When to send it
Ask in the last five minutes of the workshop rather than afterwards. Put the QR code on your closing slide or on a printed card on each table, and give people a moment to scan it before they pack up. Feedback gathered in the room tends to be fuller than a link sent the next day, when attention has moved on. For anyone who left early or joined online, post the same link in the workshop's WhatsApp group that evening.
Why these questions
The first page has a star rating for the whole workshop and a grid that scores four parts separately: the content, the pace, the hands-on exercises and the venue or call setup. A single overall score hides a lot. The grid tells you whether a middling rating came from the material or from a cramped room with patchy wifi.
The second page asks whether the level felt right. Mixed groups are the hardest part of running workshops, and this shows how many people felt left behind or held back. Anyone who picks "too basic" or "too advanced" is asked which parts felt that way, so you know which section to adjust.
The last page has three open questions: the most useful thing they learned or tried, one change for next time, and which topic would bring them to another workshop. Answers to that last one become a ready-made list of future workshops, ranked by how often each topic is mentioned.
The coupon
A shared 15% code for the next workshop rewards people for staying the extra minute and turns the end of one workshop into a booking for the next. Because the whole group gets the same code, you can mention it out loud as you put the QR code up. People see it once they finish, however they rated the day.
What to do with the answers
Compare the grid row by row across several workshops rather than reading one in isolation. If the hands-on exercises score lower each time, cut a section of talk and give the exercises more room. Read the level answers next to your sign-up details: if "too basic" comes mostly from experienced people, consider running separate beginner and advanced versions.
For one-off talks and conferences, the event attendee feedback template covers speakers and venue in more detail. For programmes that run over several weeks, the course completion survey is a better fit.
