Section pre-equating (SPE) is a new method for equating tests that was developed in response to test disclosure legislation. It is designed to equate a new test to an old test prior to the actual use of the new test, and makes extensive use of experimental sections of a testing instrument. This paper extends the theory behind SPE to allow for the effects of practice on both the old and the new tests, and gives a unified and generalized account of SPE. (23pp.)
