When to send it
Send it halfway through a course of six weeks or more, right after the session that closes the first half. That is late enough for students to have a real opinion, and early enough to change something before the course ends. Email it to everyone enrolled, or post it in the cohort's WhatsApp group with a line saying you'll share what you're changing in the next session.
Why these questions
End-of-course feedback arrives too late to help the people who gave it. A mid-point check-in lets you fix problems while the same group is still with you, and students notice when their answers lead to a change.
The first question asks how far students agree that the course is giving them what they signed up for, on a seven-point agreement scale. It is deliberately about expectations rather than enjoyment, because a course can be pleasant and still drifting away from its promise.
Pace comes next. Anyone who says it's too slow or too fast is asked which parts felt that way. A grid then rates four parts of the course, the live sessions, the materials, the practice tasks and the support between sessions, from "not working for me" to "working well". That shows where to spend your effort in the second half.
A slider asks roughly how many hours a week students can give the course outside sessions. If most say one or two and your practice tasks assume five, the tasks are the problem, not the students. The last question asks for the one change that would help most from here on.
Why there's no coupon
Students have already paid and are part-way through. A discount now doesn't improve the course in front of them, and it can make an honest check-in feel transactional. The reward that matters is seeing their answers acted on. Open the next session by sharing two or three things you heard and what you're changing, which also makes the end-of-course survey easier to ask for.
What to do with the answers
Read them within two days, before the next session. Look at the grid first: one row scoring well below the others is your priority. Pick one or two changes you can make straight away rather than promising everything, and say plainly which suggestions you can't take on and why.
At the end, send the course completion survey to the same group and compare the two sets of answers. For one-to-one clients, the coaching session review covers similar ground session by session.
