Content validity checks to be sure the information being tested on actually matches what should be covered on the test.
Concurrent criterion-related validity uses two tests that cover the same information to determine the validity evidence of the test.
Predictive criterion-related validity determines how well the tests predicts some future behavior of the students (1).
Test-retest gives a test twice and then compares the results to check for reliability.
Internal consistency splits the test in half to determine correlation between the two halves.
Alternatives are when two equal tests have large inconsistencies in scores which shows the tests could possibly be ...
This solution defines the concepts of validity and reliability and describes how they are important in evaluating assessment tests administered to preschool and school-age children.
