A good Evaluation is short and pointed. Every extra question costs you a little response quality — people rush, skip, or drop off — so the ones you keep should each earn their place. Here are a few tips for writing questions participants will actually answer, and that tell you something you can use.
Ask only what you'll act on
Before you add a question, ask what you'd do differently depending on the answer. If no answer would change anything, cut it. An Evaluation isn't the place to collect data just in case — it's the place to learn the few things that shape what happens next.
Match the question type to what you want
Use Rating when you want to measure something and compare it — confidence, satisfaction, how clear a session was.
Use Open-ended when you want the "why" behind the numbers, or ideas you haven't thought of.
A common pattern is one Rating followed by one Open-ended: the score shows the direction, the written answer explains it.
Reach for Multiple choice when the useful answers are a known, short list, and NPS only when you specifically want the recommendation score.
Keep each question about one thing
"Was the session clear and useful?" hides two questions — someone can find it clear but not useful, and won't know which to answer. Split it. One idea per question makes answers easier to give and far easier to read later.
Use anonymity to your advantage
Because Evaluation answers are anonymous, you can ask the honest questions that matter — about a manager, a format, or whether something's really working. Word them so people feel safe being candid.
Ask while it's fresh
Send the Evaluation close to the experience you're asking about. The longer you wait, the more people answer from a vague memory rather than a clear one.
When you're ready to build, see creating an evaluation.
