Frequently Asked Questions

  • Interns receive college credit for their experience, while externs do not. If the student’s college offers credit for internships, it is the student’s responsibility to arrange for the credit. We require a minimum of 20 hours per week for a minimum of six weeks for internships, and a minimum of 15 hours per week for a minimum of six weeks for externships.

  • No. All intern/extern positions are unpaid with no housing provided.

  • Interns/externs can be employed on a part-time basis by the Zoo during their internship/externship; however, they cannot intern/extern and work in the same area.

  • We do not accept internship/externship applications after the posted deadline. We do accept interns and externs each spring, summer and fall, so we encourage you to apply for a future semester.

  • Application materials are collected by Volunteer Services. Volunteer Services does not release submitted applications to hiring managers until the application deadline. After that date, applications are accessible to the hiring managers of the preferred areas indicated on your application. Qualified applicants will be interviewed and selected by curators or department managers. Processing time can take up to 8 weeks from the application deadline, as your application may be shared with several program areas (not only your first choice). All applicants will ultimately be notified of a decision by Volunteer Services.

    Due to the volume of applications, emails and phone calls to Volunteer Services are discouraged as we are unable to check on application statuses. Thank you for your understanding.
