How to Correct a Date Error on Your NCOER

A date error on a Noncommissioned Officer Evaluation Report (NCOER) can appear minor, but it may affect the rating period, duty history, evaluation timeliness, and the accuracy of your official personnel record. Common mistakes include an incorrect “Thru Date,” wrong period start date, mismatched change-of-rater dates, or a report that appears to cover the wrong assignment.

The correct response depends on when you discover the problem. An error found while the report is still in progress is usually easier to fix than one found after signatures, submission, or placement in your Army Military Human Resource Record (AMHRR), commonly accessed through iPERMS.

Keep copies of the NCOER, supporting orders, counseling records, and personnel documents that establish the correct dates. A clear record makes it easier for your rating chain, S1, or the appropriate administrative office to evaluate and correct the issue.

Why the Date Matters

The beginning and ending dates define the period being evaluated. They should generally align with the applicable rating requirements, duty assignment, change of rater, relief for cause, or annual evaluation event. A wrong date can create an unexplained gap, overlap another report, or suggest that a supervisor evaluated time outside the proper rating relationship.

Date accuracy can also influence career administration. Promotion eligibility, assignment history, senior rater profile interpretation, and record reviews may rely on the information shown in an evaluation report. Soldiers reviewing their promotion points balance should ensure that their NCOER history is complete and accurately reflected in their personnel record.

Identify Which Date Is Wrong

Start by comparing the NCOER with source documents. Review permanent change of station orders, assignment instructions, leave or absence records, change-of-rater documentation, duty position records, and previous evaluation reports. Pay particular attention to whether the error affects the rating period, the rated NCO’s duty position, or the identity of the rating officials.

Then determine whether the mistake is administrative or substantive. An administrative error is a factual problem, such as a typographical mistake or incorrect month. A substantive issue may involve an improper rating period, an invalid rating relationship, or an evaluation that covers time the rater was not responsible for observing. This distinction affects the correction process.

Fix It Before Final Submission

If the NCOER is still being prepared in the Evaluation Entry System, notify the rater and senior rater immediately. Explain the discrepancy in writing and provide the document that proves the correct date. The rating chain may be able to return the report for correction before it advances through review and signature.

Do not simply change a date on a signed document or create a replacement without coordination. Evaluation reports are official records, and edits made outside the authorized process can create additional questions about document integrity. Ask the unit S1 or administrative support personnel which workflow applies to the report’s current status in EES.

Report status	Practical action	Useful documentation
Draft or returned in EES	Request correction before signatures	Orders, duty records, prior NCOER
Awaiting signatures	Notify the rating chain and S1	Written explanation of the error
Signed but not submitted	Ask whether the report can be returned or voided through the proper workflow	Signed copy and source records
Submitted or filed	Request an administrative correction or appeal review	Filed NCOER, orders, correspondence
Date error affects rating validity	Seek guidance from S1, command channels, or the appropriate HRC office	Complete timeline and supporting evidence

Correct a Signed NCOER

When the NCOER has already been signed, submitted, or filed, begin with the chain of command and servicing S1. They can verify the report’s status and explain whether an administrative correction is available. Depending on the circumstances, the report may need to be returned through an authorized process, corrected by the appropriate office, or addressed through an evaluation appeal.

A signed evaluation should not be altered informally. Keep the original version, identify the exact field or date in dispute, and describe how the error affects the report. If the problem involves the rating period or rating officials rather than a simple typographical mistake, request guidance under the current Army evaluation regulations and personnel procedures.

Build Supporting Evidence

A convincing correction request is specific. State the incorrect date, provide the correct date, explain the source of the correct information, and describe the effect on the evaluation. For example, a change-of-rater order, duty assumption memorandum, or assignment record may establish when the rated NCO actually entered a position.

Organize documents chronologically and retain proof that the request was submitted. Include copies of relevant emails, S1 tickets, counseling records, and the NCOER itself. Avoid sending unrelated personal information; provide enough evidence to establish the timeline while protecting sensitive data.

If the issue involves a senior rater code or potential assessment, review the surrounding record carefully. A guide on how to interpret your senior rater potential code may help you understand why accurate evaluation data matters, although it does not replace official personnel guidance.

Prevent Repeat Errors

Review the administrative portion of every NCOER before signing. Confirm your name, rank, military occupational specialty, duty position, organization, rating officials, “From” date, and “Thru Date.” Compare those entries with your orders and previous report, especially after a reassignment or change of rater.

Raise discrepancies as soon as they appear. Waiting until an evaluation is filed can limit the available correction options and make it harder to locate the officials or records needed to verify the timeline. A short written notice during the draft stage is usually more effective than an unsupported request months later.

Steps for a Well-Supported Correction Request

Use these actions to keep the process organized:

• Save the incorrect NCOER and record its current EES or iPERMS status.
• Mark the incorrect date and identify the exact date that should replace it.
• Gather orders, duty records, change-of-rater documents, and prior evaluations.
• Submit the request through the rater, senior rater, S1, or authorized appeal channel.
• Track the request and verify the corrected report in the official personnel record.

Check the corrected document after processing rather than assuming the change was completed. If the report is stored in iPERMS, confirm that the correct version is visible and that an obsolete version has not created a duplicate or conflicting record.

For related personnel administration, accurate identity records matter as well. Soldiers handling identification updates can review guidance on scheduling a DEERS appointment when a new or updated military ID is needed.

Start the correction process with the evidence in hand, communicate through the proper Army administrative channels, and verify the final NCOER wherever it is officially stored. Acting promptly protects the accuracy of your evaluation history and reduces the chance that a simple date mistake will affect future personnel actions.
