CARL stands for Context, Action, Results and Learning. It is a way to organise a reflection on an experience. Naming the four parts is not enough: explain your decisions and what the available evidence does or does not show.
The University of Edinburgh Reflection Toolkit describes CARL as adapted from an interview-answering technique. This guide uses that university explanation, not a claim that the model has been proven to guarantee professional improvement.
Core Components of the CARL Framework
The four-part structure also appears in the University of Waterloo’s reflection handout, CARL section on pages18–19. Use the prompts to organise your thinking, rather than treating every heading as a separate list of facts.
1. Context: Setting the Foundation
Give the reader enough background to understand the incident and your role. For your own notes, identify the intended task and a relevant constraint. Avoid including names or personal details that are not needed.
2. Action: Understanding Interventions
Describe your contribution and explain your choice. Distinguish what you did from what someone else did. If another option was available, explain why you did not choose it.
3. Results: Analyzing Outcomes
State what you observed after the action. Then test your interpretation: could another factor explain the result? A result that followed your action does not, by itself, prove that your action caused it.
4. Learning: Extracting Value
Explain what you now understand differently and which question remains unresolved. If you propose a next step, identify what would help you review it. A planned improvement is not an outcome that has already happened.
Practical Application
Implementation Strategies
Original hypothetical example: a student runs a vocabulary practice session for peers. The people, activity and responses below are invented for teaching; this is not a real learner’s record, a research finding or a quotation from a university guide.
- Context: I prepared a multiple-choice vocabulary quiz for our study group. I wanted to find out whether we could use the words in a new sentence, but the quiz only asked us to choose from supplied answers.
- Action: After the quiz, I asked a peer to write a sentence using one of the words without seeing the options. I chose that task because selecting an answer and producing a sentence were different things to check. I asked the peer to explain their intended meaning before suggesting a revision.
- Results: The peer selected the correct quiz option but used the word with a different meaning in the sentence. After our discussion, they revised the sentence. That shows an immediate correction in this invented incident; it does not establish long-term retention or prove that my explanation caused lasting learning.
- Learning: I had treated the quiz score as if it answered my original question about using vocabulary. Next time I would align the task with that question and revisit a word in a different context later. I would compare the responses before deciding what changed, rather than assuming that one corrected sentence proves mastery.
How to adapt the structure: replace this incident with your own evidence. Anonymise other people. If your assessment asks for academic literature, connect a source you actually read to a particular interpretation; do not use a framework citation as evidence for the invented learner’s progress.
Comparative Analysis with Other Models
Choose the framework required by your brief. The links below lead to other guides, not a ranking of which model produces deeper learning.
Gibbs’ Reflective Cycle
Use the linked Gibbs guide if that is the approach your assignment specifies. Do not rename CARL’s four parts as Gibbs’ stages.
Johns’ Model
The linked Johns guide covers a different framework. A choice between guides needs to fit the task, not an unsupported claim that one is universally more advanced.
What? So What? Now What? Model
This linked guide uses a different question structure. A short set of headings does not determine the depth of the reasoning you put beneath them.
Strengths and Limitations
Strengths
Four labels can give a reader a clear route through an account: the situation, your response, the outcome and your learning. The worked example above shows one way to use that structure, not proof that it improves every reflection.
Limitations
Edinburgh warns that a CARL response can remain descriptive. It also notes that a further action plan is not an explicit separate stage. You can add a proportionate next step where useful or required by your brief without claiming that CARL has a compulsory fifth stage.
Best Practices for Implementation
The Edinburgh Award guidance connects context and actions with outcomes and learning. For your own account, try these checks:
- Can you distinguish an observation from your interpretation of it?
- Have you explained one decision rather than only listing activities?
- What evidence would support or challenge your explanation?
- Does your learning statement say more than “I will do better”?
Conclusion
A useful CARL reflection shows what happened, why you responded as you did, what you can infer from the result and what remains to learn. Follow the assignment’s format and confidentiality rules. Do not invent a successful outcome to make the final section sound stronger.
