A primer-test centered equating method for setting cut-off scores.

Area of Science:

• Exercise Physiology
• Biostatistics
• Educational Measurement

Background:

• Field tests for aerobic capacity often show inconsistent student classification.
• Standardized fitness assessments are crucial for accurate health evaluations.

Purpose of the Study:

• To evaluate a novel test equating method for harmonizing field test results.
• To establish an equivalent relationship between the Progressive Aerobic Cardiovascular Endurance Run (PACER) and mile run (MR).

Main Methods:

• Utilized Kernel equating to establish PACER-MR score equivalency.
• Derived mile run PACER equated (MR PEQ) scores to predict maximal oxygen uptake (VO2max).
• Compared MR PEQ predictions and classifications against measured VO2max and original field test data.

Main Results:

• The MR PEQ scores demonstrated accurate conversion and functioned similarly to original MR scores.
• MR PEQ and original MR scores outperformed PACER in predicting VO2max and classifying students.
• Cross-validation using middle school data generally supported the findings.

Conclusions:

• The proposed test equating method is accurate and effective for scaling new field tests.
• This approach allows for consistent classification across different aerobic fitness field tests.
• The method facilitates the determination of reliable cut-off scores for fitness zones.
