New guaranteed admission agreement signed with ULV!

In an effort to provide even more advantages for the graduating students of our District, Superintendent Mathew Holton and University of La Verne President Devorah Lieberman recently signed our new admission agreement!  All CJUHSD graduates who meet the minimum requirements, will be able to enroll and attend this prestigious private university.  One of the amazing highlights of our new agreement is the commitment of ULV to provide a minimum scholarship of $5,000 to all our students!  This is the first guaranteed admission agreement our District has reached with a private university, and we are very excited about the opportunity for our students to attend this highly acclaimed local university.  This agreement, along with the previous agreements with Cal State San Bernardino, Cal Poly Pomona, and Cal State Bakersfield continue to provide an advantage to the students of the Chaffey Joint Union High School District to pursue their dreams for the future!
