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.

Principal's Message

Julie Prestsater
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 state tests which will be administered to measure the achievement of all juniors in the subjects of mathematics and English, while seniors will be assessed in science. Students are prepared, and they are ready. We’re very proud!
This year, 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: continually check your student’s progress online, 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 about academics, but for anything we can provide you support. We are here for you! We care you!
Graduating seniors & families, please check your email often so you do not miss important graduation announcements.
Let’s continue to champion the remainder of the school year together.
Mrs. Prestsater
