Calculating National Merit Score?

I just took the PSAT recently, and I'm curious about how National Merit scores are calculated. Can anyone explain how my overall score, including this separate selection index I've heard about, is computed? Is it different from the PSAT scores?

Calculating your National Merit Selection Index (NMSI), which determines your eligibility for the National Merit Scholarship Program, is relatively simple. Your NMSI is based on your PSAT scores, but it's not the same as your overall PSAT score.

To calculate your NMSI, follow these steps:

1. Find your PSAT/NMSQT scores: Look at your score report for your Reading, Writing and Language, and Math test scores. These are on a scale of 8 to 38.

2. Add your test scores: Add the scores from the Reading, Writing and Language, and Math sections together.

Example: Reading (30) + Writing and Language (35) + Math (32) = 97

3. Multiply by 2: Multiply the sum of your test scores by 2.

Example: 97 x 2 = 194 NMSI

In this example, your National Merit Selection Index would be 194. This index is used to determine which students qualify as Commended Scholars, Semifinalists, and Finalists in the National Merit Scholarship Program. The cutoff scores for National Merit status vary from year to year and state to state. Generally, NMSI scores above 190-200 are competitive for earning some level of recognition, but keep in mind that the exact cutoffs are subject to change.

It's important to note that your overall PSAT score is not directly used for determining National Merit eligibility. However, your PSAT score can indicate your chances of performing well on the SAT, and it's a helpful tool for identifying areas where you may want to focus your test prep efforts.
