Is C-testing superior to cloze?

Several recent studies have suggested C-testing to be a highly valid and reliable measure of general language proficiency avoiding the problems with cloze testing. This study investigates the feasibility of the procedure with native and non-native speakers of English. Results of 20 C-tests constructed with different ratio and/or deletion start are analysed and discussed. The findings of the study refute the claims on C-testing. The implications of the findings are also discussed.
