The Chaffey Joint Union High School District is proud to introduce you to the premier, free, public online learning opportunity in the Inland Empire.  As the 9th school in the district, the Chaffey District Online High School brings an innovative learning opportunity allowing student learning to reach across several dimensions. Understanding not all students learn in the same fashion, CDOHS will offer learning opportunities tailored to the individual needs of the independent learner.

Knowing the benefit of online learning, and its various models, is the drive of our staff to adhere to the goals of the district:  Increase Student Achievement and Improve Instruction; utilizing innovative methods.  The online learning opportunities of CDOHS are aligned to the requirements of the UC/CSU bound student as well as those desiring to graduate from high school with a traditional diploma from the Chaffey Joint Union High School District.  We also address the needs of credit recovery as well as grade remediation for some course work. 

Chaffey District Online High School is proud to be offering a free, public education to the students in San Bernardino, Inyo, Kern, Los Angeles, Orange, and Riverside counties.  We look forward to partnering with you to ensure our school is the best it can possibly be.  With online learning becoming a popular option of innovative learning we look forward to serving such needs.

Dear AEC Families and Students,

We are just one quarter away from the end of the school year and GRADUATION DAY! I encourage students to finish strong by putting in the time and effort needed to successfully cross the finish line.

Upon our return from Spring Break, the entire Alternative Education Center will embark on testing season, so please review the upcoming schedule of assessments. Our teachers and students have been working thoroughly to prepare for SBAC tests, as well as AP exams. The SBAC will be administered to measure the achievement of all juniors in the subjects of mathematics and English, while seniors will be assessed in science. In May, our Chaffey District Online students will be taking AP exams in the areas of English Language and Composition along with Statistics and Calculus. Students are prepared, and they are ready. We’re very proud!

As a first-year principal, I have learned so much from each and every one of you and I have truly enjoyed every minute. Our work is not done, though. Parents: join me for Coffee or Popcorn with the Principal, or call, email, or stop by so we can chat about what’s happening at the AEC. Students: attend classes regularly, be on time, and be ready and willing to work. And don’t forget to ask questions, ask for help… not only in regards to academics, but for anything we can provide you support. We are here for you!

Let’s continue to champion the remainder of the school year together.

Mrs. Prestsater

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.
