PSAT score calculator: Selection Index and total score

How is the PSAT Selection Index calculated?

The PSAT/NMSQT reports two section scores, Reading and Writing and Math, each from 160 to 760. National Merit Scholarship Corporation (NMSC) turns them into one number, the Selection Index. College Board’s guide gives the formula: “double the Reading and Writing section score and add it to the Math section score. The Selection Index score is the sum divided by 10.”

Selection Index = (2 × Reading and Writing + Math) ÷ 10

The lowest possible index is (2 × 160 + 160) ÷ 10 = 48, and the highest is (2 × 760 + 760) ÷ 10 = 228. Because Reading and Writing counts twice, 10 more points there add 2 to your index, while 10 more Math points add 1.

Same total score, different Selection Index

Your total score and your Selection Index can point in different directions. Every row below is a total of 1400, and the index runs from 204 to 216 depending on how the points split.

When do fall 2026 PSAT/NMSQT scores come out?

It depends on when your school sent in the answers. The fall 2026 in-school testing window ran from October 1 to October 30, 2026, and College Board publishes three release dates for it:

College Board says students age 13 and older who gave a mobile number during testing can see their scores in the BigFuture School app and get a text when they are ready. Every test taker also gets an official score report, and your counselor can give you a copy. If your state runs the test as part of its own program, College Board says to check with the state for its dates.

How does National Merit use the Selection Index?

The fall 2026 PSAT/NMSQT is the qualifying test for the 2028 National Merit Scholarship Program. The NMSC section of College Board’s Fall 2026 Student Guide lays out the timeline:

• October 2026: about 1.3 million students who take the test and meet the entry requirements enter the 2028 program. Nearly all are juniors.
• April 2027: NMSC sends high school principals a list of high scorers, about 50,000 students whose Selection Index qualifies them for recognition, to check their eligibility.
• Early September 2027: more than 16,000 of them are named Semifinalists, the highest scorers in each state, and are told through their schools.
• Late September 2027: about 34,000 are named Commended Students, on a “nationally applied Selection Index qualifying score that may vary from year to year.”
• February 2028: Semifinalists who meet the academic and other requirements become Finalists, and Merit Scholarship winners are chosen from them. The guide counts 7,320 scholarships offered in 2028.

Only the PSAT/NMSQT counts. The guide says the PSAT 10 and PSAT 8/9 “will NOT be considered for entry.” Students who spend the usual four years in high school must take it in grade 11. A sophomore who tests in 2026 and plans four years of high school has to test again as a junior in 2027.

How are National Merit state cutoffs set?

Semifinalists are chosen state by state. NMSC gives each state a share of the roughly 16,000 Semifinalist places based on that state’s share of the nation’s graduating seniors. The guide’s example: a state with about 2% of graduating seniors gets about 320 Semifinalists. NMSC then ranks every participant’s Selection Index within the state, and “the score at which a state’s allocation is most closely filled becomes the Semifinalist qualifying score.”

So the cutoff depends on how everyone in your state scored that year. NMSC notes that qualifying scores “vary from state to state and from year to year.” Students at schools in the District of Columbia, U.S. territories, schools abroad and some boarding schools are grouped into separate selection units.

The Student Guide explains this process but does not list any state’s qualifying score, and this page does not estimate one. Schools are told who qualified in September 2027. If your counselor or NMSC gives you a qualifying score, type it into the comparison box above to see how far you are from it.

What is a good PSAT score?

College Board gives two ways to read a score. The first is grade-level benchmarks, set for each section, which show whether a student is on track for college readiness:

The second is percentiles. Your score report shows an All Tester percentile for each score, based on the last three groups of 10th or 11th graders who took the test. A 70th percentile means 70% of that group scored at or below you. For National Merit, the number that matters is your Selection Index against the qualifying score in your state.

Does a PSAT score predict an SAT score?

The two tests share one score scale. College Board says a student with a 500 Math score on the PSAT/NMSQT “would be expected to also get a 500 on the SAT” on the same day. The ranges differ because the tests are written for different grades: the SAT runs from 400 to 1600, the PSAT/NMSQT from 320 to 1520. College Board treats a later, higher score as growth: a 500 Math score on the PSAT/NMSQT followed by a 550 on the SAT a year later is 50 points of growth.
