DECA
DECA is an organization of marketing students at Mosinee High School. Important events include a yearly trip to a Wisconsin Badger's Hockey game to learn about sports marketing, and a yearly trip to Six Flags to learn about event marketing. There is also a DECA Competition that students participate in to show off their business skills on tests and "Role Plays" with a judge. There are even state and international competitions.

Library Club
The Mosinee High School Library Club is for those who believe reading is an integral part of growing and learning. We promote reading at all levels, but especially promote for high school students to read books for pleasure, not just assigned reading. We want students to develop a passion for reading to carry beyond high school and even college.

Our services to the school include a student store, a copy machine for student use, various sponsored events (Banned Books Week, Teen Read Week, and Battle of the Books) and supplying magazines/references to study hall.

National Honor Society
The purpose of National Honor Society is to recognize students who excel in school and the community. NHS was founded in 1921 to recognize and encourage academic achievement while also developing other characteristics essential to citizens in a democracy. To be eligible for membership consideration, students must have a cumulative GPA of 3.5. In addition, candidates must meet high standards of leadership, service, citizenship, and character. To be eligible for membership a candidate must be a member of the sophomore, junior, or senior class. Candidates must fill out an application after the first semester, which is then evaluated by a faculty advisory council. An induction ceremony takes place in the late spring. All members are required to spend a minimum of 20 hours in community service throughout the school year (hours must be documented). As a club we participate in such advisories as: Pen Pals with elementary students, Big Brothers/Big Sisters, raising funds for the homeless and St. Jude's Children's Hospital, adopting a family at Christmas, and donation of food to the local food pantry. Members must sign a Code of Conduct, agreeing to the standards of NHS.

Outdoor Club 
Students determine what they want to do. Involves 3-4 weekend trips and participation in an annual Ice Fishery.

Student Senate
Student Senate is a school and community service organization made up of Senate and class officers, operations committee members, appointed chairmen and a representative of each of the other clubs and organizations of MHS. We organize a number of student activities at MHS including homecoming week, fire and ice week, blood drives, Evening of Elegance and Lunch with the Easter Bunny among others. Our priorities are: leadership training, school and community service and scholarships, in that order.

Teens Need Teens (TNT)
TNT is a club where teens with and without disabilities become friends. We meet weekly during enrichment to play games and plan a monthly out of school activity. Our monthly field trips have taken us to River Park for a picnic and games, Trick or Treating for UNICEF, a fall hayride, a movie night at a students’ house, ice racing on Lake DuBay, bowling and fishing. The students have all benefited from the friendships that were formed. The club is advised by Mrs. Brandt and Mrs. Klinger.
