Understanding the Five Core SEL Competencies: A Classroom Guide

At a staff meeting in August, the principal announces that this year the school will "focus on SEL." A second-grade teacher nods, then quietly wonders what that means for her Tuesday morning. A high school chemistry teacher wonders whether it means something extra on top of a packed curriculum. Both have heard the term for years, but neither has a clear picture of what the skills actually are.

Social-emotional learning (SEL) becomes much easier to plan for once you can name its parts. The most widely used framework in U.S. schools, from CASEL (the Collaborative for Academic, Social, and Emotional Learning), organizes SEL into five broad, interrelated competencies.

This article explains each competency in plain classroom terms, shows what it can look like at different ages, and offers simple ways to notice and build these skills during the school day. It is a foundation for the other articles in this category, which go deeper into individual skills.

Understanding the Concept

What the five competencies are

CASEL describes SEL as the process through which young people and adults develop and apply the knowledge, skills and attitudes to manage emotions, set goals, build relationships and make responsible decisions. Its framework names five competencies:

Competency	In plain terms	What it might look like in class
Self-awareness	Understanding my own feelings, strengths, values and how they affect what I do	A student says, "I get nervous before presentations, so I practice at home."
Self-management	Managing my feelings, attention and actions to reach goals	A student breaks a big project into steps and checks them off.
Social awareness	Understanding other people's perspectives and feelings, including people from different backgrounds	A student notices a new classmate eating alone and invites them over.
Relationship skills	Building and keeping healthy relationships, communicating, cooperating and working through disagreements	Group members take turns, listen and settle a disagreement about roles.
Responsible decision-making	Making caring, constructive choices by weighing options and consequences	A student decides not to share a rumor and thinks about how it could hurt someone.

How the competencies fit together

The competencies are not separate boxes to teach one at a time. Resolving a disagreement, for example, draws on noticing your own frustration (self-awareness), staying calm enough to talk (self-management), understanding the other person's view (social awareness), communicating clearly (relationship skills) and choosing a fair solution (decision-making). CASEL's framework also places these competencies within the settings where students live and learn: classrooms, schools, families and communities. In other words, the climate of the classroom matters as much as any single lesson.

What SEL is not

• It is not therapy. Classroom SEL teaches general skills to all students. Assessing or treating mental-health concerns is the role of school counselors, psychologists, social workers and outside clinicians.
• It is not a personality test. These are skills that develop with practice, not fixed traits that students either have or don't.
• It is not separate from academics. Persisting through a hard problem, discussing a text respectfully and planning a lab all use SEL skills.

Why It Matters

Research reviews summarized by CASEL generally find that well-designed, well-implemented SEL programs are associated with better social behavior, fewer conduct problems and, in many studies, improved academic outcomes. The details vary by program and setting, and results depend heavily on how consistently the program is delivered. For teachers, a few practical reasons stand out:

• Shared language. When adults across a school use the same words for these skills, students hear consistent messages from classroom to classroom.
• Better planning. Knowing which competency a student is still building helps you choose a useful support instead of guessing.
• Stronger learning conditions. Students who can focus, cooperate and recover from setbacks are generally better able to take part in learning.

Practical Strategies

1. Build a shared vocabulary for the competencies

What: Introduce the five competencies with student-friendly names and examples.

Why: Students can't reflect on a skill they can't name.

How: For younger students, use simple phrases: "Know myself," "Manage myself," "Understand others," "Get along with others," "Make good choices." For older students, use the formal names and ask them to generate examples from their own lives, sports, music or work. Post a simple chart and refer to it in the moment: "That was self-management. You were frustrated and you took a break instead of quitting."

2. Notice and name competencies when students use them

What: Specific, private or low-key feedback that connects a behavior to a competency.

Why: Specific acknowledgment helps students see what they did well and repeat it.

How: Replace "Nice job" with "You asked Marco what he thought before deciding. That's social awareness." Keep praise genuine and avoid comparing students publicly.

3. Map competencies onto what you already teach

What: Look through an upcoming unit and mark where each competency naturally appears.

Why: This helps SEL feel woven in rather than added on.

How: A novel's characters face decisions (decision-making) and misunderstand each other (social awareness). A science lab requires roles and cooperation (relationship skills). A long-term project requires planning (self-management). Choose one competency per unit to make explicit.

4. Use brief self-reflection

What: Short, regular prompts that ask students to think about their own skills.

Why: Reflection builds self-awareness and helps students set realistic goals.

How: End a work period with one question, such as "What helped you focus today?" or "When did you get stuck, and what did you do?" Keep reflections private unless students choose to share.

5. Model the competencies yourself

What: Let students see adults use these skills.

How: "I made a mistake on the homework sheet. I'm going to fix it and let everyone know." "I hear two different ideas. Let me make sure I understand both before we decide."

Step-by-Step Implementation

1. Learn what your school already uses. Ask whether there is an adopted SEL program, schoolwide language or a counselor-led curriculum, and align with it.
2. Introduce the five competencies over a week or two, one short lesson each, with examples from students' lives.
3. Post a visual reference using the same names you'll say aloud.
4. Pick one competency to highlight each week or unit, and plan one or two moments to practice it.
5. Name competencies in the moment when students use them.
6. Add a brief reflection routine once or twice a week.
7. Share the language with families through a newsletter or conference so they can use it too.
8. Review after a few months: which competencies come up often, and which need more attention?

Sample Activity: Competency Sort

Write short scenarios on cards and have students, in pairs, decide which competency each one shows most clearly. Then discuss why several competencies might apply.

• "Jaylen felt angry when he lost the game, so he walked to the water fountain before talking."
• "Priya noticed her friend was quiet and asked if she was okay."
• "Sam decided to finish his homework before playing video games."
• "The group listened to everyone's idea and then voted."
• "Lena realized she does her best writing in the morning."

Discussion prompts:

• Which competency do you think you're strongest in right now? Which would you like to grow?
• Can you think of a character from a book or movie who showed one of these skills?
• Why might one situation use more than one competency?

Illustrative Scenarios

These are invented examples to show how the ideas might look in practice.

First grade: a "skill of the week"

Ms. Rivera introduces "Understand others" with a picture book about a child who is left out. During the week, she points out moments when children notice how a classmate feels. On Friday, students draw a picture of a time they understood someone else's feelings. One student, Amira, draws herself giving a friend a turn on the swing.

Seventh grade: competencies in group projects

Mr. Okafor assigns a research project and asks each group to choose which competency they most need to work on together. One group picks relationship skills because they argued last time. At the end of each work session, they rate how well they listened to one another and set a goal for the next day.

Eleventh grade: competencies in a career unit

In a career readiness class, Ms. Chen asks students to read job postings and highlight phrases that connect to the five competencies, such as "works well in teams" or "manages deadlines." Students then write a short reflection about which skills they want to strengthen before applying for a summer job.

Differentiation and Adaptations

• Early elementary: Use simple names, pictures, puppets and stories. Focus on one competency at a time with lots of concrete examples.
• Upper elementary: Introduce the formal names alongside student-friendly ones. Use sorting activities, role-plays and goal setting.
• Secondary: Connect competencies to real goals: sports, jobs, college, friendships. Respect privacy and avoid activities that feel childish. Let students analyze competencies in literature, history and current events.
• Students with disabilities: Some students may benefit from visual supports, extra practice, social narratives or alternative ways to respond. Coordinate with the special education team and follow the IEP.
• English learners: Pair competency names with icons and examples. Where possible, offer key terms in home languages and remember that expectations for expressing feelings and relating to others vary across cultures.

Common Challenges

• "There's no time." Start with naming competencies during existing lessons. It takes seconds and adds up.
• Students roll their eyes. Older students often respond better to real-world connections and choice than to scripted lessons. Ask them where these skills matter in their lives.
• Using the competencies to judge students. Avoid labeling a student as "bad at self-management." Describe the skill they are building instead.
• Inconsistent language across classrooms. Work with colleagues or your school's SEL team to agree on common terms.
• A student's needs go beyond classroom SEL. If you are concerned about a student's emotional well-being or safety, follow your school's procedures and involve the counselor or psychologist.

Key Takeaways

• CASEL's framework names five interrelated competencies: self-awareness, self-management, social awareness, relationship skills and responsible decision-making.
• The competencies work together, and classroom climate matters as much as individual lessons.
• Shared language, in-the-moment acknowledgment and brief reflection make SEL part of the everyday routine.
• Classroom SEL builds skills for all students; it is not mental-health treatment.

Next step: Choose one competency to highlight in your next unit and plan two moments to name it. Explore more in Social-Emotional Learning, including incorporating SEL into daily classroom instruction and teaching students to name and manage feelings.
