Principal's Message

Christina Martinez, Principal
Dear Parents and Students,
Welcome to Chaffey High School, home of the Tigers, for the 2020-21 school year. I hope you had a safe and restful summer despite the challenges we are facing due to the Covid-19 pandemic.
We begin the 2020-21 school year with some big changes. Change is always a little scary, but it can trigger amazing growth. Let’s take advantage of these changes, and together, turn them into opportunities to take Chaffey High School to the next level!
One of our biggest changes is that we will begin the school year in a distance learning model. Students will need to register in Canvas, our new learning management system, to access their classes. Information on how students and parents can register for Canvas can be found on our website.
What is a distance learning model and how does it work?
Distance learning means instruction in which the student and instructor are in different locations. This may include interacting using a computer and communications technology.
What will the opening days of school look like?
The first day of school is Wednesday, August 5th. On this day, we will have a unique schedule. Students will log in to Canvas and check-in with their teachers in 20 minute blocks. See the schedule below for exact times.
Wednesday, August 5th Student Check-In Times

Beginning on Thursday, August 6th and Friday, August 7th, students will log in to Canvas to attend school virtually in a block schedule. Teachers may schedule virtual in-person instruction and/or independent learning and/or learning in groups.  Moving forward, this will be the same schedule that students have Tuesday-Friday while we are in a distance learning model.
