A selectee receiving a first appointment to the Federal Government (Civil Service) is entitled only to the lowest step of the grade for which selected. The display of a salary range on this vacancy shall not be construed as granting an entitlement to a higher rate of pay.

A Recruitment Incentive May Be Authorized for a newly selected employee when appointed to a permanent, temporary, or term position. A Federal employee who is transferring to the National Park Service from another component, bureau or Federal agency and who does not meet the conditions under 5 CFR §575.102 is not eligible for a recruitment incentive.

This announcement may be used to fill additional positions if identical vacancies occur within 90 days of the issue date of the referral certificate.

Non-Competitive Rehire Eligibility: Temporary seasonal employees can only maintain their non-competitive rehire eligibility if they work no more than a combined total of Temporary NTE less than 1040 hours anywhere in the National Park Service (NPS) within their established service year. Accordingly, non-competitive rehire eligibility allows for re-appointment to the same position or another position appropriate for temporary appointment with the same qualification requirements (5 CFR 316.402[b][7]), based on series and grade, anywhere in the major subdivision (NPS).

If you have held a temporary seasonal appointment in the past 12 months and have already worked the maximum temporary appointment less than 1040 hours during that period, you are still welcome to apply. However, please be aware that exceeding the limit of 1040 hours in your established service year will result in the loss of your non-competitive rehire eligibility.

The limit can be exceeded by working multiple temporary seasonal positions that result in a combined total greater than 1040 hours. The limit also can be exceeded by working a single temporary seasonal appointment that exceeds 1040 hours, unless granted an exception by OPM.

Employment may be terminated at any time due to fluctuations in funding levels, project needs, employee performance, or other considerations.

The National Park Service has determined that the duties of this position are suitable for telework only during an emergency or natural disaster.

Volunteer Experience: Experience refers to paid and unpaid experience, including volunteer work done through National Service programs (e.g., Peace Corps, AmeriCorps) and other organizations (e.g., professional; philanthropic; religious; spiritual; community, student, social). Volunteer work helps build critical competencies, knowledge, and skills and can provide valuable training and experience that translates directly to paid employment. You will receive credit for all qualifying experience, including volunteer experience.

Candidates should be committed to improving the efficiency of the Federal government, passionate about the ideals of our American republic, and committed to upholding the rule of law and the United States Constitution.
