Across 4,500 classrooms, we expected adoption to correlate with teacher age or technical confidence. It did not. The strongest predictor was marking load.
Relief beats novelty
Teachers adopted the tool that solved their heaviest recurring task, and ignored everything else until that first habit was established. A teacher with 180 scripts to mark reached for the rubric generator. Feature breadth was irrelevant at that stage — it was noise.
Three patterns that held across states
- One tool first. Teachers who were introduced to a single tool stuck; those given the full suite in one session mostly disengaged.
- Peers over trainers. A colleague demonstrating a saved Sunday outperformed any formal training session.
- Twenty minutes. Onboarding longer than that reduced adoption rather than improving it.
The question a teacher is asking is not “what can this do”. It is “what will this take off my desk this week”.
How this changed the product
Onboarding was cut to a single tool chosen by the teacher, with the rest of the suite introduced only after a habit formed. Adoption at 90 days improved substantially — a result of removing material, not adding it.
