The District's well-prepared, dedicated, and highly qualified teachers and support personnel are second to none.
The Chaffey Joint Union High School District Board of Trustees are steadfast in the belief that "Nothing is more important than student learning and their achievement."
Our daily purpose encompasses our commitment:
"To provide student learning, and ultimately their achievement, of the prescribed curriculum that takes place in the classroom under the direction of the teacher." The Chaffey District supports this daily act. We realize that our efforts uniquely influence the future of our community and of this nation, and we are passionate about doing whatever it takes to prepare students to be successful and contributing citizens of the 21st century.
The Chaffey District has provided a quality education for high school students in the area since 1911. As the District continues to grow and progress, we are poised to meet the challenge of providing the finest quality education possible for every student.

Principal's Message

Julie Prestsater, Principal
Dear Alternative Education Center Students and Families,
We are halfway through the second semester! Where did the time go?
Opportunity. Connection. And grace. These are words that come to mind when I think of this year. Students, you have embraced new opportunities to persevere during this challenging time. You have made connections with faculty and staff to ensure your success in distance learning, both academically and social emotionally. You have also shown grace to faculty and staff as well as yourselves and your classmates as we have navigated this journey together. I hope you are proud of what you have accomplished under these trying circumstances. And now, we must change course again and embark on exciting times as we are able to safely return to campus. I can’t wait to see you!
San Bernardino County is approaching a less restrictive COVID-19 red tier, which will allow for the reopening of high schools for in-person hybrid instruction. In-Person Hybrid Instruction will begin the week of April 12th, depending on school and program schedules.
Students and families will have the option to choose:
1.       Hybrid Instruction: Students attend school On Campus and On Zoom for instruction, or
2.       Distance Learning: Students will remain in distance learning for virtual instruction on Zoom.
For more information regarding the Reopening Plan for all Alternative Education Center schools and programs, please click here.
We are also approaching the academic testing season, the administration of the Smarter Balanced Assessment Consortium (SBAC) and English Language Proficiency Assessments for California (ELPAC). We recognize the significant impact that the COVID-19 pandemic has had on student learning and simply encourage our students to do the best that they can. At this time, it is unknown how student achievement data will be reported and analyzed due to the suspension of the CA Dashboard in 2020.
The school year is not over. With one quarter left, I encourage AEC students to stay strong and determined to succeed. We are here to support you in any way that we can and look forward to seeing you in April!
Your proud principal,
Mrs. Prestsater
