1A sport scientist computes Cohen's d = 0.25 for the effect of a new plyometric block on countermovement jump height. Using Cohen's conventional benchmarks, how should this effect size be interpreted?
A.Trivial / no effect
B.Moderate effect
C.Small effect
D.Large effect
Explanation: Cohen's d standardizes the mean difference by the pooled standard deviation. Conventional benchmarks classify d ~0.20 as small, ~0.50 as moderate, and ~0.80 as large. A value of 0.25 is therefore a small effect, although in elite sport even small standardized changes can be practically meaningful relative to the smallest worthwhile change.
2Which statistic best quantifies the relative consistency of repeated measurements and is commonly used to judge the reliability of a performance test?
A.Pearson product-moment correlation
B.Independent-samples t-test
C.Intraclass correlation coefficient (ICC)
D.Coefficient of determination (r-squared)
Explanation: The intraclass correlation coefficient (ICC) compares between-subject variance to total variance and is the preferred index of relative reliability for repeated measures because it accounts for systematic and random error. ICC values above 0.75 are generally considered good, and above 0.90 excellent for many performance tests.
3A coach reports that an athlete's sprint time improved by 0.04 s, but the typical error of the test is 0.06 s. What is the most defensible conclusion?
A.The change is within measurement noise and cannot be confidently called real
B.The change is a true performance improvement
C.The test is invalid
D.The athlete should be deselected
Explanation: When a observed change is smaller than the typical error (the within-subject standard deviation across trials), it cannot be confidently distinguished from measurement noise. The sport scientist should treat the 0.04 s change as non-meaningful until it exceeds the typical error or the smallest worthwhile change.
4The smallest worthwhile change (SWC) for team-sport monitoring is frequently estimated as which fraction of the between-athlete standard deviation?
A.0.2 x between-athlete SD
B.1.0 x between-athlete SD
C.2.0 x between-athlete SD
D.0.6 x the mean
Explanation: A common default for the smallest worthwhile change is 0.2 multiplied by the between-athlete standard deviation, derived from Cohen's small effect size. This benchmark helps practitioners decide whether an observed change in a monitoring variable is practically important relative to noise.
5A p-value of 0.03 from a two-tailed test with alpha set at 0.05 indicates which of the following?
A.The null hypothesis is proven true
B.The result is statistically significant at the chosen alpha level
C.There is a 3% chance the alternative hypothesis is false
D.The effect is practically important
Explanation: A p-value of 0.03 is less than the alpha of 0.05, so the result is statistically significant and the null hypothesis is rejected. Statistical significance does not establish practical importance, which requires an effect size and reference to the smallest worthwhile change.
6In assessing a force plate test, the coefficient of variation (CV) is used primarily to express which property?
A.Concurrent validity
B.Statistical power
C.Construct validity
D.Relative within-subject variability as a percentage
Explanation: The coefficient of variation expresses the typical error as a percentage of the mean, providing a unit-free measure of relative within-subject variability. Lower CV values (often <5% for many force-plate metrics) indicate more reliable measurement and a more sensitive test for detecting change.
7Which assessment technology directly measures barbell or implement velocity to enable velocity-based training prescription?
A.Heart-rate monitor
B.Skinfold caliper
C.Linear position transducer
D.Doubly labeled water
Explanation: A linear position transducer (LPT) measures displacement over time of a barbell or athlete, allowing calculation of velocity and power. These data underpin velocity-based training, where load is adjusted to maintain target movement velocities such as the minimal velocity threshold.
8An acute:chronic workload ratio (ACWR) of 1.6 calculated with a 7-day acute and 28-day chronic window most likely indicates what?
A.A rapid spike in workload associated with elevated injury risk
B.A protective 'sweet spot' workload
C.Detraining due to insufficient load
D.An invalid calculation
Explanation: An ACWR around 0.8-1.3 is often described as the relative 'sweet spot,' whereas ratios above ~1.5 reflect a sharp spike in acute load relative to the chronic baseline and have been associated with increased injury risk in several team-sport studies. The sport scientist would flag this athlete for load review.
9GPS units used for athlete tracking in field sports primarily provide which category of data?
A.Internal physiological load
B.External locomotor load such as distance and speed
C.Muscle activation amplitude
D.Joint angular kinematics
Explanation: GPS (and local positioning systems) capture external load: total distance, speed zones, accelerations, and decelerations. External load reflects the work performed, while internal load (e.g., heart rate, RPE) reflects the athlete's physiological response to that work.
10Heart-rate variability (HRV), often expressed as the natural log of RMSSD, is most commonly used by sport scientists as a marker of what?
A.Maximal aerobic power
B.Bone mineral density
C.Anaerobic threshold
D.Autonomic nervous system status and readiness/recovery
Explanation: HRV indexed by lnRMSSD reflects parasympathetic (vagal) modulation of heart rate. Trends in HRV are used to infer autonomic recovery and training readiness, with suppressed values often indicating accumulated fatigue or incomplete recovery.

Frequently Asked Questions

What are the eligibility requirements for the NSCA CPSS exam?

You must meet one of three pathways: a bachelor's degree in sport science or a related field plus 3 years of full-time professional experience; a master's degree plus 12 weeks (480 hours) of applied experience; or a doctorate degree. Candidates also submit a non-refundable $25 application fee with registration, and the exam fee is $340 for NSCA members or $475 for non-members.

How hard is the CPSS exam and what is the pass rate?

The CPSS is an advanced exam. NSCA's 2025 exam report shows the CPSS was administered to 339 candidates with a 68% pass rate. It is challenging because roughly a third of questions cover the research process (design, statistics, reliability and validity), and many items are scenario-based. With focused preparation on research methods and assessment technology, most qualified candidates can pass.

What is the format of the CPSS exam?

The CPSS exam has 115 items total: 100 scored questions plus 15 unscored pretest questions, with 165 minutes to complete it. It uses a combination of case study-based items (athlete scenarios) and independent items, including research-review questions where you critique study findings. A scaled score of 70 or higher is required to pass.

How does the CPSS use case studies and research-review questions?

Many CPSS items present an athlete monitoring scenario or a peer-reviewed study excerpt and ask you to interpret data such as effect sizes, p-values, ICC, coefficient of variation, the smallest worthwhile change, or the acute:chronic workload ratio. You must apply research and assessment principles to make a defensible practical decision rather than recall isolated facts.

How long should I study for the CPSS exam?

Plan for roughly 80-120 hours over 12-20 weeks, weighted toward the research process and assessment technology domains, which together make up over half the exam. Practice interpreting statistics and athlete-monitoring data with realistic case-style questions, and review NSCA's official CPSS exam description and content outline before scheduling.
