District 99 Summer School 2022

District 99 offers two three-week semesters over the summer to provide opportunities for students who:

  • Need to repeat a course in order to complete requirements for graduation and to earn credits.
  • Want to repeat a course in order to increase understanding and grade replace previous grade.
  • Choose to enrich and/or accelerate their regular programming
  • Desire additional flexibility in scheduling courses for the regular school year


Summer School for the 2022 school year will be held at South High School.

Bus services are offered to all District 99 students, regardless of if they currently attend Downers North or Downers South.

  • Semester 2: June 27- 30, July 5-7, 11-14 (3-week block, 11 days total)

Most classes meet from 8:00 am – 2:00 pm on the days listed above.

Exceptions are: Drivers Ed, Keys to Academic Success, and AP Chem Prep.

Please see course descriptions for exact times. 



All students are expected to observe the regular school rules, as stated in the district handbook. Regular attendance is mandatory because each class represents a significant portion of the total class time. Vacations, training camps, or competitions are not valid reasons for absences. 

If a student is absent more than two days per semester, regardless of reason, the student will be dropped from the class with no refund of tuition or fees. Additionally, three tardies accumulate to count as one absence.


Final Exams will be conducted on June 23 and July 14 during the later half of the day.  Final Exams will not be allowed prior to these days.
