Vision
Inspire All to Achieve their Very Best!
Students enter North Hills Middle School as young boys or girls and in three short years are prepared to accept the academic rigors expected of high school students. This great change in knowledge, attitude and responsible behavior comes about through the efforts of many. Students and parents are part of a family at North Hills Middle School, whose members, by working with one another, are dedicated to providing quality learning experiences for all students.
