Course Reviews FAQ


How does Udemy collect and use student feedback?

Like many online marketplaces, Udemy uses a 5-star rating system to collect and display student feedback on each course. The primary purpose of this feedback is to help prospective students decide if a course is a good match for their learning goals. Ratings and reviews can also help instructors identify ways to improve their content.


When and how do students leave ratings?

Students are first prompted to leave a star rating after watching 12–15 minutes of course video. They can also leave ratings directly from their “My Courses” page or their course dashboard. When they choose a rating, they have the option of providing a written review, but this is not required. Students can update their ratings or reviews at any time.

Once a student has left a rating, it passes through a filter to assess its reliability. If the filter is confident the rating represents the authentic view of a student with a genuine interest in the course, the rating will appear on your instructor dashboard and be factored into the course rating calculation.


Why are reviews and ratings important?

With a huge variety of courses to choose from, future students count on ratings and reviews to help them decide which course is right for them. By collecting and aggregating a reliably high volume of feedback from current students, Udemy’s review system gives them the information they need to help inform that decision.


How is my course rating calculated?

Udemy takes all the student ratings left on a given course in the last 90 days and aggregates them into a single course rating. That rating is displayed on the course landing page and on “course cards” across the website. Rather than using a simple mathematical average of all ratings, the course rating calculation gives more weight to reviews from its most engaged students. When assessing a student’s engagement, we consider things like course consumption, the recency of their rating, and the length of their written review.

If a given course doesn’t have more than ten ratings in the last 90 days, the course rating is calculated using the ten most recent ratings. The calculation considers only recent ratings to make the course rating a stronger predictor of how students enrolling today are likely to experience the course.


Why do you ask for a review early on in each course?

We prompt students for reviews after 12-15 minutes for three main reasons:

  1. These ratings are fundamentally accurate. On any given course, ratings left after 12–15 minutes strongly correlate to ratings left later on. For better or for worse, students tend to form opinions fairly quickly, so we choose to capture those opinions early.
  2. Collecting ratings early on lets us collect more ratings. Just like requiring written reviews, requiring lots of watch time greatly lowers the overall number of ratings left. To ensure we collect enough ratings to serve as a reliable signal for prospective students, we ask for ratings early on. This also helps courses—especially new courses—more quickly build the social proof they need to succeed.
  3. Placing the review prompt early on rewards instructors who deliver a great first impression, which is critical for student engagement. Our data and research show that if students don’t feel they’re learning what they came to learn when they first start a course, they won’t come back. So while the first review prompt does place a lot of pressure on a student’s initial experience with the course, that pressure exists independently of the prompt.

And of course, if a student isn’t ready to leave a rating, they can always click “Ask Me Later” to defer.


What will happen if a student gives my course a low rating?

Every instructor gets low ratings sometimes—you can’t please everyone, and that’s okay! That said, prospective students look at course ratings and written reviews when they’re considering enrolling in a course, and a course’s rating can affect the visibility it gets in Udemy search, recommendations, and email marketing. It’s worth it to pay attention to the overall trends in your reviews and to strive to create the best experience possible for your students.

When you do get a lower rating, consider giving the student a thoughtful response. Learn more about responding to reviews here.

If your student gives you a written review, think about this as feedback for how to improve your course. You can try to iterate your course or note for a future course.


Why doesn’t Udemy require written reviews?

Requiring written reviews dramatically lowers the number of ratings we are able to collect. When the number of ratings left on a given course is low, its course rating is less reliable, and students may lack the information they need to make an enrollment decision. Across every category and course type, courses with more reviews are more appealing to students. To ensure we collect enough ratings to be a reliable signal for prospective students, we don’t require written reviews.


Can students write anything they want in a review?

No. Please flag a review that you feel undermines the integrity of the review system so that our policy team can review it and remove it, if necessary. Read more about the types of reviews our policy team will remove here.


Does Udemy allow ratings from students who refunded the course?

Yes. Similar to a marketplace for physical goods that allows reviews from customers who return an item, Udemy allows ratings from students who have refunded the relevant course.


Can I ask other instructors for ratings and reviews on my course?

Asking for reviews is against our review policy, which you can read about here. It’s recommended you find students who are willing and interested in taking your course which will yield better quality and more relevant reviews for your course. While instructors can provide you with feedback on the quality of your videos, unless they’re familiar or interested in your topic, it is against our policy for them to leave you a rating or review on your course.


Why can’t I see the reviews from my friends and family?

Be careful to never explicitly ask for a good review from anyone, as that is against the Udemy’s rules against manipulating or influencing the review system. If your friends and family are leaving a review as a favor to you without actually watching the course, Udemy’s algorithms may flag that as a “fake review” and remove it. If you believe that a review has been removed incorrectly, you can contact the policy team. Read more information on spam filters and Udemy Review System Guidelines here.


What are the best ways to get more positive reviews on course?

Ensure that you focus on the quality of your course to drive positive reviews. Your students have expectations based on your course landing page’s learning objectives. Ensure that you are delivering a great learning experience by delivering high-quality content. Keep in mind that students are prompted to leave a review within the first 15 minutes of your course. If you receive negative reviews, spend some time responding to these reviews to learn more about how you can improve your course.


How to deal with students who lie in their reviews which Udemy won’t remove?

If a student review doesn’t violate our review policy the review will not be removed and there’s not much an instructor can do about this. You can review more about the policy here. As a best practice, many instructors respond to reviews politely requesting feedback which is helpful for future students to better understand the student perspective and the instructor interaction which may help future students disregard the specific review.


Is there a way to get notifications when a student leaves a review instead of needing to check the Course Review section everyday?

Bookmark your reviews page to easily reference your reviews. This page shows your reviews in order of recency. To access your reviews page, you must be logged in to your Udemy account on the browser where you’ve saved your reviews page bookmark.


How long does it take for your course rating to update once a review is removed?

Our systems may require up to 48 hours for the rating to update across the site. If 48 hours has passed and you still don’t see a change in your course rating, please reach out to support and they’ll take a closer look.


How long does it take for a review to update on the course landing page?

Our systems may require up to 48 hours to update across the site. While you may see the new review updated on your Instructor Dashboard, it may take longer to update on your course landing page. If you don’t see the review after 48 hours, please contact support.

As an instructor, focus on the quality and content of your course. By consistently delivering great learning experiences, your course will stand out to prospective students.
