Learning outcomes
Measuring What Matters: Learning
On average, students' assessment scores rose by 35 percentage points between the pre-assessment and the post-assessment.
+35percentage points
Points, not percent. A 35-point gain takes a student from, for example, 40% to 75%. It is not a score 35% higher than the one before. Reported as of October 2026.
Step 1
Diagnostic
A short pre-assessment before a course or workshop shows where each student starts.
Step 2
Practice
Lessons with checkpoints, unit quizzes and worked feedback, at the student's own pace.
Step 3
Post-assessment
A matched assessment at the end. The gain is the change in the same students' scores.

Where the material actually sits
Lessons per course, in catalogue order. The ladder gets heavier as it climbs, which is what it should do — and it shows plainly where the thin parts still are.

Methodology
How every number on this page is produced
Two kinds of figure, kept apart on purpose. Reported figures are collected by the team and dated. Counted figures are read from the database when the page loads.
- Learners reachedReported
- Students who have taken part in a StatSprout workshop or worked through StatSprout material. Counted by the team, not by sign-ups. Source: In-person workshops and the StatSprout platform.As of October 2026
- Countries reachedReported
- Countries where StatSprout learners have taken part. Recorded at country level only; no finer location is collected or shown.As of October 2026
- Assessment improvementReported
- Average change in assessment score between a pre-assessment and a post-assessment taken by the same students, measured in percentage points. A gain of 35 points means, for example, 40% to 75% — not a score 35% higher than before.As of October 2026
- Courses, lessons, problemsCounted live
- Read from the curriculum database on each page load. Only published content whose course, unit and lesson are all published is counted. Headline figures are rounded down to two significant digits.Last updated Oct 17, 2026, 2:18 AM UTC
What holds regardless
Three things that do not depend on scale
Free, with no tier above it
Every course, every lesson, every assessment. There is no paid plan and no plan to add one.
Private by default
A student's progress is a record for them. It is never published, ranked, or shown to other learners.
Open without an account
The first course runs in full with no sign-up, so nobody has to hand over an email to find out whether this is any good.
Next
Help the next hundred learners
Use it, or help run it. Every student who works through a course, and every workshop a volunteer runs, is how these numbers grow.
