to ACT conversion shows how the two tests line up.

What the cutoff numbers mean

Your state’s cutoff is the lowest Selection Index that qualified a student as a Semifinalist in that state for that class. Meeting it is enough. States with more high scorers relative to their allocation have higher cutoffs. That’s why New Jersey and the District of Columbia sit at 223 while Wyoming sits at 208.

Compass reports that NMSC recognizes about 55,000 high scorers each year: roughly 16,500 Semifinalists and 39,000 Commended Students. Commended uses a single national cutoff, so a 210 is Commended in every state but makes Semifinalist only in states with a cutoff of 210 or lower.

How much cutoffs move from year to year

From the Class of 2026 to the Class of 2027, every state’s cutoff fell. The average drop was 3.2 points. The largest was Alaska (215 to 208), and Delaware, Hawaii, New Mexico and South Dakota fell by just 1. Over the four classes in the tool, 43 of 51 states had a spread of 3 to 5 points between their highest and lowest cutoff. That’s the honest margin when you guess at a future year:

• Above your state’s highest recent cutoff: you’re in a strong position.
• Within 2–3 points of it: it could go either way. Keep preparing for the SAT regardless.
• Below its lowest recent cutoff: aim for Commended (207–210 over these four classes) and use the PSAT as SAT practice.

Next steps

• The PSAT is practice for the SAT. Estimate that score with the SAT score calculator.
• Considering the ACT instead? Compare with the ACT score calculator.
• Track AP exams with the AP score calculator and your GPA alongside test scores.
