Career academies
Mountain Home High School operates using the academies model. Students are divided into academies based on their interests and learning styles. Each academy consists of core classes and elective classes unique to each academy. Students may choose electives from other academies, but are encouraged to follow a "completer" path within their own academy. Teachers are also split into academies, theoretically according to their strengths.
