Chaffey District Online High School


Dear CDOHS Students & Families,

Welcome to Chaffey District Online High School for the 2017-2018 school year. I hope you had a fantastic summer and are as excited as I am to kick off another amazing year. Words cannot adequately express how honored and humbled I am to be the new Principal of the Alternative Education Center, which includes CDOHS. I am fortunate to have spent the last four years in alternative education learning from CDOHS students, parents and guardians, and faculty and staff. I look forward to serving you as we work toward achieving our goal for all students to graduate ready for college and career!

We have high expectations for our Online students as they navigate a computer-based instructional model with the support of their teachers. This blended learning approach affords students every opportunity to graduate with a high school diploma having met the entrance requirements for a four-year university. Students have access to their coursework 24 hours a day, 7 days a week with an internet connection—so with hard work, determination, and motivation, every student can achieve success.

CDOHS Parents & Guardians—you play an important role in the success of your student. We offer many ways for you to monitor the progress of your student so you can provide that consistent feedback and motivation they need to stay focused. School Loop is an amazing tool available for you to monitor quarter grades and course completion. It is also a fabulous avenue to communicate with teachers. APEX progress reports will provide you with academic progress so you can view the quality and quantity of work your student is mastering on a daily basis. Together, School Loop and APEX tools are a great resource for you to ensure your student is continually making progress.

It is vital that we all work together to make a high school diploma a reality for our students. We invite all parents and guardians to join us for a variety of parent meetings and groups throughout the year! We truly cherish the relationships we are able to build with our CDOHS families.

The 2017-2018 school year will kick off on August 7th with Freshman Monday. School begins promptly at 8:35 a.m. every day for each grade-level cohort day. Grade-level days are as follows: Freshman Mondays, Sophomore Tuesdays, Junior Wednesdays, and Senior Thursdays. As always, the Café will be available to students on a daily basis for a place to work or connect with their teachers for support.

I’m looking forward to an amazing school year filled with promise, hope, and making our students’ dreams come true.

Operation Clean Sweep


Chaffey District Online High School is proud to introduce a partnership with the Ontario Police Department through Operation Clean Sweep.  The philosophy behind Clean Sweep is to work together to reduce juvenile offenses on school campuses, to foster a spirit of cooperation between the police and schools, and to increase campus safety.  Administration and Campus Safety Officers are trained to recognize specific juvenile infractions and utilize the Juvenile Citation Program.   Students will face a judge who may impose a fine, community service, and/or counseling classes.  These penalties are in addition to whatever disciplinary consequences are imposed by the Online High School administration. Behaviors that can result in a citation are:

  1. Truancy
  2. Possession or use of tobacco (or products)
  3. Littering
  4. Fighting or disturbing the peace
  5. Keeping property
  6. Petty Theft
  7. Minor in possession of aerosol paint can
  8. Affixing graffiti
  9. Under the influence of alcohol or marijuana
  10. Possession of alcohol
  11. Possession of marijuana

Operation Clean Sweep is a multifaceted program that seeks to enhance the security of all students in school while, at the same time, establishing responsibility, discipline, and accountability in respect to student’s actions.
