PSAT Grading Scale

I took the PSAT recently and I'm trying to understand how it's graded. Like, how do they translate your raw scores into the scaled scores? Would love to get some insights on this!

The PSAT works on a scoring system that has two sections - Math and Evidence-Based Reading and Writing. As for figuring out the scores, each section is scored on a scale of 160 to 760, making the highest possible score 1520. The process of equating raw scores into scaled scores involves a couple of steps.

To start, a raw score is calculated based on the number of questions you answer correctly. The PSAT doesn't have a penalty for incorrect answers, so essentially, your raw score is the number of questions you answered correctly on the test.

Once the raw score is in hand, it's converted into what's called a 'scaled score'. This is done using an equating process by the College Board, which adjusts for minor differences in the difficulty levels of different test forms. The aim of this process is to ensure that a score of 600 from one test signifies the same level of ability as a score of 600 from another test, even if one test was slightly more or less challenging compared to the other.

Remember that the PSAT, like the SAT, evaluates your skills in these categories: reading; writing and language; and math (both with and without a calculator). It's always a good idea to review your test results in detail to understand your strengths and areas for improvement in each of these categories.

Additionally, with the National Merit Scholarship Program, it's crucial to note that PSAT scores are also converted into Selection Index scores (ranging from 48 to 228), which determines eligibility.

I know it seems quite technical, but I hope this brings some clarity on how PSAT grading works. Always remember that these scores are just a benchmark to help you understand where you stand academically, and they provide a solid starting point to further prepare for future exams, like the SAT.
