چکیده    Multiple choice questions (mcqs) are one of the most popular tools to evaluate learning and knowledge in higher education. nowadays,there are a few indices to measure reliability and validity of these questions,for instance,to check the difficulty of a particular question (item) or the ability to discriminate from less to more knowledge. in this work two new indices have been constructed: (i) the no answer index measures the relationship between the number of errors and the number of no answers; (ii) the homogeneity index measures homogeneity of the wrong responses (distractors). the indices are based on the lack-of-fit statistic,whose distribution is approximated by a chi-square distribution for a large number of errors. an algorithm combining several traditional and new indices has been developed to refine continuously a database of mcqs. the final objective of this work is the classification of mcqs from a large database of items in order to produce an automated-supervised system of generating tests with specific characteristics,such as more or less difficulty or capacity of discriminating knowledge of the topic. © 2014 mariano amo-salas et al.
