Federal Temporary Appointments

Federal Temporary appointments are considered as Administratively Determined (AD) appointments. Individuals appointed to a Federal Temporary appointment do not require an affiliation with an institution.  All appointees must be a US citizen or an individual lawfully admitted for permanent residence and is pursuing U.S. citizenship. In order to be considered for federal appointments, Non-Citizens must affirm that they meet the Appropriations Law eligibility criteria by signing and attaching this Citizenship Affidavit to their application. Non-Citizens who do not provide the affidavit at the time of application will not be considered. Non-Citizens who are exempt from the Appropriations Law requirements due to their status as officers or employees of the U.S. government on December 16, 2009 must provide with their application a statement noting their exemption and proof of status their U.S. government employee or officer status. The Division of Human Resource Management (HRM) will determine eligibility for non-citizens.

Appointments are usually up to one year and may be extended up to an additional two years by mutual agreement between NSF and the appointee. AD-1 appointments are limited to two years total.

Salary is set within a range for "Administratively Determined (AD)" level positions, using pre-established criteria. Salary is based on AD Level and qualifications for the subject position. The total salary cap is top of the AD level of position to which appointed.  AD salary adjustments are based on the annual federal pay increases.
