Principal's Message

Christina Martinez, Principal
Dear Students and Families,
 
With less than three weeks of school before first semester finals, it is important that students continue to work diligently to finish the semester successfully. Final progress reports have been mailed home, and it is important that all students and parents use that information to assess progress in each class. Also, please continue to monitor Canvas, and communicate with teachers and counselors if you have any concerns. Please contact the school at 909-988-5560 if you need assistance with creating a Canvas Observer account to monitor your student’s progress.
 
I encourage students to take advantage of our virtual tutoring opportunities, along with meeting with teachers during their morning and afternoon office hours to support learning. Parents, please continue to help students by reviewing their progress each day and by ensuring their daily assignments and homework are complete. Also, please help by making sure your student is attending and participating in each class, every day.
 
This year, we will not have a traditional final exam schedule; instead, the schedule will remain the same:
 
Monday, December 14th Period 2
Tuesday, December 15th
Periods 1 - 3
Wednesday, December 16th Periods 4 - 6
Thursday, December 17th Periods 1 - 3
Friday, December 18th Non-Student Day
 
Even though we do not have a final exams schedule during the last week of the semester (Dec. 14-17), students will still be taking exams and completing projects to demonstrate their understanding of the content and skills learned in first semester. Teachers will communicate with their students about how to prepare for the final exam/project in their class.
 
Finally, I would like to extend well-wishes to our entire Chaffey High School community during this holiday season.  Please enjoy the winter break, and we look forward to starting second semester through distance learning on Monday, January 4, 2021. Please stay connected by checking our school website throughout the winter season.
 
Go Tigers,
 
Christina Martinez
Principal, CHS
