Principal's Message

Eduardo Zaldivar, Principal
Dear Cougar Community: 
Welcome to the 2020-2021 school year! The first days of school are always filled with excitement and anticipation, but with COVID-19 challenges and a temporary Remote/Distance Learning Schedule to begin the year will make this a year one we have never experienced. Students will meet remotely to begin the year, periods 1,2, 3 will meet on Tuesday and Thursday and 4,5, and 6 on Wednesday and Friday.  On Mondays, students will meet with their 2nd period class for 20 minutes. Please see our website for specific times, under “Bell Schedule.” 
You will be proud to know that we are the top public high school in San Bernardino County as deemed by Niche.com!  We have also been named as one of America’s best high schools by US News and World Report and the State of California's Department of Education has designated us as a Gold Ribbon School.   Needless to say, we have a rich history in academics, athletics and extracurricular programs.  We have much to be proud of, but we also recognize that there are areas in which we need to improve upon and we will work collaboratively with our school community to address issues of equity and access for students. Together, we will help our students succeed!  

Even with the challenges that lie ahead, I am excited to begin the year with you.

Principal and Graduate of RCHS
