This randomized trial tests the idea that nurturing coping flexibility through a social and emotional learning intervention, Passport, will improve children’s mental health. We find that this is not the case and conclude that it is not sufficiently differentiated from existing social and emotional learning provision to make a difference. On the basis of our findings, Passport cannot be recommended as an effective means to reduce mental health problems.
For starters, teachers are not counselors and should not be put in a position where they’re required to be a frontline first-responder to kids’ mental health challenges. That SEL attempts don’t work shouldn’t be surprising.
