Table of Specification
The purpose of a Table of Specifications is to identify the achievement domains being measured and to ensure that a fair and representative sample of questions appear on the test. Teachers cannot measure every topic or objective and cannot ask every question they might wish to ask. A Table of Specifications allows the teacher to construct a test which focuses on the key areas and weights those different areas based on their importance. A Table of Specifications provides the teacher with evidence that a test has content validity, that it covers what should be covered.
A table of specifications is simply a test plan. The objectives covered are on the left with levels of learning2 across the top. The numbers, such as 2 at the Remember level for each objective, indicate how many items the instructor plans to include on the test for each objective and level of learning.
