PACER (Beep Test): Males, Age 12
The PACER (Progressive Aerobic Cardiovascular Endurance Run), also known as the beep test, bleep test, or 20-metre shuttle run, is the most widely used field test of cardiorespiratory fitness in children and adolescents. Participants run back and forth along a 20-metre course, keeping pace with audio beeps that get progressively faster each minute. The test ends when the participant can no longer keep pace for two consecutive laps. Norms on this page are drawn from Tomkinson et al. 2017, the largest international 20m shuttle run normative study, covering 1,142,026 performances from 50 countries in children and adolescents aged 9 to 17.

Percentile Distribution (laps)
| Percentile | Value (laps) | Rating |
|---|---|---|
| 5th | 9 | Poor |
| 25th | 27 | Below average |
| 50th | 39 | Average |
| 75th | 54 | Above average |

What these numbers mean for males aged 12
A score around 39 laps is typical (50th percentile) for males in this age group. Scores above about 54 laps fall near the 75th percentile or higher, indicating above-average performance. Scores below about 27 laps fall near the 25th percentile, about 75% of the reference population scored higher.
Percentiles show how common a value is, not whether it is healthy.
