Principal's Message

Mr. Kirk
Rancho Family,
I hope you all enjoyed a safe and restful Thanksgiving break. With less than four weeks of school before first semester finals, it is important that all Cougars continue to work diligently to finish the semester successfully.  Progress reports have been sent home electronically via Parent Square, and it is imperative that all students and parents use that information to assess progress in each class.  Also, please continue to monitor Canvas and Parent Square while communicating with your teachers and counselors if you have any concerns. Please contact our school at (909) 989-1600 if you need assistance with creating a Canvas Observer account to monitor your student’s progress.
I encourage students to take advantage of our tutoring opportunities including the 24/7 Paper tutoring services each student has access as and attending our final three GOAL Saturday Schools this semester which are on December 3rd, 10th, and 17th from 8am-12pm on our campus.  Our Link Crew leaders will in attendance for the Saturday School on the 17th  to host our annual Cocoa and Cram study support for our sophomores and for our freshmen.  We encourage all students who need this additional support to attend and take advantage in preparation for a Rancho Strong finish to the semester.  
Parents, please continue to help our 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 school every day on time.  Working together, we can increase our student’s chances of success.
Take a look at the Fall Semester finals schedule below.

I know students and staff are continuing to work to the best of their ability. I am incredibly proud of the efforts from Cougar Country and I want to encourage our students to not give up, and give your best efforts to finish this first semester strong.  
Finally, I would like to extend well-wishes to our entire school community during this holiday season.  Please enjoy the winter break, and we look forward to starting second semester on Monday, January 9, 2023. Thank you again and have a great day!
