Generate cloze (fill in the blank) exercises from any passage. Choose interval or random blanking and difficulty.
Use cloze-test generation for classroom comprehension exercises, language-learning drills, vocabulary practice, and reading-research studies. The cloze procedure is the gold standard against which readability formulas were originally validated.
Cloze tests are an assessment tool, not a metric. Pair the generator with a readability score (Flesch or Dale–Chall) to choose appropriate source material before generating items.
A cloze test removes words from a passage and asks readers to fill them in. It is used to measure both comprehension and vocabulary.
You can blank every Nth word (the classic format) or randomly blank a percentage of words. Optionally exclude capitalised words to avoid blanking proper nouns.
The answer key is generated below the passage so you can print and use it in class.
A cloze test removes words from a passage and asks readers to fill them in. It measures both vocabulary and comprehension.
Interval blanking (every Nth word) is the classic format and easier to score. Random blanking lets you target specific word types.
Classic cloze readability tests delete every fifth, sixth, or seventh word; every seventh is gentler and every fifth is harder. For vocabulary practice, targeting specific word types instead of a fixed interval is often more useful.
The strict method counts only the exact original word as correct, while the acceptable-word method also credits reasonable synonyms. Exact scoring is standard for comparing readability across passages.
Input
"The cat sat on the mat." with every 3rd word blanked.
Output
"The cat ___ on ___ mat."
Cloze tests measure both reading comprehension and vocabulary, since readers must use surrounding context to recover the missing word.
