How do I write a performance review self-assessment?
How to write a performance review self-assessment: a simple structure, evidence over adjectives, example phrases and how to write about weaknesses.
The short answer
A good self-assessment is a short, evidence-based record of what you achieved against your goals, how you did it, where you grew, and what you want next. Start by collecting facts: your goals from the start of the period, results with numbers, feedback you received, and anything you did beyond your role. Then write a few lines for each goal or competency, leading with the result and giving one example. Be honest about one or two areas to improve, framed with what you're already doing about them. Finish with what you'd like to focus on next, including any request for development, a promotion or a pay review. Your manager will often copy your words, so write them well.
Key takeaways
- Collect evidence first: goals, results, feedback, extra work.
- Lead each section with the result, then one example.
- Name one or two growth areas with what you're doing about them.
- Close with what you want next; this is a record decision-makers may read.

Collect your evidence first
- Your goals or objectives from the start of the period.
- Results: numbers, dates, deliverables, before and after.
- Praise and feedback: emails, messages, client comments.
- Work beyond your role: training others, process fixes, cover.
- Learning: courses, new tools, new responsibilities.
- Anything that went wrong, and what you did about it.
A structure that works
- Summary: three lines on your year and your biggest contribution.
- Goals: for each one, the result, one example, and whether it was met, exceeded or missed.
- How you worked: collaboration, communication, values, with examples.
- Growth: one or two areas to improve and what you're doing.
- Next: what you want to focus on, and any support or change you're asking for.

Writing about weaknesses
Pick something real but not central to your role, and show you're on it: "I'd like to be more confident presenting to senior leaders. I've volunteered to present the quarterly update and asked for feedback after each one." Avoid self-criticism without a plan, and avoid fake weaknesses like working too hard. A thoughtful growth area makes the rest of your review more credible.
Using it for what you want next
If you want a promotion, a pay review, training or a change in role, say so in the last section, tied to your evidence: "Given the scope I've taken on, I'd like to discuss promotion to senior in the next cycle." Written requests in a review are harder to forget than ones mentioned in passing.
Questions people ask
- How long should a self-assessment be?
- Usually one to two pages, or a few sentences per goal if your organisation uses a form. Long enough to give evidence for each goal, short enough that your manager will read it all. Bullet points with a result in each are easier to read than paragraphs.
- Should I rate myself highly?
- Rate yourself honestly, with evidence. Managers notice both over- and under-rating. If you met a goal, say so; if you exceeded it, show by how much. Underrating yourself can anchor your manager's rating low, especially in organisations where ratings feed pay decisions.
- What should I write if I missed a goal?
- Say so plainly, explain briefly why (without blaming others), and describe what you did instead or what you learned. If the goal changed during the year, note when and why. A missed goal with a clear explanation reads far better than one that's ignored.
- Can I use AI to write my self-assessment?
- It can help structure your notes and tighten wording, but the evidence must come from you, and the voice should sound like you. Generic AI phrases such as "consistently demonstrated exceptional dedication" read as empty. Specific results and examples are what persuade.
- When should I start writing my self-assessment?
- Start collecting evidence on day one of the review period, and start writing a week or two before it's due. Writing the night before means relying on memory, which favours the last month and forgets earlier wins. A running note of results, updated weekly, makes the final write-up an hour's work.
