Academics
Students receive specially designed instruction (SDI) aligned to their Individualized Education Program (IEP), with access to grade-level curriculum and flexibility to adjust instruction based on individual learning needs. The program focuses on helping students develop emotional regulation, coping strategies, conflict resolution skills, and positive social interactions to guide relationships, build trust, and foster student confidence and independence. Executive functioning skills such as organization, planning, and time management are embedded throughout daily instruction to support long-term academic success.
Haber Oaks also offers a flexible afternoon program that allows for online learning opportunities for general education students who meet established criteria based on grade level and earned credits. The online program is provided in a small, supportive environment and includes access to paraprofessional support, tutoring, and academic counseling to help students plan coursework and remain on track for graduation.
The curriculum guide provides an overview of courses and academic pathways offered across Community High School District 155. You will find detailed course descriptions designed to support academic planning and career pathways.
Academic Grades
Student grades are reported by semester. Semester grades are calculated based on weighted categories of formative and summative assessments and a possible final exam. Percentages assigned to each category may vary based on the course, with the potential final exam counting for no more than 20% of the overall grade.
Grades are posted and updated regularly in the Skyward online gradebook.
Beginning with the graduating class of 2019, District 155 students will no longer receive a class rank, but will continue to have a GPA.

Standardized Testing
Starting with the 2024-2025 school year, the state of Illinois switched to the ACT for the high school spring accountability exam. This means that all freshmen-juniors are required to take a version of the ACT during the school day in April. Freshmen will take the PreACT9, sophomores will take the PreACT Secure, and juniors will take the ACT with writing. Seniors are excused from school during the testing day(s).
