In the weighted airman promotion system (WAPS), time in grade (TIG) is computed at the rate of

• A. One-half point per month in grade up to 20 years
• B. One-half point per month in grade up to 10 years
• C. One-fourth point per month in grade up to 10 years
• D. One-fourth point per month in grade up to 20 years

Answer: (B)

In WAPS, time in grade is credited to your promotion score at a rate of one-half point for every month you are in the current grade, but this credit stops after ten years in that grade. So you can accumulate up to 60 TIG points (0.5 × 12 months × 10 years). After reaching ten years, additional time in grade doesn’t add more TIG points.

That’s why the statement with a half-point per month up to ten years is the correct description. The other options either state the wrong rate or extend the cap beyond ten years, which doesn’t align with how TIG is calculated in WAPS. For a quick check, if you’re in grade for 7 years, TIG contributes 7 × 12 × 0.5 = 42 points to your promotion score.
