    Principal's message

    Happy holidays, CDOHS Families!

    With less than two weeks of school before winter break, it is important that students continue to work diligently to finish second quarter successfully.  Progress reports have been mailed home, and it is imperative that all students and parents use that information to assess progress in each class. 

    I encourage our Online students to take advantage of the opportunity to work on their courses anywhere they have a device and an internet connection. It’s important that students are working at home at least twenty-five hours a week at home to make progress in their courses. You’re more than welcome to join us in the Café every day in order to have a quiet place to work and get support from teachers!    

    Parents, please continue to monitor APEX Progress Report Emails, and communicate with teachers and counselors if you have any concerns. Also, please help by making sure your student is attending each class on their cohort day and is on time. Cohort-day attendance is critical to your student’s success.

    Second quarter final exams will begin on Tuesday, December 16th and conclude on Thursday, December 19th. We will observe minimum days on final exam days with dismissal at 12:45 p.m.

    Enjoy the winter break, and we look forward to seeing students return on Monday, January 6, 2020.  

    Finally, we wish you a Happy Holiday and a joyful New Year. Best wishes from all of us at the AEC.

    About Us

    The Chaffey District Online High School (CDOHS) is currently enrolling full-time students in grades 9 - 12.  CDOHS, a free public high school is a viable option for many, including homeschooling families that desire to increase the level of rigor of the curriculum available to their students, while maintaining control of the physical learning environment.  Upon satisfaction of graduation requirements, students are awarded a traditional high school diploma from CDOHS and the Chaffey Joint Union High School District.

    CDOHS students benefit from the flexibility that online learning provides including opportunities for course acceleration, unique enrichment programs, online mentors, face-to-face mentors, and access to learning 24 hours per day, seven days per week. All CDOHS original credit courses meet the entrance requirements for the University of California and each AP course has received approval from College Board. Many courses incorporate face-to-face learning sessions, including wet labs in all lab science courses and participation labs for first and second year PE courses.
