Beyond Showing Up: Mastering Commitment & Perseverance
Learning Outcome 4 is about proving you did more than just attend. It's your chance to tell the story of your dedication over time (commitment) and how you pushed through the tough moments instead of giving up (perseverance).
Think of training for a marathon. 'Commitment' is the entire training plan: the early morning runs, the specific diet, and sticking to the schedule for months, even when you don't feel like it. 'Perseverance' is what happens at mile 20 of the actual race when you hit 'the wall', every muscle screams to stop, but you dig deep, manage your pace, and find the mental strength to push through to the finish line. Your CAS portfolio needs to show both the long-term training and how you handled hitting the wall.
- 1
Identify a Challenge: In your portfolio, pinpoint a specific, concrete obstacle or a period of waning motivation in a long-term experience.
- 2
Detail Your Actions: Describe the specific, proactive steps you took to overcome the obstacle. Don't just say 'I tried harder'; explain how you tried harder (e.g., sought advice, researched a solution, changed your strategy).
- 3
Reflect on Growth: Explain what this process of overcoming the challenge taught you about yourself, your resilience, or your problem-solving abilities. This is the 'so what?'.
- 4
Provide Corroborating Evidence: Link your reflection to evidence like a supervisor's comment praising your reliability, a series of photos showing progress over time, or journal entries detailing the problem and your solution.

Deconstructing LO4: Commitment and Perseverance as Distinct Concepts
While often discussed together, 'commitment' and 'perseverance' are not the same. Your CAS portfolio needs to show evidence of both, and your reflections should articulate the difference.
Commitment is about duration and dedication. It is longitudinal. It's about showing up for the weekly football practice for the entire season, not just the first few weeks. It's about being the person the team can rely on. It’s demonstrated by your consistent engagement over time and, ideally, by an evolution in your role from a passive participant to an active contributor.
Perseverance is about overcoming adversity. It is situational. It's about what you do when your carefully planned fundraiser is rained out, when your group members are in conflict, or when you simply cannot master a piece of music and feel like quitting. It is the active process of problem-solving and demonstrating resilience in the face of a specific, identifiable obstacle.
Commitment: Shown over time (e.g., months), involves reliability, consistency, and evolving responsibility.
Perseverance: Shown in response to a specific challenge, involves resilience, problem-solving, and emotional regulation.
A single experience can demonstrate both: Commitment is shown by participating in a debate club for a year; perseverance is shown by overcoming a fear of public speaking to compete in a tournament.
Your portfolio should contain evidence for both, even if not in the same experience.
Evidencing Your Journey: From Anecdote to Artefact
A powerful reflection is one thing, but top-tier CAS portfolios substantiate their claims with evidence. For LO4, your evidence needs to tell a story over time or capture a moment of challenge. Think like a detective: what artefacts prove your story? How can you show, not just tell, your commitment and perseverance?
For Commitment: Use a series of dated photos or videos to show a project's development. Upload a screenshot of your calendar showing recurring meetings. Most importantly, ask your supervisor to write a comment that specifically mentions your reliability and dedication over the duration of the experience.
For Perseverance: Upload evidence of your problem-solving process. This could be a photo of a whiteboard where your group brainstormed solutions, a revised budget after the first one failed, or an email chain where you sought advice from a mentor.
The Reflective Narrative: Your reflection is the glue that holds the evidence together. Use your text to point to the evidence. For example, 'As you can see in the attached supervisor review, my reliability was key...' or 'The photo below shows our first attempt, which was a failure. Here is what we did next...'
Do not treat your CAS portfolio as a last-minute task. The evidence for commitment, by its very nature, must be collected over time. Get into the habit of taking a quick photo or writing a short note after each session of a long-term project. This creates a rich timeline of evidence that makes writing your final reflections significantly easier and more authentic.
Navigating Setbacks: The Core of a Perseverance Reflection
Many students worry if they don't have a dramatic story of failure and redemption. 'Perseverance' doesn't have to mean overcoming a catastrophe. It can be found in the small, persistent struggles that are part of any meaningful endeavour. The key is to identify the challenge, articulate your response, and reflect on the outcome.
Synergy: Linking LO4 to Other Learning Outcomes
The most sophisticated CAS portfolios demonstrate how the learning outcomes are interconnected. Your commitment to a project or your perseverance through a challenge will almost certainly involve other aspects of your development. Explicitly stating these connections in your reflections shows a high level of self-awareness.
LO4 + LO1 (Strengths & Growth): 'Persevering with this difficult coding problem made me realise I have more resilience than I thought, which is a new strength for me.'
LO4 + LO2 (Challenge & Skills): 'My commitment to the MUN club over two years required me to constantly develop new skills in research and public speaking to stay challenged.'
LO4 + LO3 (Initiative & Planning): 'When our initial plan for the event failed, we had to persevere. This involved taking the initiative to create a completely new plan from scratch overnight.'
LO4 + LO5 (Collaboration): 'Our group faced a major disagreement. Persevering meant not walking away, but committing to working together to find a compromise that everyone could accept.'
LO4 + LO7 (Ethics): 'Staying committed to our environmental clean-up project, even when it was difficult and thankless, was an ethical choice to care for our local community.'
When writing a reflection focusing on LO4, end by asking yourself: 'What can I do now that I couldn't do before?' The answer might be a new skill, a new level of patience, or a new problem-solving strategy. This is the 'growth' that your CAS Coordinator is looking for and it is often the direct result of commitment and perseverance.
Worked examples
See the formulas applied — reveal one step at a time, like the exam.
A student has been volunteering at a local library for a 'Reading Buddies' programme, helping young children learn to read (Service). The experience lasts for six months. For the first two months, the child assigned to the student is disruptive and shows no interest, making the sessions feel unproductive and frustrating. Write a CAS reflection that demonstrates both commitment and perseverance (LO4).

A student is learning the guitar as a CAS experience (Creativity). After three months, they hit a plateau and are unable to play a specific chord progression cleanly, despite hours of practice. They feel demoralised and stop practising for a week. Write a reflection demonstrating perseverance (LO4).
