Diamond Bar High Summer School Programs

 DBHS offers three (3) different summer school programs on our campus:


I. WVUSD Non-Tuition Remediation of D's/F's Graduation/CSU/UC or Enrichment

WVUSD non-tuition classes are for students who need to retake a course for high school graduation credits. Class rosters are generated by the student's GLC. Please see your GLC if you believe you need to retake a class during summer school. These classes are offered to current 9th, 10th, and 11th grade students. 


II. Non-Tuition Courses for Advancement or Remediation for Graduation/CSU/UC

Mt. SAC non-tuition courses are for students who wish to advance in a subject area. There are limited course offerings and seats available; all Mt. SAC class rosters are determined by a lottery system. These courses are offered to our current 11th, 10th, and 9th students (in that order) and current 8th grade students who will be DBHS 9th grade students in the fall of 2024.  Please click on the tab to the right to find out about course offerings and apply for a seat. 


III. Dedicated to Learning Tuition Program

D2L (Dedicated to Learning) courses are tuition based classes for students who wish to advance in a subject area. Visit the D2L Website for program details using the link provided on the tabs to the right (in February). 


WVUSD and Mt. SAC class information will be posted on pages I & II.

D2L class information will be posted on page III.
