Question and answer
Q: what do you do/what does your school to ensure content validity of your periodic test
A: For example, suppose a test purports to measure mathematical knowledge and skills (step 1). [ Test users should decide what forms of consistency are most important (e.g., inter-rater agreement, stability), and then determine whether the test scores have reliability values greater than or equal to 0.80 (step 2). If the test has reasonable evidence of reliability, users should decide which forms
of evidence are most salient. Achievement tests should have substantial evidence of test content (e.g., items should represent domains identified by the National Council of Teachers of Mathematics), internal structure (e.g., items purporting to measure common subdomains actually relate to each other), and relationships to other variables (e.g., the test correlates with other math tests). If the test also claims intended consequences (e.g., it will help plan educational interventions), then evidence showing how test scores enhance intervention selection, implementation, or outcomes should be provided. It should be noted that some domains (e.g., content) are more important than other domains (e.g., response processes). Finally, users should assess the evidence provided to judge the degree to which evidence supports the claims. Test reviews can be helpful, but test standards mandate that test users are personally responsible for ensuring that the tests they use have appropriate supporting evidence. Read more ; ]
