Abstract

The purpose of the research is to investigate using "none of the above" (NOTA) option on psychometric properties of multiple choice tests (MC): Item difficulty, item discrimination and test reliabilty. Using two test forms symetrical in content, consisted of (25) MC items with four options, the first form items had real options, the second form was built by replacing the key option in (13) items, and one of the distractores in the (12) items left, by NOTA option. These formes were applied on (240) indiveduals. The research results indicate that the existence of the NOTA option make the test items more difficult, while it presence does not affect item discrimination nor test reliability.
