USPSA classifiers in 60 seconds (BLUF)

• What it is: A classifier is a short, standardized course of fire you shoot at a local match. Your raw score becomes a hit factor (points ÷ time), and that hit factor is compared against USPSA’s benchmark for that stage to produce a percentage.
• How you get classified: You need four valid scores from four different classifiers in a division. After that, your class is set by the best 6 of your most recent 8 unique classifier percentages.
• The classes: Grand Master (95%+), Master, A, B, C, D — each division is scored separately, so you can be A-class in Production and C-class in Open.
• What changed in 2025: USPSA removed the old B/C/D flags, started averaging same-day attempts, and released the new 25-Series classifier stages. More on that below.
• The fastest way to move up: practice the exact mechanics a classifier measures — draw, splits, reloads — with a free Airsoft Shot Timer app between matches.

If you’ve shot a couple of USPSA matches, you’ve already run into classifiers — those short, oddly specific stages where everyone suddenly gets quiet and serious. And if you’ve ever logged into uspsa.org and stared at a wall of percentages, division codes and three-digit stage numbers, you’ve probably also wondered what any of it actually means for you. This guide unpacks the whole system in plain language: what a classifier is, how a stopwatch number becomes a letter grade, what the 2025 overhaul changed, and how to nudge your percentage upward without gaming it.

IPSC Classification Explained in 60 Seconds (BLUF)

Short answer: IPSC ranks shooters into six classes — Grand Master (95%+), Master (85–94.9%), A (75–84.9%), B (60–74.9%), C (40–59.9%), and D (under 40%). The percentage is calculated against the highest hit factor ever recorded on a standardized Classifier Stage (CLS). You need a minimum of four CLS scores to get an initial class, and after that your classification is recalculated from the best 4 of your most recent 8 results. To keep your class active, you must shoot at least one classifier match or two CLS stages each calendar year, and your class is division-specific — being an A-class in Production doesn’t make you A-class in Open.
