Across 26,632 courses on Ruzuku, scheduled cohorts average 53.4% completion — 4.2x the 12.6% MOOC industry median. The First-Week Multiplier is the strongest signal: students active in week one finish at 78.3% vs 17.2% for those who don't. The Assessment Effect adds a 16.7-point lift. The Discussion Dividend adds 13.6 points. And The Accountability Sweet Spot is 11-25 students per cohort.
Over 14 years of building Ruzuku, we've accumulated something no affiliate site or industry survey can replicate: production data from 27,156 courses, 1,316,272 student enrollments, and 14.2 million individual lesson completions. The completion figures on this page are measured across the 26,632 courses and 1,253,716 enrollments that carry at least one lesson and one student, with enrollments counted where the membership is active. This page is the canonical reference for that data — the numbers I draw on when advising course creators, and the source behind every platform statistic cited on this site.
Two numbers to keep straight. Ruzuku has published more than 32,000 courses across its catalogue; this dataset covers the 27,156 of them that have at least one lesson and at least one enrolled student, because a course with neither cannot have a completion rate. Where this page and the rest of the site quote different totals, that is the difference.
Platform Scale
Completion Rates by Course Format
The single most important finding from our data: course format matters more than content quality for predicting whether students finish. Scheduled cohort courses outperform self-paced open-access courses by 11.5 percentage points — a consistent gap across niches and price points.
For context, the median MOOC completion rate is 12.6% according to Class Central. Even our lowest-performing format (self-paced open access) is 3.3x higher than marketplace platforms. The difference is the instructor relationship and community structure that comes with hosted platforms versus anonymous marketplaces. For a deeper dive, see Cohort vs Self-Paced: What the Data Shows.
The Assessment Effect
Courses that include quizzes, polls, or assignments see a 16.7 percentage point lift in completion — the largest single-feature impact in our data.
Of the 26,632 courses in this dataset, 5,598 use at least one assessment type and 21,034 use none. Students have submitted 333,592 quiz, poll, and assignment responses across the platform. Skool, for comparison, offers no assessment features on any plan.
The Discussion Dividend
Community discussion is the most researched predictor of online course success. Our platform data confirms the academic literature.
Courses with lesson-level discussions average 50.9% completion, measured per enrollment, against 37.3% for courses without them. Discussion is the norm rather than the exception: 17,190 of the 26,632 courses in this dataset have lesson-level discussions, and students have posted 5.1 million comments. The pattern does not hold in every field. In two of the twelve niches we break out — therapy and counseling, and health and medical — courses without lesson discussions complete at the higher rate. Each niche page carries its own numbers.
The Accountability Sweet Spot — Cohort Size
Not all cohorts perform equally. When we break down completion rates by group size for scheduled courses, a clear pattern emerges:
| Cohort Size | Courses | Avg Completion |
|---|---|---|
| 1-10 students | 4,052 | 51.5% |
| 11-25 students | 2,716 | 65.2% |
| 26-50 students | 1,400 | 62.0% |
| 51-100 students | 712 | 56.8% |
| 100+ students | 679 | 51.3% |
The 11-25 student range is the sweet spot — large enough for rich peer dynamics, small enough that each student feels accountable. Both very small groups (1-10) and very large groups (100+) see lower completion rates, for different reasons: small groups may lack the social energy to sustain engagement, while large groups dilute individual accountability.
The First-Week Multiplier
The strongest predictor of completion in our data isn't course format, assessments, or group size. It's whether the student does anything in the first seven days.
That's a 4.6x difference. Students who complete at least one lesson in week one go on to finish at a 78.3% rate. Students who do nothing in week one finish at 17.2%. The comparison covers 352,908 active and 568,951 inactive students, limited to enrollments from the last five years. If you do nothing else with your course design, focus on getting students to take action in the first week. A welcome assignment, an introductory discussion prompt, a quick win exercise — anything that creates momentum.
Pricing Benchmarks
Half of one-time course prices fall between $49 and $357, and the upper tail runs a long way past that: certification courses, coaching cohorts, and professional development programs command $500-$5,000+. Across 408 coaching programs with a one-time price, the median is $1,898, with the middle 50% between $399 and $4,999 — about 13 times the platform-wide median, driven by transformation specificity and instructor involvement, not production quality. An earlier version of this page reported $531 as the coaching median. That figure was a payment-plan instalment, not a price. One price per course, instalment plans excluded.
Other pricing data: 37.6% of listed price options are free. For detailed pricing guidance, see the Complete Course Pricing Guide.
Time to Completion
The contrast is striking. Cohort students work through material over roughly a month — a pace that allows for reflection, practice, and peer discussion. Self-paced students who do finish tend to binge the content in under a week. Both are "completion," but they represent very different learning experiences. The median creator on Ruzuku has published 8 courses, suggesting that the multi-course model — not one-shot — is how sustainable course businesses work.
Methodology and Limitations
Comparative Benchmarks
How does Ruzuku compare to other platforms? Published completion data is scarce — most platforms don't share their numbers. Here's what's available alongside our data:
| Platform / Source | Completion Rate | Notes |
|---|---|---|
| Ruzuku (cohort) | 53.4% | Scheduled courses, 337,700 enrollments |
| Ruzuku (self-paced, open access) | 41.9% | Open-access courses, 702,497 enrollments |
| Udemy | ~10-15% | Estimated from public reports |
| MOOC median | 12.6% | Class Central, 2023 |
| Coursera | ~6-7% | Widely reported for free courses |
External benchmarks are from public reports and may use different completion definitions. Ruzuku data is from the Course Success Index production analytics.

Frequently Asked Questions
What is the Ruzuku Course Success Index?
First-party data from 27,156 courses hosted on Ruzuku over 14 years — completion rates, engagement benchmarks, pricing data, and cohort sizing. Unlike industry surveys, this data comes directly from production platform analytics.
What is the average online course completion rate?
Format changes the answer enough that a single blended number would mislead. On Ruzuku, cohort (scheduled) courses average 53.4% completion, on-demand drip courses 42.9%, and self-paced open-access courses 41.9%, measured across 1,253,716 active enrollments. Courses with assessments reach 59.1%. The industry benchmark for self-paced MOOCs is a 12.6% median (Class Central, 2023).
What is the ideal cohort size for an online course?
Based on our data, 11-25 students is the sweet spot at 65.2% completion. Both smaller (1-10, at 51.5%) and larger (100+, at 51.3%) groups see lower rates.
How much should I charge for an online course?
The median one-time course price on Ruzuku is $150, with the middle 50% between $49 and $357 across 11,691 courses. Coaching programs run much higher: a median of $1,898, with the middle 50% between $399 and $4,999 across 408 programs. Price is driven by transformation specificity, not course length or production quality.
How often is the Course Success Index updated?
Data is drawn from the production database and refreshed periodically. Current data reflects 14 years of history through August 2026.
