A written performance review is a record. Other people may read it later. A calibration group, a promotion committee, or a future manager can form an impression from a document that omits concrete work. When your achievements are missing or understated, you can correct the record while the review is still open to changes. The right step depends on your company's process, so check what is allowed before you ask.
The goal is to make sure the facts in the document are complete and accurate. Missing work is different from a low rating. Missing work may be added if the process allows it. A low rating may need a separate conversation about how the manager evaluated the work. Handle the missing facts first.
Separate missing facts from rating disagreements
When a review leaves out your achievements, separate two issues. One is an omission. A project you led is not mentioned, a result is missing, or a task you performed is assigned to someone else. The other is a disagreement about the rating. The review lists the work but rates it lower than you expected. Correcting an omission can be simpler because you are adding a fact. Correcting a rating asks the manager to change an evaluation, which may be a different conversation.
A hypothetical example. You built an internal tool that reduced manual entry errors. The review mentions your support tickets but not the tool. That is an omission. If the review mentions the tool but says it had low impact, that is a rating disagreement. Handle them separately. Start with the missing facts.
Gather the missing items with evidence
Before you ask for a correction, build a short list. For each missing achievement, write a few lines. Include what you did, the outcome, when it happened relative to the review period, any document that shows the work, and who saw it. A relative date helps place the work in the period the review covers. Keep the list to one page. A long list can read as a complaint. A short factual list is easier for a manager to act on.
Use documents you already have. A project doc, an email thread, a dashboard, or a note from a colleague can show the work and its result. If someone else saw the work, include their name and what they saw. A witness can help when the person reading the review does not know your daily activity.
Stick to facts. Do not include interpretations like "this shows I am underrated." Write "Led the data cleanup that cut duplicate records" instead of "My work was ignored."
Check what is missing. An omission can be a full project, a single result, a skill you used, or a problem you prevented. Problems prevented are often invisible because there is no failure to point to. If you caught an error before it reached a client, the silence looks like nothing happened. Note it as a missing item and what it prevented.
Ask for a short correction conversation
Once your list is ready, ask your manager for a brief conversation. Say that you reviewed the written review and noticed some concrete work is missing. Ask whether you can walk through the list and see if the review can be updated. Keep the request short. Do not write a long email explaining every item in advance. If your manager asks for more detail before the meeting, send the one-page list, not a long narrative.
Before the meeting, check how your company's review process works. Ask whether a manager can add a comment, attach a note, or update a draft. If the process finalizes the review with no edits, ask if a written addendum or email summary can be placed in your file. Do not assume the process. Ask.
During the conversation, present one missing item at a time. State the work, the result, and who saw it. Then ask a specific question. "Can this be added to the review?" or "Is there a way to attach this note?" A specific question is easier to answer than "Why was this left out?" Save the why for after you know what can be changed.
Why it may have been left out
There are several possible reasons a manager leaves out real work. They may not have seen it. They may have drafted the review from recent notes, so older work faded. They may not have connected a result to you because someone else presented it. They may have focused on the most visible tasks and missed the work that prevented problems.
These are possibilities to check, not conclusions. Ask your manager in the correction conversation. For example, say "I noticed the pricing analysis is missing. Was that something you were aware of?" The answer can help you learn what happened. If the manager did not know, you can show the evidence. If the manager knew but left it out, ask what was missing from their view. That leads to the rating conversation, which may be separate.
Do not assume bad faith first. A manager who missed your work may correct the record once you show the facts. A manager who dismisses the evidence after seeing it is different. Keep the first conversation factual and give them room to fix an oversight.
Keep the correction short and factual
During the conversation, stay on the missing items. Do not turn it into a general complaint about feeling undervalued. The review is the record. Your list gives you a concrete way to talk about it.
If the manager agrees to add something, repeat back what they agreed to. "You will add the data cleanup and the client onboarding result." Ask who will make the change and how you will know it is done. That keeps the follow-up simple. If the manager says the review cannot be changed, ask what written step is allowed. If no step is allowed, note that the correction conversation still creates a shared understanding. The permanent record may remain incomplete.
After the meeting, send a short note summarizing what was agreed. Write something like "We talked about adding the data cleanup and the client onboarding result to my review. You said you would update the document." Keep the note factual and short. Do not add emotional language. The note is a record of the conversation, which can help later if the correction is not made.
If the missing item is part of a larger need for specific credit, how to ask for recognition at work covers how to make that ask in other settings. Use the same factual approach.
Prevent the next review from having gaps
A corrected review fixes the current record. The next review can have the same gaps unless you change your routine. Keep a running record of what you do, with results and dates relative to the review period. Update it monthly or after each completed project. Use that record when you write your self-review and when you meet with your manager. When you finish a piece of work, write a two-line note to yourself with the result and who saw it. That note becomes the evidence you need later.
Share wins during the cycle, not only at review time. A short note to your manager after a result, or a mention in a team meeting, makes the work easier to recall. How to get visibility at work explains how to be seen for work you are already doing. Use that approach throughout the year.
If you want specific recognition in a document or meeting, ask for it directly. A general request for appreciation can be answered with a nod and no action. Name the form: a line in the review, credit on a project page, or a mention to the person deciding your next move. Ask early in the cycle to reduce corrections at review time.
The position you're deciding from
When the review correction is done, or when it cannot be changed, step back and decide what to do with the information. You can count on a few things. You can count on the record you built: the missing items, the evidence, and who saw the work. You can count on having made a specific request, so the answer you received tells you something even if it was no.
Check whether the corrected record would actually change your position. If the review feeds a promotion case or a future manager, missing facts matter. If the review is filed and never read again, the correction may matter less. Check who actually controls the decisions the review affects. Your manager may be the only reader, or a committee may read it. Ask how the review is used in your company before drawing conclusions.
If the manager added the missing items, you can stay with a cleaner record and keep sharing wins during the next cycle. If the manager did not add them and gave a clear reason, decide whether that reason affects your trust in the rest of the review. If the manager repeatedly leaves out concrete work after you provide evidence, that pattern is information. It may mean your manager does not see your work, does not value it, or cannot influence the record. You can ask again with a different audience, such as a skip-level manager who saw the work, if that is allowed in your company.
The correction conversation may not lead to credit. It still gives you a clearer read on the place you are in. Use that specific read to decide whether to stay, ask again, or leave.

FAQ
What should I do first if my review left out a concrete achievement?
Separate the omission from a rating disagreement. Build a short factual list with what you did, the outcome, when it happened relative to the review period, any document, and who saw it. Keep the list to one page before asking for a conversation.
How do I ask my manager to correct the review without sounding defensive?
Ask for a brief conversation and say you noticed concrete work is missing. Present one item at a time, state the work, the result, and who saw it, then ask a specific question like whether it can be added. Keep the tone factual and avoid general complaints about feeling undervalued.
What if my manager says the review cannot be changed?
Ask what written step is allowed, such as a comment, note, or addendum if the process permits. If no step is allowed, the correction conversation still creates shared understanding. The permanent record may remain incomplete. Send a short note summarizing what was discussed.
How do I stop this from happening next time?
Keep a running record of wins with results and relative dates, and share them during the review cycle. Ask for specific recognition when the work happens. Use the same factual approach to make your work visible before the next review.
