Many studies since the 1990s of the effectiveness of prioritizing what educators call Social-Emotional Learning alongside academic learning report notable improvements in grades and attendance.
Other reported include improvements in healthy and positive interpersonal relationships between students and between students and teachers, and overall higher emotional literacy and better classroom climate.
Students also tended to show improvement in clear thinking, effective decision-making and self-management along with significant decreases in problem behavior. Some studies found that physical health improved along with psychological health.
A pre-Covid 2004 meta-analysis that looked at the results of 207 separate research studies, reported that SEL-supported students performed significantly better in school (11 percentile points or 20% higher) on standardised tests compared to non-participating students. (See Zins, J. E., Weissberg, R. P., Wang, M. C., & Walberg. H. J. (Eds.), (2004). Building academic success on social and emotional learning: What does the research say? New York: Teachers College Press.).
A separate landmark meta-analysis of 213 school-based SEL programs involving 270,034 students, from kindergarten through high school, demonstrated significantly improved social and emotional skills, attitudes, behavior, and academic performance.
A 2023 to 2025 study after a sudden mass expansion of SEL into U.S. schools to deal with COVID-related student emotional states and damaged mental health, found only a 4.2% improvement in academic scores – not surprisingly given the more troubled mental states of students and the rapid expansion of SEL in late 2021 and 2022.
A pioneering cost/benefits analysis undertaken by noted education economists at Columbia University and published in the American Journal of Public Health found an average return on investment of $11 for every dollar spent on SEL programs. Known benefits included: reductions in outcome costs of child aggression, substance abuse, delinquency, and violence. The study also reported lower levels of depression and anxiety; and improved grades, attendance, and performance in core academic subjects.
A Washington State Institute for Public Policy study of one program, PATHS, reported that it yielded a benefit-cost ratio of $15.66 for each dollar invested, and provided long-term results.
An important study released in July 2015 that examined nearly 20 years of data from the Fast Track Research Project reported that learning social competence in kindergarten consistently predicted positive outcomes in education, employment, criminal justice, substance use, and mental health into adulthood.
Kindergarteners with higher social competence scores were measurably more likely to attain a college degree, more likely to earn a high school diploma, and more likely to have a full-time job at age 25 than non-participants. The study was controlled for race, class, and income factors, and improvement was across the board.
One program (Second Step) reported that, after only one year, sixth-graders in 36 tests schools were 42% less likely to say they were involved in physical aggression compared to sixth-graders in schools that did not implement the program.
Other positive reports come from individual SEL programs that have commissioned independent research studies. In one study by a team from University of British Columbia of the MindUP™ program, 96% of 3 year olds increased inhibitory response (less emotional outbursts) and 73% of third graders showed improved planning and organizational skills. Another program (Responsive Classroom) reported that, after a short time, students’ scores on cognitive skills tests improved by 20%.
Prevention and intervention programs targeting school violence, bullying, conflict resolution and school safety are fairly common within the pre-college education community.
However, comprehensive pre-school through 12th grade SEL programming integrated throughout all school contexts has a ways to go – this despite a soaring rate of partial adoption of programs in U.S. schools – initially to help schools deal with the mental health crisis brought on by COVID restrictions and growing since
Many schools have found less comprehensive ways to have children experience some form of this learning. And many after-school programs across the country have added similar programs and report positive results.
At their best, the organizations providing programming train administrators to be EQ and SEL champions. They begin by facilitating buy-in from teachers, other staffers and students. They can also train teachers to implement the programs with fidelity, provide roll-out support, and ensure all adults in the building are educated in basic EQ and SEL concepts.
Students are supported with a variety of multi-media materials while the schools themselves receive ways of measuring implementation success and student outcomes over time for learning purposes.
Finally, strong programs take a “whole-school” approach that integrates the learning and practices throughout school contexts other than classrooms (the play yard, the cafeteria, the hallways, after-school programs, community service, and so on). They also offer students direct skills instruction (often in periods devoted to EQ classes), opportunities to practice those skills throughout the day, and integration with academic lessons.
Parents in these schools are encouraged to be engaged, both in school and at home, and can be referred to home-based instructional materials.
Studies show that the “whole school” approach is essential for sustained impact. Programs deployed on a fragmented basis for crisis management or one-time assemblies rarely have a lasting effect.
The gold standard way of measuring a program’s effectiveness is a randomized control trial – often referred to as an “evidence-based” test – meaning either a similar partner school or a grade level or sector of the testing school does not get to experience these programs and results are compared over a set period of time.
A growing number of programs have undergone a rigorous study of this kind.
The next best is a “research-based” program, meaning its entire design was guided by well-researched principles of social and emotional development.
A few years ago and before COVID, as SEL was gradually increasing its presence in school, we interviewed Nadine Heimannthen, executive director of True Connection a small, largely self-funded organization. Their volunteers, including Heimann, trained teachers and students pro bono in research-based EQ practices, positively affecting their academic performances. Her experience stands up as similar to that of many educators.
"Almost all the kids we deal with feel isolated and emotionally upset when you scratch the surface,” she told us. "They don’t know how to control their emotions; don’t have the tools for self-love or forgiveness of others. They don’t know how to empathize. Their learning and creativity suffer a lot and they mostly feel helpless.
Once they learn and practice these really simple tools, everything turns around for them. They know how to deal with their feelings, they understand and can practice self-love, and they become empathetic and understanding of others.
They learn how to collaborate with others and become intuitive problem solvers. It’s so evident they need these social and emotional practices in school every day. That’s what sets them up for true success. You need these skills to be successful in anything you do.
Most importantly, it sets them up to lead meaningful, purposeful lives, and they deserve that. The future of humanity and the planet depend on it."
Below are brief summaries of independent research findings undertaken for several different SEL programs seeking to measure the effectiveness of their own approaches.
One RULER study focused on the academic performance and social and emotional competence of 273 5th and 6th grade students in 15 classrooms in three schools.
Academic performance was assessed by report card grades. Social and emotional competence was assessed with teacher reports of student behavior.
Students in classrooms integrating RULER had higher year-end grades and higher teacher ratings of social and emotional competence (e.g., leadership, social skills, and study skills) compared to students in the comparison group.
From 2008 to 2011, researchers at the University of Virginia’s Curry School of Education conducted a three-year randomized control trial of this classroom SEL training funded by the U.S. Department of Education.
Teachers were recruited from public preschool classrooms in Florida and Tennessee that served children with, at risk for, and without disabilities. Data were collected on a total of 484 children in these classrooms (252 intervention; 232 control), including two to three target children per classroom who were identified as having behavioral challenges (54 intervention; 43 control).
Following the intervention, non-target children whose teachers were in the intervention group were rated significantly higher on social skills than non-target children whose teachers were in the control group.
Target children within classrooms in the experimental group had statistically significant and noteworthy reductions in problem behavior as rated by teachers in comparison to target children whose teachers were in the control group.
It was the subject of a 2010 randomized control trial over a one-year period with 7,300 students and 321 teachers in 61 schools across six school districts, from kindergarten to second grade.
Significant improvements in social-emotional competence and behavior were made by children who started the school year with skill deficits in these areas.
Another study of 1,253 second- through fourth-grade children found those who participated in the Second Step program showed greater improvement in teacher ratings of their social competence, were less aggressive, and were more likely to choose positive goals than the control group.
36 middle schools in the Chicago and Wichita areas participated in an evaluation of the Second Step Middle School program. After one year, sixth-graders in schools that implemented the program were 42% less likely to say they were involved in physical aggression compared to sixth-graders in schools that did not implement the program.
What many teachers feel after SEL is in their schools:
"It feels like home, it feels like family, you are forced to grow, to push to challenge yourself, to let go of the things that you have inside that don’t work well. And I’d become a better person as a human being for being here, not just a better teacher."
Marc Brackett, founding director of Yale’s Center for Emotional Intelligence, and co-founder Susan Rivers , explain EQ.
An academic definition of emotional intelligence:
"The process of integrating thinking, feeling, and behaving in order to become aware of the self and of others, make responsible decisions, and manage one’s own behaviors and those of others."
