Why the spelling is quiz, and how to practice it
Most people typing is it quiz or quizz into a search bar are checking one word before a deadline, and the answer is quiz, with one z. Quizz is a common misspelling, and standard dictionaries and style guides use quiz for the noun and the verb.
- Quiz is the standard spelling for the noun and the verb.
- Plurals and past tense double the z: quizzes, quizzed, quizzing.
- Quizzical keeps the double z because it comes from the same root.
- Practicing on your own notes beats memorizing spelling lists for exams.

The same rule shows up in the other forms. The plural is quizzes and the past tense is quizzed, because the final z doubles before a suffix that starts with e or i. Learning these forms once makes them easy to spell correctly in essays and emails.
For actual exam prep, reading a list of spelling rules is less useful than answering questions on your own material. DeckOwl builds a quiz from your notes so you test recall first and check the explanations after.

Frequently asked questions
Is quizz ever correct spelling?

How do you spell the plural and past tense of quiz?
The plural is quizzes and the past tense is quizzed, since the final z doubles before an added es, ed or ing. Quizzing follows the same pattern for the present participle.
