A system for computer-based testing for producing a test and delivering the test to an examinee includes a test driver that has an executable code that controls the test driver, a storage device that has a plurality of storage locations, which store the test definition language as a plurality of segments, and a validation expansion module that validates at least one of the plurality of segments of the test definition language and writes the at least one of the plurality of segments directly to at least one of the plurality of storage locations in the storage device. A method instantiating a validation expansion module during a test production cycle and loading at least one of the plurality of segments of the test definition language into the validation expansion module from a source file. The method also includes validating the at least one of the plurality of segments from the source file and unloading the at least one of the plurality of segments from the validation expansion module into at least one of a plurality of storage elements within a storage device. The method of computer-based testing includes instantiating the validation expansion module during a test delivery cycle, providing to the validation expansion module the at least one of the plurality of storage elements, and loading the at least one of the plurality of segments of the test definition language from the at least one of the plurality of storage elements into the validation expansion module during a test delivery cycle.
