About the 15m PACER Test
The Progressive Aerobic Cardiovascular Endurance Run (PACER) test is a version of the Beep Test, and is part of the FitnessGram and Brockport test batteries. This 15 meter version is the shorter alternative for those who do not have the space to conduct the 20m PACER, and also the choice for 2nd and 3rd grade students. Participants run back and forth over 15m, at speeds which increase approximately every minute.
Test Equipment and Setup
Equipment required: Flat non-slip surface, marking cones, up to 20m measuring tape, PACER test cd, cd player, recording sheets.
Pre-test: Explain the test procedures to the subject. Perform screening of health risks and obtain informed consent. Prepare forms and record basic information such as age, height, body weight, gender and test conditions (indoors/outdoors, weather, running surface). Measure and mark out the course. Perform a standard warm-up. See more details of pre-test procedures.
Test Procedure
Procedure: Two lines are marked out 15 meters apart. The test involves continuous running between the two lines in time to recorded beeps (see details of 15m PACER test levels and speeds). The time between recorded beeps decreases each minute (level) requiring an increase in pace. The speeds are the same as for the 20m PACER - the initial speed is 8.0km/hr, which increases to 9.0 km/hr then by 0.5km/hr each level (approximately every minute). The students continue until they are unable to keep pace with the beeps. They receive a warning the first time they are short of the turning line, and are removed from the test for the second infringement.

Scoring and Results
Scoring: The score is the total number of shuttles reached before the student was unable to keep up with the recording. The test scores can be entered into the FitnessGram software for analysis. To enter the scores into the FitnessGram software there is a conversion chart to convert results from the 15m PACER to a 20m equivalent score.
Target Population and Suitability
Target population: The test is suitable for sports teams and school groups of all ages, but not for people in which a maximal exercise test could be considered dangerous.
Test Reliability and Validity
Reliability: Reliability would depend on how strictly the test is run, and the practice allowed for the participants. Several practice trials would be ideal.
Advantages of the 15m PACER Test
Advantages: This shorter version is handy for those with limited indoor spaces. Large groups of children can perform this test all at once for minimal costs. Also, the test continues to maximum effort unlike many other tests of endurance capacity.
Disadvantages and Limitations
Disadvantages: Practice and motivation levels can influence the score attained, and the scoring can be subjective. As the test is usually conducted outside, the environmental conditions can also affect the results.
Important Considerations
Comments:
- This test is a maximal test which requires a reasonable level of fitness - care must be taken with students who are sick, of poor fitness or elderly.
- The FitnessGram cd also provides the cadences for the curl-up and push-up portions of the test battery
Sport-Specific Applications
PACER Performance by Sport
According to research by Robert J. Wood, PhD in Exercise Physiology from the University of Western Australia and founder of Topend Sports, different sports require varying levels of aerobic capacity as measured by the PACER test:
Soccer: Elite youth players typically achieve 100+ laps (20m equivalent). The high aerobic demand of continuous running and sprinting requires exceptional cardiovascular fitness. Division I college programs often expect 80+ laps for males and 60+ for females.
Basketball: Good basketball players score 70-90 laps (20m equivalent). The intermittent high-intensity nature of basketball requires both aerobic and anaerobic fitness. Guards typically score higher than post players due to greater court coverage.
Cross-Country Running: Elite runners regularly exceed 120+ laps. The PACER test correlates strongly with 5k race performance and provides an excellent measure of aerobic capacity for distance runners.
American Football: Scores vary significantly by position. Skill positions (running backs, receivers, defensive backs) average 70-85 laps, while linemen typically score 40-60 laps. Position-specific aerobic demands vary considerably.
Wrestling: Competitive wrestlers score 75-95 laps. The repeated high-intensity efforts and short recovery periods in wrestling require strong aerobic conditioning to support anaerobic performance.
Improving Your PACER Score
Training Strategies for Athletes
Interval Training: The most effective method for improving PACER performance is high-intensity interval training. Example workout: 8 x 400m at 90% effort with 90 seconds recovery. Perform 2x weekly.
Shuttle Runs: Practice the test format itself. Run 6-10 shuttles at race pace, rest 2 minutes, repeat 4-6 times. This develops both physical and mental adaptation to the test demands.
Tempo Runs: Build aerobic base with 20-30 minute runs at "comfortably hard" pace (about 80-85% max heart rate). Perform 2x weekly on non-interval days.
Sport-Specific Conditioning: Integrate small-sided games, position-specific drills, and sport movements to develop the aerobic system while maintaining sport skills and movement patterns.
Progressive Overload: Gradually increase training volume and intensity over 6-8 weeks. Expect to see measurable improvement (10-20 more laps) with consistent training three times per week.
Frequently Asked Questions
How do I convert my 15m PACER score to 20m?
The 15m to 20m conversion uses the official FitnessGram formula which accounts for the increased frequency of turns in the 15m test. Generally, 15m laps convert at approximately a 0.63-0.67 ratio to 20m laps, varying by performance level. The calculator above performs this conversion automatically using validated formulas.
What is a good PACER score for my age?
Good scores vary significantly by age and gender. For males aged 14-18, reaching 75-85 laps (20m equivalent) is considered good, while 36-44 laps is good for females. Younger students (10-13) typically achieve 40-70 laps for boys and 25-40 for girls within the Healthy Fitness Zone. Elite athletes often exceed 100 laps.
How accurate is the VO₂max estimate from PACER?
Research by Mahar et al. (2006) shows the PACER test provides VO₂max estimates with a standard error of approximately ±6.5 ml/kg/min when using validated prediction equations. Accuracy is best when maximal effort is given. The equations used in this calculator account for age and gender to improve precision.
Is the 15m test harder than the 20m test?
The 15m test requires more frequent turns (every 15 meters instead of 20), which increases the anaerobic demand from deceleration and acceleration. However, research by McClain et al. (2006) found that when properly converted, both tests provide similar measures of aerobic capacity. Athletes with better agility may perform relatively better on the 15m version.
Do college coaches look at PACER scores?
Yes, many college coaches consider PACER or beep test scores as indicators of aerobic fitness during recruitment. Division I soccer programs often expect 80+ laps for males and 60+ for females. However, sport-specific skills, game performance, and other athletic attributes are typically weighted more heavily in recruitment decisions than a single fitness test score.
How often should I take the PACER test?
For tracking fitness progress, testing every 6-8 weeks is ideal. This allows sufficient time for physiological adaptations from training while providing regular feedback. Avoid testing more frequently than every 3-4 weeks, as the test is physically demanding and requires maximal effort. School-based programs typically test 2-3 times per academic year.
What should I do before taking the test?
Proper preparation includes: adequate sleep (7-9 hours) the night before, light meal 2-3 hours before testing, proper hydration throughout the day, and a thorough 10-15 minute warm-up including dynamic stretching and progressive running. Avoid heavy training the day before the test. Mental preparation and understanding the pacing strategy are equally important for optimal performance.
