Calling All Students!

Applications for the 2020 Summer Internship Program

will be accepted beginning January 6, 2020 


The Mercer County Internship Program is designed to provide students in high school and college with paid opportunities to work as well as a chance to gain experience in their field of study. Student internships are offered during summer breaks (June through Labor Day) with a limited number of spots for winter and spring breaks. Mercer County also offers unpaid internship opportunities to assist students looking to earn credits for their college or university. Please refer to page 3 of the Mercer County Student Internship Application for a list of all applicable departments.

During the course of the summer program, students will have the opportunity to take part in a variety of activities hosted by the Office of Personnel, which include a Meet and Greet Networking Lunch, a Panel Discussion comprising Department Directors and Division Chiefs, and volunteer opportunities at local charities. 

Students are expected to comply with Mercer County's pre-employment testing procedures, which include a drug and physical exam and a background check for individuals over the age of 18. Students under the age of 18 must provide working papers in order to be eligible to work. Student interns are expected to comply with Mercer County's residency policy. Students must either reside in Mercer County or attend a school located in Mercer County. 

Students interested in legal internships should visit for more information. The Mercer County Prosecutor’s Office offers opportunities for law school and college students to participate in the operation of a busy and dynamic prosecutor’s office responsible for the detection, arrest, indictment and conviction of offenders against the laws.
