    Happy New Year, CDOHS!

    I hope you had a fabulous, restful Winter Break. It’s wonderful to see you back and energized for a new, productive semester. Make sure you take advantage of each and every day by committing to attending all classes on your cohort days and working online at home for at least 25 hours a week. You’re more than welcome to join us in the Café on your non-cohort days for extra support! Your teachers are here to help you all along the way. Don’t be afraid to ask questions and ask for help! We’re here for YOU!

    Parents, please help your students finish the year strong by monitoring their progress, communicating with teachers, and ensuring your students complete their coursework at home on a daily basis.

    Let’s start and finish the spring semester strong. You got this! Let’s reach our goals in 2020!

    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.
