Standard Form 144 at a glance
What it is: Standard Form 144 is the Statement of Prior Federal Service from the Office of Personnel Management.
Who signs: The Statement of Prior Federal Service is to be completed by the employee.
In order for your employing agency to credit your prior Federal service for benefits, such as leave accrual and reduction-in-force retention, the dates of your active uniformed service and the type(s) of appointment(s) and dates of civilian service must be verified. Dates of active uniformed service are verified from the records issued by the branch of service in which you served. Dates and types of appointments to civilian positions are usually verified from Notifications of Personnel Action (Standard Form 50 or CSC- or OPM-approved exceptions thereto), and payroll records (including records of deductions made under the Civil Service Retirement System-Standard Form 2806, or the Federal Employees Retirement System-Standard Form 3100). The information on the application or resume you submitted for the appointment you are receiving, along with the information on page 2 of this form, will be used by your agency to identify the Federal employers and periods of employment for which records must be obtained to verify the prior service.
What to bring and attach to Standard Form 144
Documentary Evidence: Submit as many as possible of the documents listed in item 1 below. If your agency finds that these documents are insufficient to determine creditability, the documents listed in items 2 and 3 may be considered, but less weight will be given to such evidence. 1. Copies of official documents or letters about the service. These may be notices on appointment/separation; notices of changes in position/salary, organization, or headquarters; travel orders; payroll cards; ID's, etc. 2. Private records such as a diary, correspondence, copies of income tax returns, employment applications, credit applications, etc., that mention the Federal employer and the claimed service. Private records must have been made during or shortly after period of service. 3. Any other documentary evidence tending to prove the service was actually performed and the starting and ending dates of the service.
When Notification of Personnel Action or payroll records cannot be located to verify a period of service, and the service was covered by Social Security, a detailed statement of earnings information (showing periods of employment and the name of the employer) from the Social Security Administration will be accepted as proof of service.

Affidavits and secondary evidence
You are not able to supply sufficient official documents
Affidavit Evidence: If you are not able to supply copies of official documents (as described in item 1) that are sufficient for your agency to make a determination of creditability, you must submit affidavits from yourself and at least two other persons (preferably your supervisors) who know the facts. If you can obtain no documentary evidence (items 1, 2, and 3) to support your claim, you may submit these affidavits only; however, your claim is more likely to be rejected without supporting documents.
The affidavit from the employee states as many of the details on the affidavit as can accurately be remembered. The affidavits are from at least two persons knowing the facts. Each person should show that he or she is in a position to know the facts sworn to, and give his or her age and mailing address.
Affidavits must be sworn to or affirmed before a notary public or other officer who is authorized by law to administer oaths.
Official Government records are lost, destroyed, or incomplete
Secondary evidence may be considered as proof of Federal civilian service only when official Government records are lost, destroyed, or incomplete. Necessarily, the burden of proof is on the person claiming service that is not supported by official records in the custody of the U.S. Government. If you decide to claim credit for a period of service by submitting secondary evidence, it is important that you submit all documents in your possession that tend to prove you performed the service claimed, and that the service, if performed, was creditable for leave accrual and reduction-in-force purposes. No credit can be allowed for any service that is not substantiated by valid and conclusive secondary evidence. The following is applicable only if you are providing secondary evidence.
If no personnel, payroll, or Social Security records can be located, then your agency can accept secondary evidence of civilian employment.
