About Us

The Chaffey Joint Union High School District serves the communities of Ontario, Montclair, Rancho Cucamonga, and portions of Fontana, Upland, Chino, and Mount Baldy. With over 25,000 students, the District is the fourth largest high school district in California. It has eight comprehensive high schools, a continuation high school, an online high school, a community day school, an adult school, and alternative programs. The District offers a wide variety of instructional options that provide a quality education for each student, every day. 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.

Dear AEC!
It’s been an honor to serve you as the Principal for the Alternative Education Center. I’m so proud of our students and staff at Valley View, Chaffey District Online, Community Day, CSOP, GED Renew, and DASP. We have accomplished so much this year despite all the challenges and uncertainty. You have persevered and you have remained strong!
We are near the end of the school year with our last day being on Thursday, May 20th, 2021. Our graduation ceremony schedule is below:
Chaffey District Online High School

• 5:00 p.m.
Valley View High School

Important: Participation in the ceremony does not mean students are official graduates. Some students will need to take summer school to complete graduation requirements and receive a diploma. Students who need to take summer school classes or apply for a 5th year can do so by clicking on the links below.

Finally, I would like to take this opportunity to say thank you to our staff, students, and parents and guardians. Although we were confronted with historical challenges beginning the year with distance learning, and now hybrid learning, our students and staff have given their best efforts to learn, grow, adapt, and succeed. We are who we are because of your dedication to making the AEC a wonderful place. I am so proud to be your principal and I look forward to all we can accomplish together.
Mrs. Prestsater
