Principal's Message

Mr. Kirk
Rancho Family,
Wow! This school year is going by so fast!  I have enjoyed seeing our Cougars work hard in and out of the classroom in order to see our vision become a reality.  That vision is, “all students will graduate ready for college and careers.”  That is what drives us as a staff and that is why every one of our students are important.  
As we wrap up the third quarter, the focus shifts to gearing up for the final push of the school year with important events such as CAASPP/CAST Testing, AP Exams, prom and yes, our commencement ceremony.   
We take pride in our school and the development of our students’ achievements and school pride. This is why our teachers have been working hard to prepare our Cougars for the CAASPP/CAST and AP Exams. Both of these exams are used by our state as part of the California Dashboard which uses five state indicators in order to measure the continued progress schools throughout California. 
Our junior students will be taking the CAASPP, our senior students will be taking the California Science Test (CAST) and many of our 9th – 12th graders will be taking AP Exams.  I want to encourage you all to get plenty of rest before testing days, eat a healthy breakfast and give your best effort! I want all our Cougars to go into this testing season full of confidence in their preparation and abilities.  
Below are the dates for these exams as well as important dates to remember for the remainder of the school year.

I am proud of the hard work I have seen so far, but we are not done yet.  Let’s finish the year strong Rancho and stay on track to truly be college and career ready!  
Bleed Purple,   
Mr. Joshua Kirk
