Greenville Middle School opened its doors in the fall of 2002 for the first time to approximately 375 grade 5-8 students. Most students attending Greenville Middle School attended Greenville Elementary School which is situated right next door to Greenville Middle School. Approximately 520 grade 5-8 students will attend GMS for the 2007-08 school year. 

In addition to a five hour core academic block, extensive curricular offerings are available to our students. They include, two foreign languages, computer education, art, health, physical education, band, chorus, chorus and music lab. 

Depending on a student's grade level, co-curricular activities such as: football, basketball, track, cross country, volleyball, wrestling, student council, forensics, yearbook, newspaper, show choir, jazz band, and many others are also available for students to participate in during and after school. GMS has combined teams with their sister school Hortonville Middle School in track, cross country and wrestling. 

Honor Level Discipline is an incentive program which recognizes students for good behavior. It provides awards for students who make good choices. It also provides consistent and fair consequences for students who make poor choices. The primary purpose of this program is to help each student grow towards becoming a responsible adult.

Greenville Middle School recognizes that successful students are encouraged and supported when the school, parents, student, and community all work together.
