Standardized tests, and records of classroom performance on less formal tests are essential for supplying much of the data upon which these decisions are based. Classroom instruction depends upon a large support network. That network needs information if an adequate support level is to be maintained. Tests in various forms can supply that information. Various types of tests can be employed when measuring how effectively teaching impacts student learning.
Standardized tests are particularly useful at all three levels.
These tests can be used in norm, criterion and objective-referenced modes. Tests written within the district for large-scale use can also supply information focused specifically on unique, local aspects of educational programs. There is a gap between what teachers and administrators think, and what those who write about them say that they think about the value of testing. Those who are more experienced and who have had measurement training and experience in administering tests show greater support for the use of them than do those who are less experienced and less knowledgeable. Students feel that frequent testing helps them retain more content, reduces test anxiety, and aids their own monitoring of their progress.
