Principal's Message

Mr. Kirk
Rancho Family,
Thanks to the wonderful work of our staff, student leaders and parent volunteers we are off to a great start to the 2022-23 school year.  A special thank you to our student leadership groups for their role in welcoming back all our Cougar staff and students with great enthusiasm!  
Now that things are beginning to settle down, I want to remind everyone that our staff is here to help our students thrive.  I strongly encourage students to take advantage of all the offerings for support in and out of the classroom offered by our staff including tutoring help for students, opportunities for students to make up credits to get back on track to graduate on time and support our student’s mental health and social and emotional needs.  This includes multiple marriage and family therapists (MFT’s) and Intervention Specialists on site in our student wellness center, as well as our peer counselors and SEL courses offered on our campus.  Our goal is to maintain a safe and welcoming learning environment for every student which is part of our amazing school culture that has made RCHS the number one high school in San Bernardino County per niche.com.
I want all of our Cougars to know that our staff work hard to equip our students with the skills needed to be college and career ready.  However, that success does not sit solely on the shoulders of the school. Success begins with possessing a growth mindset which is the belief that everyone’s intelligence and abilities can improve.  This includes taking ownership of your learning, displaying that Rancho Grit through difficult times and taking advantage of the supports our teachers and staff provide.  With that said, I challenge all Cougars come to school every day on time, complete all assignments and work hard to pass all classes with a C or higher.  By meeting these challenges our students will be in position to meet their A-G requirements.  We know that the skills taught while completing the A-G requirements are key for giving our students multiple options beyond high school regardless of the path they take. 
The state of California measures a school’s effectiveness through the California Dashboard which focuses on five performance indicators.  These indicators are Graduation Rate, Suspension Rate, English Learners Progress, College & Career Indicator, and (CAASPP) ELA and Math Performance Indicators.  Each indicator is scored using a color gauge of five colors (red, orange, yellow, green & blue).  Blue signifies the highest level of performance for an indicator and is the goal for all schools while the color red signifies the lowest level of performance.  Below is a link that has more information on the California Dashboard.
Parents, we want to continue to invite you in as a partner with our school and encourage you to be actively engaged in your child’s success.  To do that, it is imperative that you sign up for your personal Canvas and Parent Square accounts monitor your students’ daily progress, stay in communication with teachers to build and maintain collaborative relationships and attend the parent engagement programs we will offer throughout the year.  
I am extremely excited for what will be a great school year and thank you for all of your continued support! 
Bleed Purple!
Mr. Joshua Kirk
