The Ontario-Montclair School District High School Credit Program (HSCP) provides eligible 8th grade students the opportunity to begin earning high school credits while attending OMSD middle school or K–8 sites through a partnership with Chaffey Joint Union High School District.

As the first K–8 district in the region to offer this opportunity, OMSD allows students to take select high school–aligned courses, including Integrated Math I and Spanish I or Spanish IIS, with course availability varying by site. HSCP courses are aligned to high school standards, count toward CSU and UC A–G requirements, and are designed to support students in accelerating their academic pathway while preparing them for a successful transition to high school and postsecondary goals.
