School mindfulness: the mixed evidence
What schools have found — both ways. One school trial found gains; a much larger one found no difference. We cite both.
School mindfulness research is mixed, and we show both sides rather than only the positive one. A randomized trial of a short daily program found gains; a much larger trial of a school-wide course found no difference.
The studies
What was tested, and what it found
Schonert-Reichl et al. 2015
Randomized controlled trial of a daily school mindfulness program.
- Who
- 4 classes of combined 4th and 5th graders (N = 99), randomly assigned.
- Found
- Students who received the program showed gains in cognitive control, stress physiology and social-emotional measures like empathy and optimism, versus a comparison group.

Enhancing cognitive and social–emotional development through a simple-to-administer mindfulness-based school program for elementary school children: A randomized controlled trial. Developmental Psychology, 51(1), 52–66. doi.org/10.1037/a0038454
Kuyken et al. 2022
Cluster randomized controlled trial (MYRIAD).
- Who
- 84 schools; 8,376 students aged 11–14.
- Found
- A school mindfulness course was no better than usual social-emotional lessons for depression risk, behavior or wellbeing after one year.

Where it stops
How each source applies — and where it stops
Schonert-Reichl et al. 2015
How it appliesSome school calming programs have helped; others haven't.A randomized trial with 4th and 5th graders found gains in attention-related skills and well-being after a short daily school program (Schonert-Reichl et al. 2015).
Kuyken et al. 2022
How it appliesLonger school wellness courses don't automatically help — brevity matters.A large UK trial found school-wide mindfulness no better than usual teaching (Kuyken et al. 2022) — one reason resets stay brief and practical.
Our next study
Whether a 30–90 second reset avoids the fade-out that full school programs have shown at scale.
How we'll measure itHow Mind Circuit uses this
Both studies tested full programs; whether a brief Micro-Reset™ works is what our own testing will show. The mixed picture is part of why resets stay short and are built around getting back to learning rather than a wellness course.
