How a grammar diagnostic quiz works

A diagnostic quiz only helps if it tests the grammar your class actually covered, so a generic worksheet from the internet often misses the point. Upload your own material and DeckOwl writes a grammar diagnostic quiz that targets the rules, examples and terms in that document.

Questions are drawn only from the material you upload
Multiple-choice, true/false and short answer formats
Explanations for each answer to show why it is right or wrong
Free plan includes 3 generations per month, with no credit card needed to start

Example grammar diagnostic quiz questions

Which sentence uses the correct verb form? (a) She have finished the report. (b) She has finished the report.b. 'Has' agrees with the singular subject 'she', so the present perfect uses 'has finished'.

True or false: A comma splice joins two independent clauses using only a comma.True. Two complete sentences need a period, a semicolon, or a comma with a coordinating conjunction.

Choose the correct pronoun: Between you and ___, the decision is fair.me. 'Between' is a preposition, so it takes the object pronoun 'me'.

Identify the subject of this sentence: Under the old bridge, the children found a coin.The children. The subject names who performs the action, and 'under the old bridge' is a prepositional phrase.

Which verb completes the sentence? Neither of the reports ___ accurate. (a) were (b) wasb. 'Neither' is singular in this sense, so it takes the singular verb 'was'.

How it works

Upload your lesson

Add the grammar notes, slides or handout you want to check. Photos of printed pages are read with text recognition.

Choose a question type

Pick multiple-choice, true/false or short answer, then generate the quiz.

Review and run it

Check the questions, then give the quiz to students or take it yourself to see where the gaps are.

Good diagnostic questions separate students who understand a rule from those who only recognize it. Multiple-choice items can show which error a student is making, while true/false items catch misconceptions quickly. Explanations after each answer turn the quiz into a short lesson.

Run the quiz at the start of a unit to find weak spots, then again after review to see what improved. Because the questions come from your own notes, the results line up with what you are teaching.

Frequently asked questions

What grammar topics should a diagnostic quiz cover?

Start with the rules you taught in the unit, such as subject-verb agreement, pronoun case, punctuation and verb tense. A diagnostic works best when each question checks one rule clearly.

How many questions make a useful grammar diagnostic?

Around 10 to 20 questions is usually enough to reveal patterns without tiring students. Shorter quizzes work well for a quick check, and longer ones give more detail on each rule.

Can I export the quiz to Moodle?

Moodle XML export is included in the Pro plan, which is $14.99 per month. PDF and DOCX export are available on Plus, and the free plan lets you study in the browser.
