How to choose a live quiz platform for your class

The short version: what really matters

Almost every live quiz platform looks good in a demo. The differences show up in a real lesson, with 28 students, a mix of phones and a busy Wi-Fi network. So it pays to judge a platform on a few simple criteria you can check yourself in a free account, before you pay for anything.

• Joining: how fast students get into the game and whether they need an account or an app.
• Formats: which question types you get and whether you can mix quizzes with polls or open questions.
• Free plan: how many participants, how many quizzes and how long results are kept.
• Student data: what is collected about students, where it is stored and how you delete it.
• Devices: what you need in the room and what happens when a phone drops off the network.
• Import and support: whether you can bring your existing material and who answers when something breaks.

1. How students join

At the start of a lesson, every minute counts. Ideally, students open the browser on their phone, type a game PIN or scan a QR code on the projector, and they're in. If a platform needs an account or an installed app, you lose time, and you run into trouble with students who aren't allowed to create accounts.

Also ask what happens when someone disconnects. A phone that loses the network shouldn't throw a student out of the game or wipe their score.

2. Question types and formats

Single choice and true / false cover a lot of lessons, but not all of them. For proper revision it helps to have typed answers, ordering, matching or a slider for numbers. Check which types are included in the plan you would actually use, not just in the most expensive one.

Think about the moments when you don't want a right answer, too: an opinion poll, an open question or a word cloud at the end of the lesson. If those formats run in the same session as the quiz, students don't have to join again with a different code.

For assessment, look for a test mode: students work on their own, with no leaderboard on the screen, and you get a grade for each of them.

3. The free plan and the real price

A free plan is only useful if it fits your class. Read the actual limits, not just the word "free":

• how many participants can join one session (a class is usually 25 to 30 students);
• how many quizzes you can keep in your account;
• how long session results are kept and whether you can export them;
• whether you have to enter a card to sign up;
• what you pay after any introductory offer, and how you cancel.

4. Student data and GDPR

For a school, privacy matters as much as features. Read the privacy policy and look for clear answers to a few questions: what students are asked for, where the data is stored, how long it is kept, which providers are involved and how an account and its data are deleted.

A practical rule that works on any platform: if students type only a first name or a nickname when they join, you collect less personal data. For graded tests, agree with your school on how students are identified.

5. The devices you need

You usually need a laptop connected to a projector or an interactive board, plus one device per student: a phone, a tablet or a laptop from the computer lab. Check that the platform runs straight in the browser, on older phones as well, and that the projector screen is separate from your control panel, so students don't see the correct answers early.

6. Importing what you already have

If your questions already live in a spreadsheet, or you have used another quiz platform, an import can save you hours. Ask which formats it accepts (for example .xlsx or .csv), whether you see a summary before anything is added, and what doesn't come along, such as images.

7. Interface language and support

An interface in your students' language helps younger classes and colleagues who don't use technology every day. Also check how you get help: a contact form, an email address, a response time.

How to test a platform before the lesson

1. Make a 5-question quiz with at least two different question types.
2. Launch the session on your laptop and join from two different phones, as students.
3. Switch Wi-Fi off on one phone for a few seconds and see whether it gets back into the game.
4. At the end, open the report and check what data you got about each participant.
5. Look in the privacy policy for where the data is stored and how you delete it.
