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.

In an effort to ensure consistency in grading practices, the following grading scale is used throughout all courses.

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).
