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. 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). A 10-lesson course.
- 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.

What it studied
How each source applies, and what it studied
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 appliesSchool-wide courses don't automatically help at scale.A large UK trial found school-wide mindfulness no better than usual teaching (Kuyken et al. 2022) — one reason resets stay brief and practical.
What our research looks at
How consistently a 30–90 second reset runs across different classrooms and grades.
How we'll measure itHow Mind Circuit uses this
Both studies tested full programs. The mixed picture is part of why resets stay short and are built around getting back to learning rather than a wellness course.
