O'Neill is fortunate enough to have two outstanding schools systems: O'Neill Public Schools and St. Mary's Schools. A new satellite campus of Northeast Community College is also located on the east side of town. In addition, toddlers are able to attend preschool in town.
O'Neill Public Schools
The O'Neill Public School District serves approximately 750 students K-12. It covers 665.1 square miles and has five attendance centers: a K-6 elementary, 7-12 Jr./Sr. High, Alternative Ed, Emmet, and Inman. The district offers a variety of services including Title 1, SPED, HAL, and ELL. High school students may enroll in some classes for both high school and college credit. The implementation of the 1:1 Learning Initiative gives 7-12 students access to a Mac Book 24/7 during the school year. About 55% of O'Neill's graduates continue their education at a four year college. Other post secondary schools receive another 30% of the graduates, while the remaining 15% enter the work force or join the military.
