Author systematized and analyzed methods and techniques of evaluation of one of the main indicators of quality of computerized testing system (CTS) - reliability index; given the traditional metrics for evaluation of different types of reliability test space are studied and improvements in terms of features of the scale, which evaluates the performance reliability of the test space CTS. The dynamics of changes of the uncertainty of reliability during monitoring of the system allows to predict the qualitative characteristics of the CTS on the basis of a predetermined volume of the test space.
Keywords: computerized testing system, the test space, reliability test space, uncertainty
