Academic curriculum will generally be organized in, approximately, four - ninety (90) minute blocks of instruction daily. The academic core classes will contain alternative materials and curricula aligned with Idaho State Department of Education standards, distinct from those offered by conventional high schools. Heartland High School will utilize the adopted McCall-Donnelly School District Curriculum. Academic core curriculum may also be delivered online using web-based programs. The instructional staff will carefully monitor course content to ensure that the curriculum objectives for each subject are met and mastered by students before credit is granted. In all cases, completion of approximately 60 hours of instruction plus necessary homework and research are required.

Heartland High School runs on a "Quadmester" system with classes meeting every day. Semester-long classes are completed each quarter.
