This paper describes a procedure for automated test forms assembly based on Classical Test Theory (CTT). The procedure uses stratified random content sampling and test form pre-equating to ensure both content and psychometric equivalence in generating virtually unlimited parallel forms. The procedure extends the usefulness of CTT in automated test form construction, yielding classical item statistics based on representative sample distributions and pre-equated test forms with known psychometric characteristics. A rationale for the procedure is presented followed by an example application and discussion of psychometric considerations related to its use.
