Summer School
Students can take a variety of classes during the summer. If you are interested in in Summer School, please understand that students must reside in District 155 boundaries and meet other requirements in order to be eligible for enrollment. With the exception of driver’s education courses, all summer school courses will be held at Cary-Grove High School located at 2208 Three Oaks Road, Cary, IL 60013. The main office number is (847) 639-3825. Driver’s education courses meet at the student’s home school.
A variety of special education courses and programs are offered during the summer. Information regarding Extended School Year-Special Education will be mailed to families after spring break.
Any student who plans to attend summer school—including students with an IEP—should contact the student services department at his/her high school and register as soon as possible.
