Guaranteed Admission Agreement Signed!

In our continuing efforts to provide every advantage to the students of the Chaffey Joint Union High School District, Superintendent Mathew Holton and Cal Poly Pomona President J. Michael Ortiz signed an agreement guaranteeing admission for all CJUHSD graduates who meet the minimum requirements for enrollment. The highlights of the agreement include guaranteed admission, a four-year graduation pledge, and additional support and information for our graduates. This agreement follows a similar memorandum previously signed with Cal State San Bernardino and gives our students priority over other applicants at both of these outstanding universities.
