    Principal's message

    Hello Jaguar Family!

    We are near the end of the school year and our students will take their finals very soon!  We will have our graduation ceremony in our beautiful Jaguar Stadium on May 23 at 6:30 p.m.

    As students prepare for finals, we will continue to have after school tutoring and the library is open until 4:30, Monday-Thursday.  Our cafeteria also provides a snack to students who attend tutoring!

    Please see the finals schedule on this page and keep in mind that we dismiss early on May 21, 22, and 23., school will end at 11:50 a.m. on those days.

    I want to thank you for supporting our school and most importantly for supporting your son/daughter.  Our students have accomplished a lot this school year, and I am certain that they will properly prepare for their final exams. 

    Have a great summer and we will see you on the first day of school, August 7th!  Congratulations to the class of 2019, we are proud of you!

    It is an honor to be your principal!

    Cal Baptist signing MOU with Mat Holton

    guaranteed admissions agreement signed with cbu!

    Mathew Holton, Superintendent, and California Baptist University Provost, Dr. Charles Sands, recently signed our newest admission agreement! All CJUHSD graduates who meet the mutually agreed upon admission requirements, will be able to enroll and attend this progressive university. One of the amazing highlights of this agreement is the commitment of CBU to provide a minimum of $8,000 per academic year in combined scholarships and grants to all our students! We are very excited to provide this opportunity for our students to attend this university in Riverside, California. This agreement, along with the previous agreements with Cal State San Bernardino, Cal Poly Pomona, Cal State Bakersfield, University of Redlands, University of La Verne, Azusa Pacific University, and Grand Canyon University continue to provide an advantage to the students of the Chaffey Joint Union High School District to pursue their dreams for the future!
