Cloze test and C-test are reading comprehension tests that assess a test-taker's ability to understand text with missing words. In a cloze test, words are deleted from a passage at regular intervals, usually every 5th-8th word. In a C-test, the second half of every second word in a passage is deleted. Both tests are easy to construct and score but a C-test has lower face validity due to more blanks. While cloze tests leave the first sentence intact, C-tests delete words throughout the entire passage.
