National Merit Semifinalist Cutoffs Class of 2018

Even in this “up year,” only New Jersey saw a cutoff of 223 (cutoffs for DC and U.S. students studying abroad are based on the highest scoring state). Several more states were bunched up at 222. These results lend credence to the theory that cutoffs on the redesigned PSAT reach a natural limit. A “lopsided” student has a much harder time of reaching a top SI. On the old PSAT, a strong math student might score a 720 CR, 800 M, and 720 W and reach an SI of 224. A top-notch verbal student could have a mediocre Math score and still reach 224 (800 CR, 640 M, 800 M). On the new PSAT, a perfect scoring EBRW student must now pair that performance with an excellent Math score to reach the same level (760 EBRW and 720 M). While it is possible that a state might eventually hit a 224 Semifinalist cutoff, we think it is unlikely. Unless the test undergoes dramatic changes, we believe that it is impossible for a cutoff to ever reach 225.

Cutoffs increased for the class of 2017 and have now increased again. Will they keep going up? In both cases, the College Board played a larger role than did test-takers in overall score changes. There is not yet evidence that scores are on the rise for future years. In fact, we think it is the least likely case – although not by a large margin – when choosing among “no change,” “lower scores,” and “higher scores.”

Nationally, the ability levels of the top 16,200 students among 1.5 million NMSQT participants is relatively static over any mid-term window. The change for the class of 2017 was as expected as it was dramatic. The PSAT underwent a complete overhaul. The elimination of the guessing penalty and the reduction in multiple-choice answers helped “inflate” most scores. The shift from 200-800 scoring per section to 160-760 per section slightly lowered the top end.

There have been a number of theories to explain the increase in PSAT scores for the class of 2018. Test-takers for the 2016 PSAT had the advantage of additional practice materials, improved test preparation, and increased familiarity (many took the redesigned PSAT as sophomores in 2015). While any or all of these factors may have had some impact, Compass’ research points to PSAT scaling imperfections or irregularities as the more likely cause.

College Board’s goal is to make sure that PSAT scores from one year are comparable to PSAT scores in another year. It has not always met that goal. It faced a more difficult task than usual for the October 2015 and 2016 PSATs, because the scales were in flux and several PSAT problems had to be discarded as invalid. The fact that 46 of 50 states saw increased cutoffs and that PSAT scores increased for sophomore and juniors at essentially all ability levels means that student-specific factors such as increased preparation do not adequately explain the changes. The rise in cutoffs does not reflect an inexorable increase in scores. While cutoffs fluctuate from year-to-year, a longer view shows that there has not been a national trend toward higher scores. That claim cannot be made as universally at the state level. In-migration and economic growth help fuel competition for Semifinalist slots, which is why a state such as Texas has seen an upward trend over the last decade. Michigan is an example of where heightened attention to the PSAT can raise scores quickly. Even at the state level, though, it is unwise to focus on year-over-year changes as an indicator of future results.

There is relatively recent precedent for the sort of changes seen for the class of 2018. The class of 2012 had a 2-point increase in the Commended Student cutoff, just as happened this year. Only one state (Alaska) saw a lower cutoff, just as this year only one state (Rhode Island) saw a lower cutoff. Perhaps the most important takeaway, though, was that 2012 was an anomaly. It did not represent a shift in test performance but a one-year blip caused by imperfect scaling. The next year, the cutoffs fell, and they have since bounced around within expected ranges.

We won’t have a good answer to this question until scores from the October 2017 PSAT are released in December. Compass’ working hypothesis is that the results from the October 2016 PSAT were more accurate than those from the October 2015 PSAT. In 2016, College Board had more time to create the tests, millions more data points, and an official P/SAT scale that it set in May 2016 when the March SAT was graded.

Cutoffs vary across the country because the approximately 16,200 Semifinalists are allocated proportionally to states based on the total number of juniors in a class. The table at the top of the page shows how many Semifinalists from the class of 2016 were recognized in each state. A state’s cutoff is derived by finding the score that will produce, as closely as possible, the targeted number of Semifinalists. Students in any given state are competing only against fellow residents. The test is national, the competition is local.

Most teachers and counselors can point to a class of students that just seemed to have more award winners, more college admittances, or more star writers or athletes. Each year we see schools that make giant leaps from 20 Semifinalists to 35 (or the reverse). The smallest states have between 20 and 80 Semifinalists annually. Virginia’s magnet Thomas Jefferson High School for Science and Technology had more Semifinalists in the class of 2018 (145) than 18 states and more than the smallest 4 states combined. A “special class” can easily shift a small state’s cutoff.

Also, there is no such thing as a 220.427 cutoff – it must be all or nothing at 220 or 221. This means that even larger states can see swings based only on small chance effects.

It is not your imagination. While approximately the same number of students take the PSAT each year as take the SAT, there are crucial differences. Every student takes one of two PSAT/NMSQT forms on one of two dates in October (technically, there is a third, “alternate,” form and date). SATs have more dates, more forms, and students take and retake them throughout the year. The relative homogeneity of the PSAT means that it is highly susceptible to shifts, as there is no averaging out of differences. The size and direction of these shifts, though, cannot be predicted in advance. If they could be, College Board would take steps to prevent them.
