Definitions for "equating"
A statistical procedure that puts the raw scores of newly introduced forms of a test on a continuing scale and compensates for variations in difficulty among various forms of the test. Equating often involves comparison of the performance of an old and a new group of candidates on the same test material. Sometimes a random sample of new test-takers takes an entire old form of the test; or a representative sample of material from an old form may be added to a new form.
