This invention is directed to an optical mark sensing device known as a mark read scanner for reading marks on a form. This scanner is a stand-alone device that has an internal micro-controller with the controlling software therein. An external personal computer is not required to operate the scanner in its intended manner. "Graphic switches" are printed on the form to define the characteristics of a form to be scanned. The expense of replacing the internal program of a scanner when a user requests a variation of a test form that had not been pre-programmed into the original specifications of the scanner is eliminated.

An automated system and method for creating a test form that conforms to predetermined content specifications (the blueprint) and has a desired statistical profile (target statistics). The algorithm divides the test-construction problem into two phases: a content-matching phase that is followed by a statistical-matching phase. In these phases, (1) a structural skeleton is sought that fits the blueprint; and (2) a search is made among the set of all possible tests that could be created from a pool of items for at least one test that matches the desired target statistics. The algorithm performs the statistical matching in the second phase without upsetting the content match that was attained in the first phase. This is possible because the content matching takes place using content specifications that match a number of different items or sets of items rather than specific items or sets of items.
