Test Quality
Whether standard physical fitness tests or self-made fitness tests are employed they should always conform to several quality standards:

Validity
This refers to the degree that a test measures what it's supposed to. This is usually straightforward - a distance run for example would not be a valid measure of explosive power. Sometimes the distinction maybe a little less clear.

Reliability
This refers to the consistency or repeatability of a fitness test. If an individual does not change his or her athletic ability then a reliable test, repeated twice will show no difference. The only variable the test should measure is the one it is designed to.
