All Students will graduate ready for college and careers.

Dear Parents and Students,

Thank you for a great start to the 2018-2019 school year! Our staff and students are excited and ready to begin the year strong.

Tigers, making connections is critical to your success in high school. Get to know your teachers, join a club, try out for a sport, and take advantage of as many of the opportunities we have available at Chaffey High School.  Students who get involved tend to be more successful in their classes, know where to go for help when they need it, and feel like school is a safe and supportive environment. 

Another key to success is attendance. It is important that all students be in school every period, every day. This year we are fortunate to collaborate with Metro Honda in the Keys 2 Succeed program. Students who have perfect attendance from August 20th to April 26th will be entered into a drawing to win a brand new Honda Civic LX! For a complete list of contest rules, please see the flyer on our School Loop homepage.

As part of our mission to ensure that ALL students graduate ready for college and career, CHS continues to offer extended learning opportunities. We have after school tutoring Monday-Thursday, ROAR on Saturday, and support and enrichment in the 3rd Period Academy class. Students and parents can also use School Loop to contact teachers and stay informed about progress in classes.

Lastly, I look forward to meeting with parents at our Parent Forum and Coffee with the Principal meetings. This is my chance to share school news and to hear your feedback. The first Parent Forum of the year is Thursday, August 23, from 6pm-7pm in the Chaffey High School  Memorial Library. The first Coffee with the Principal will be on Wednesday, September 5, from 10am-11am in the library.

IMPORTANT: On Monday, August 27th, Chaffey High School will host its annual Back to School Night. Our program will begin with a welcome in our South Gym at 6:30pm. Parents will be dismissed to classes at 6:45pm.

I am looking forward to partnering with you to make this our best year ever! Follow me on Twitter @ChaffeyHSTigers for the latest news or just stop by and say hello whenever you are on campus.

Principal, Chaffey High School
