1. What is a PSAT Selection Index?

Definition: The Selection Index is a score used to determine eligibility for the National Merit Scholarship Program.

Purpose: It combines your Reading, Writing, and Math scores into a single number between 48 and 228.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( SI \) — Selection Index (48-228)
• \( R \) — Reading score (0-38)
• \( W \) — Writing score (0-38)
• \( M \) — Math score (0-38)

Explanation: The sum of Reading and Writing scores is doubled and added to the Math score.

3. Importance of the Selection Index

Details: This score determines National Merit Scholarship qualification. The cutoff varies by state but typically ranges from 207-223.

4. Using the Calculator

Tips: Enter your section scores from your PSAT/NMSQT report. Each score should be between 0-38.
