Summer School


Students enrolling for grade replacement MUST have a counselor and an Administrators approval before registering for classes. Please complete this FORM for grade replacement.
Summer courses are intended for students who need to regain lost credits or to stay on track for graduation and is not intended for students who wish to 'get ahead' or 'bump' their GPA (i.e., from a 3.9 to a 4.0).
The attendance policy is set by the Colorado Department of Education and allows three absences in any course (3 tardies = 1 absence), after which students will be withdrawn from summer school and will receive a failing grade, no credit for the course(s) and will forfeit registration fees. Students who do not complete a course within the allotted time for each session will also receive a failing grade and no credit for the course(s) and forfeited registration fees.
It is the student’s responsibility to check with their counselor that the courses taken in summer school meet their home school’s requirements for graduation, replacement credit, and the desired impact of the course on their GPA. Please check with your assigned high school counselor to ensure you register for the appropriate course(s).
Students not completing a course within the allotted time will receive a failing grade and no credit for the course(s). Any breach of conduct can result in removal from the program and forfeited fees. Click here to review summer school guidelines.

GRADE REPLACEMENT: A record of both classes, along with the grades received for both classes, will remain on the student's transcript. The class taken during the school year will show "course repeated"; no credit will be awarded and will not be calculated into the student’s GPA. The summer school course/s will receive credit and will be calculated into a student's GPA. Grade replacement courses are 60+ hrs and require at least 4-5 hours per day, 5 days a week to complete. NCAA approved.

CREDIT RECOVERY: A record of both classes will remain on the student's transcript. Credit will be awarded for both classes, one will be an elective credit, and both grades will be calculated into the GPA. Courses taken for credit recovery are not approved by the National College Athlete Association. Credit recovery courses can easily be finished within each summer school session as students can pretest and move quickly through sections of curriculum. Not NCAA approved.


Registration links coming soon! It is strongly recommended that students limit registration to 2 courses per session due to work loads and time constraints. Once class fees have been paid students will receive login information for classes by the first day of class, or soon after payment has been received. Course fees must be paid in full before students receive login information for courses.
