Common Mistakes That Undermine Your COER Rebuttal

A Career Opportunity Evaluation Report (COER) is an official assessment used in federal service, and when the results aren’t favorable, a rebuttal can be submitted. This rebuttal is your chance to address inaccuracies, respond to unfair characterizations, and highlight your performance.
At The Law Office of Shannon James PLLC, I help individuals in Washington, DC approach their COER rebuttal with a clear strategy. Missteps in tone, structure, and supporting evidence can weaken the response.
When I represent clients during a COER rebuttal, I often see patterns in how responses are written. Understanding these common mistakes is key to strengthening your case. Contact me today to learn more or start building your rebuttal with an experienced COER attorney.
One of the most frequent issues I see is poor organization. A rebuttal that jumps from one thought to another without a clear flow can confuse the reviewer. Even if the content is strong, a scattered presentation can make the argument less persuasive
I recommend starting with an outline before writing. Think about the key issues you want to address and the order that makes sense. Presenting your points logically shows that you’ve taken the time to prepare and that your response is thoughtful. A simple structure might include:
Identifying the contested points in the COER.
Presenting supporting evidence or counterexamples.
Explaining the relevance of the evidence.
Concluding with a professional and respectful tone.
This kind of structure not only makes your rebuttal easier to read but also highlights the strength of your arguments.
Another common mistake is leaning too heavily on emotion. I understand how personal a COER can feel, but a rebuttal isn’t the place for anger or frustration. Statements that sound defensive or accusatory can work against you. Instead, focus on evidence.
If a supervisor claims your work wasn’t timely, include examples of projects completed ahead of schedule. If your communication skills were criticized, provide documentation of successful collaborations or positive feedback from colleagues. Facts demonstrate reliability. Emotion, while valid, rarely convinces a reviewer on its own.
Too often, rebuttals are written without documentation. Simply stating that a COER is inaccurate doesn’t carry as much weight as providing records, reports, or performance reviews. Without documentation, you’re asking the reviewer to rely solely on your word. I advise clients to gather as much supporting material as possible. That could include:
Emails confirming successful project outcomes.
Records showing deadlines met.
Copies of awards, commendations, or acknowledgments.
Witness statements from colleagues or supervisors.
The more relevant documentation you can include, the stronger your rebuttal becomes.
Sometimes, individuals write rebuttals that only give general statements like “I disagree with this evaluation.” While that may be true, vague rebuttals don’t help your case. A rebuttal should address specific claims in the COER. If the report says you lack leadership, identify moments when you supervised a project, trained colleagues, or stepped into a leadership role.
Another mistake is submitting a rebuttal without a careful review. Typos, grammar mistakes, or unclear sentences can create the impression of carelessness. A rebuttal should reflect the same professionalism you show in your daily work. Before submitting, I recommend:
Reading your rebuttal aloud to catch awkward phrasing.
Asking a trusted colleague to review it for clarity.
Double-checking all dates, names, and references.
That extra time reviewing can make a difference in how your rebuttal is received.
Deadlines are critical. Submitting a rebuttal late can sometimes mean losing the chance to respond entirely. I’ve seen individuals craft strong rebuttals but submit them after the deadline, and their work went unheard. Mark deadlines immediately upon receiving the COER. Plan backward from the due date so you have time to draft, collect documents, and review.
A COER rebuttal is more than just a personal response—it can have long-term implications for your career. Many individuals try to handle the process entirely on their own and miss opportunities to strengthen their rebuttal.
Legal guidance can help identify weaknesses in the COER, highlight areas where evidence is most effective, and assist in structuring a persuasive argument.
Minimizing the Significance of the COER
Some individuals underestimate the impact of a COER. They think it’s just paperwork, but these evaluations can affect career progression, future assignments, and even long-term opportunities.
Treating the rebuttal as a serious process shows respect for your own career. A thoughtful and well-prepared rebuttal communicates that you care about your record and your performance.
Overemphasizing Minor Issues
It’s tempting to address every single word in a COER, but focusing on minor details can distract from your stronger points. For example, if the COER contains a small factual error that doesn’t impact the evaluation, spending too much time on it may take attention away from bigger issues. Prioritize the areas that matter most to your career record.
Overwriting or Rambling
While detail is important, writing too much can also be a problem. Long rebuttals filled with unnecessary background or unrelated information can lose the reviewer’s attention. Your rebuttal should be clear, concise, and directly tied to the COER comments.
Short paragraphs work better than long ones because they’re easier to follow. Use plain language rather than technical jargon unless it’s absolutely necessary.
Ignoring Positive Aspects
A rebuttal shouldn’t only address negative comments. Sometimes individuals forget to highlight the positive parts of their record. If the COER includes favorable remarks, reference them in your rebuttal to demonstrate balance. For example, if the report says you need improvement in one area but praises your leadership, acknowledge that praise while addressing the criticism.
Disregarding Confidentiality
Some individuals mistakenly share rebuttal drafts too broadly, such as sending them to multiple colleagues for input. While feedback is helpful, confidentiality is important. Too many people involved can lead to unintended disclosures or workplace tension. Limit sharing to trusted individuals or legal counsel. Keeping the process controlled helps you avoid complications.
Treating the Rebuttal as a Personal Attack
It’s natural to feel defensive when faced with a negative COER, but treating the rebuttal like a personal battle against your supervisor doesn’t help. Reviewers are more persuaded by facts and documentation than by personal disputes. Frame your rebuttal as a professional response rather than a conflict. This keeps the focus on your record and performance.
Not Following Formatting Guidelines
If your agency provides guidelines for rebuttals, follow them carefully. Sometimes individuals ignore word limits, font requirements, or submission formats. Doing so can delay or even disqualify a rebuttal. Always review the submission requirements before finalizing your document. Meeting technical expectations shows attention to detail.
Neglecting Professional Tone
Tone matters. A rebuttal that sounds hostile or sarcastic can damage credibility. I’ve read drafts where individuals used phrases like “this is clearly biased” or “my supervisor doesn’t understand my role.” While those feelings may be real, that language isn’t productive in a rebuttal. Keep your tone respectful and professional.
Overlooking the Long-Term Impact
Finally, many individuals see the rebuttal as only about correcting one report. In reality, the rebuttal becomes part of your personnel file and may be reviewed later in your career. How you present yourself now can shape future opportunities. Think beyond the immediate correction.
A COER rebuttal is your chance to protect your professional record and clarify your performance. Avoiding mistakes like poor organization, emotional language, missing documentation, or deadlines helps you present a stronger case. A carefully prepared rebuttal reflects professionalism, attention to detail, and dedication to your career.
