Self-Marking
A self-assessment strategy where learners evaluate their own work against clear criteria, developing the ability to judge quality and identify areas for improvement independently.
What is self-marking?
- Share clear success criteria or a mark scheme before the task begins
- After completing the task, learners mark their own work against the criteria
- Learners identify strengths and one specific area for improvement
- The teacher reviews the self-assessment to check accuracy and provide additional feedback
How it works
Self-marking develops the metacognitive skill of evaluating one's own work. This is arguably the most important assessment skill a learner can develop, because it transfers to every context where quality matters, whether academic, professional, or personal.
The prerequisite is clear criteria. Learners cannot mark their own work if they do not know what good work looks like. Share the success criteria, a rubric, or a mark scheme before the task begins. Discuss what each criterion means and show examples of work that meets and does not meet each one.
During self-marking, learners work through each criterion in turn, checking whether their work demonstrates it. They highlight or annotate evidence where they have met a criterion and note where they have not. The final step is identifying one specific improvement they would make if they could do the task again.
Self-marking accuracy improves with practice. Initially, learners tend to over-mark (they think their work is better than it is) or under-mark (they are too self-critical). Comparing self-assessment with teacher assessment over time helps learners calibrate their judgement. The gap between self-assessment and teacher assessment is itself useful data.
The teacher still reviews the work, but the self-marking adds a layer of metacognition. The teacher can see not only what the learner produced but also how accurately they evaluated it. This reveals whether the learner understands what quality looks like.
Classroom example
A Year 7 Languages, Literacy and Communication class in a Swansea school has written short stories. The success criteria include: use of dialogue punctuation, at least one simile or metaphor, a clear story structure (beginning, middle, end), and varied sentence lengths. Learners self-mark using a green pen, ticking criteria they have met and underlining evidence. One learner gives herself a tick for dialogue punctuation but the teacher notices she has not used speech marks correctly. This gap between self-assessment and reality becomes a focused teaching point.

Self-marking develops the "Reflect" strand of thinking skills by building learners' capacity to evaluate their own work honestly and accurately. It supports the Four Purposes by developing "ambitious, capable learners" who can independently judge quality and take ownership of their improvement.
Rainbow Curriculum's Thinking Tools lens helps you plan where self-assessment is embedded across your curriculum, building a culture where learners are active participants in evaluating and improving their own work.
Tips
- Start with simple, objective criteria (e.g., "Did I include three examples?") before moving to qualitative judgements.
- Use a different coloured pen for self-marking so teacher feedback is visually distinct.
- A common pitfall: self-marking without any teacher follow-up. If learners never compare their assessment with the teacher's, they cannot improve their accuracy.
- Combine with peer marking so learners see how others evaluate similar work.
- Track self-marking accuracy over time. Celebrate improving accuracy as a skill in itself.
