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 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. Parents and guardians receive email notifications at each progress report (3 times a semester). 

Beginning with the graduating class of 2019, District 155 students will no longer receive class rank, but will continue to have a GPA.
