Regardless of whether the assessor changes during a test, or multiple assessors are observing one performer, the same result should be garnished from the test. An indicator of a reliable test is the absence of anomalies. The less variation there is between each result recorded, the more reliable we can say a test is. The grip dynamometer test is reliable as it has simple processes and little opportunity for human error to impact results. The multi-stage fitness test has multiple variables and processes that can change between each trial, reducing its reliability.Validity The idea that the quality of a test result is directly proportionate to the quality of the component of fitness being tested. Only muscular strength determines the score recorded in the grip dynamometer test. Multiple variables could influence the total time recorded in the Illinois agility test. The most valid tests are when just one component of fitness has any impact on the test result.Practicality This is how quick and easy a test is to set up and complete. If an assessor can learn the procedures and educate the performer about them quickly, a test can be said to be practical. For a test to be practical, the equipment should be cheap, accessible and widely available. The wider the range of locations a test can be completed in, and the shorter amount of time it takes, the more practical a test is. The 1 minute sit up test is practical as it requires minimal equipment and can be completed quickly. The 35m Sprint test requires speed gates and a non-slip surface of 45m.
