Social-emotional learning, usually shortened to SEL, is the part of school where children learn to understand their feelings, get along with others and make good choices. It is not a separate subject so much as a set of skills that shows up all day long: in the line at the door, in a disagreement over a glue stick, in the moment before a spelling test.

This guide explains the framework most US schools use, what it looks like with five- to eleven-year-olds, and why it is worth a few minutes of every school day.

A working definition

The Collaborative for Academic, Social, and Emotional Learning (CASEL), a nonprofit founded in 1994, is the organization behind the most widely used SEL framework in American schools. In CASEL's description, SEL is the process through which children and adults build and apply the knowledge, skills and attitudes to develop healthy identities, manage emotions, reach goals, show empathy, build supportive relationships and make caring decisions.

Two parts of that definition matter most for an elementary teacher. First, SEL is for children and adults: the way a teacher handles their own frustration is part of the lesson. Second, these are skills, not fixed personality traits. A child who melts down when they lose a game is not "a sore loser"; they are a learner who has not yet practised what to do with disappointment.

The five CASEL competencies

CASEL groups SEL into five broad, connected areas. The framework is often drawn as a wheel, with the student at the centre, surrounded by the classroom, school, family and community.

CompetencyIn plain wordsWhat it looks like in K-5Quick activity
Self-awarenessKnowing my feelings, strengths and valuesNaming a feeling with more than "good" or "bad"; saying "I'm good at drawing, still learning subtraction"Feelings colour check-in
Self-managementHandling my feelings and actionsTaking three breaths before reacting; waiting a turn; sticking with a hard taskOne-minute breathing
Social awarenessUnderstanding other people's point of viewNoticing a classmate is left out; respecting different families and traditionsSocial skills scenarios
Relationship skillsGetting along and working togetherTaking turns in a group, listening, apologising, asking for helpSharing questions
Responsible decision-makingMaking caring, safe choicesThinking "what could happen next?" before acting; fixing a mistakeGoal setting with obstacles

In practice the competencies overlap. A morning meeting greeting builds relationship skills, but a shy child who manages to say "good morning" while making eye contact is also practising self-management. That overlap is a feature: one well-chosen activity usually touches several competencies at once.

Three groups of skills you can teach on command

When this site first started, it sorted classroom SEL into three plain-language groups that map neatly onto CASEL's five areas. We still find them the easiest way to plan:

  • Owning emotions and behaviour (self-awareness and self-management): emotion management, mindfulness, daily affirmations and inspirational quotes, and energy management.
  • Empathy and working with others (social awareness and relationship skills): social skills scenarios, sharing and reflection questions, and small-group work.
  • Setting goals and overcoming obstacles (self-management and decision-making): goal setting and time management, growth mindset and on-task focus music.

What the research says

The best-known evidence comes from a 2011 meta-analysis led by Joseph Durlak and colleagues, which pooled 213 school-based SEL programmes involving around 270,000 students from kindergarten to high school. Compared with control groups, students in SEL programmes showed better social-emotional skills, attitudes and behaviour, and an average gain of about 11 percentile points in academic achievement. A 2017 follow-up review found that some benefits were still visible months and even years later.

Two cautions keep that evidence honest. The strongest results came from programmes that were well implemented: sequenced, active, focused and explicit. And SEL is not a cure-all; it works best alongside good teaching, safe school climates and support from counsellors when a child needs more than a classroom routine can give.

SEL happens in context, many times a day

The single most useful idea we can offer is this: social-emotional learning happens in context, many times a day, not once a week. A 40-minute SEL lesson on Friday is valuable, but the skill is built in the 30-second moments: the calm-down breath after recess, the sharing question while the class waits for lunch, the reflection before the bell. Our guide to SEL in five minutes shows how to plan for those moments.

Start small: pick one competency for the month, one routine to practise it (a greeting, a check-in, a breathing break) and one phrase you will use every time. Consistency teaches more than variety.

Where to go next

If you are new to SEL, try morning meeting first; it touches all five competencies in fifteen minutes. If you lead a team or a school, read bringing SEL to the whole school.
