PACER Test Guide

The PACER test is a running test schools in the United States use to check how fit a student's heart and lungs are. Short for Progressive Aerobic Cardiovascular Endurance Run, it's the same shuttle run as the beep test used elsewhere in the world: run back and forth between two lines spaced 20 meters apart, keeping pace with a beep that gets faster every level.

PE teachers run it as part of FitnessGram, the national youth fitness assessment developed by the Cooper Institute and used in thousands of US schools. Most students take it once or twice a year in gym class, and the result becomes part of a fitness report sent home alongside push-up and flexibility scores. It isn't a test you pass or fail on the spot.

There are two official distances: the standard 20-meter version most schools use, and a 15-meter version built for gyms too small to fit a 20m course (more on that below). Both measure the same thing: aerobic capacity, meaning how well your body delivers oxygen to working muscles during sustained effort. Scores convert into an estimated VO₂ max using the Léger et al. (1988) equation, the same formula sports scientists use for the international beep test.

The 20-meter PACER test has 20 levels. If you completed every shuttle in every level, you'd finish 231 laps, the highest score the test allows. Almost nobody gets there. A fit high schooler often lands somewhere between 60 and 100 laps, while a college athlete might push past 120.

Whether a number is "good" depends entirely on age and sex. See the FitnessGram Healthy Fitness Zone tables below for what counts as a healthy range at each age.

If you took the PACER test in a US school any time in the last twenty years, you probably remember the voice. Before the beeps start, the official recording opens with a spoken introduction explaining the rules, and one line in particular stuck with an entire generation: "The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues."

That sentence became one of the most recognized copypasta phrases on the internet. In early 2016, Vine creators started dubbing the recording over completely unrelated footage: a baby's supposed first words, a dying grandfather's last words, a piano recital gone wrong. The clips spread fast, and by the end of the year "the FitnessGram Pacer Test" was shorthand for a very specific kind of absurd comedy. Know Your Meme has the fuller history of how it spread, if you want the deep cut.

The Cooper Institute, which owns the test and the recording, didn't fight the joke. It leaned into it, teaming up with Hip Hop Public Health to release official PACER test remixes, turning the same instructions into tracks kids could actually work out to.

We're not going to reprint the script here. It's the Cooper Institute's recorded work, not ours to republish, and the meme has already done more with it than a copy-paste ever could.

Not every gym has room for a 20-meter shuttle run. FitnessGram also publishes a 15-meter version of the PACER test for smaller spaces, using the same progressive speeds over a shorter running distance. Because each lap covers less ground, you rack up more laps on the 15m course to hit the same fitness level, so school PE departments that use the 15m format publish look-up charts that convert 15m lap counts into their 20m equivalents, so scores stay comparable across schools.

If you want to try a shorter shuttle run yourself, we also have a 15m shuttle test mode built around the UK's Job Related Fitness Test (JRFT) format, which uses the same 15-meter distance.
