Sports performance testing is one of the most common and important measures used in sport science. Performance testing protocols must have high reliability to ensure any changes are not due to measurement error or inter-individual differences. High validity is also important to ensure test performance reflects true performance. Time-trial…

Argues that if a testing situation is not similar to situations in which a child regularly performs linguistically, the test's ecological validity is compromised and its results must be viewed skeptically. (FL)

Fair, valid, and reliable measurement of dependent variables is a concern in personnel evaluation studies. Performance tests, that is, job or work sample tests, situational tests, and job learning or trainability tests, are being used with increasing frequency as measurement techniques capable of meeting these needs. The three categories of…

Distance running tests evaluate a unique physical activity that is an important component of many other physical tasks. Factor analytic studies have clearly shown that distance running tests assess underlying abilities and physiological capacities that are different from those assessed by runs of shorter duration.

Suggests that language testing should be more performance-based and realigned with a current and richer understanding of the language teaching and learning processes. This kind of testing has questionable validity until a wide range of variables are successfully defined and delimited. (CB)
