In the current study, the validity of C-Test is investigated using the construct identification approach. Based on construct identification approach, the factors which are deemed to affect item difficulty in C-Test items were identified. To this aim, 11 factors were selected to enter into Linear Logistic Testing Model (LLTM) analysis to…

In this paper we tried to demonstrate the validity of C-Test using construct identification approach. In this approach to construct validation the factors which contribute to item difficulty are identified. The assumption is that the factors which make items difficult are actually the construct underlying the test. For the purposes of this study,…
