Dear Families and Students,

It is that time of year when our students get to showcase their talents in academics. We are ready to begin our CAASPP Smarter Balance Assessments and CSTs in Life Science. CAASPP will measure our Junior Class in English, Mathematics and for the first time in Science. Our students have taken advantage of class time, PTSS Saturday School, and have also participated in full practice assessments for CAASPP. They are prepared and ready.

The dates for the Exams are:

  • March 28th- April 7th English Language Arts
  • April 10th-18th Mathematics
  • April 24th-26th NGSS Pilot Test

In May our heavy hitters are up for the Advanced Placement Exams. Our students began working for this assessment last summer. We will be administering over 1,000 exams which is amazing. They are excited and ready! The schedule for AP Exams:

  • May 1st -12th

Over the next few months our students and staff will be busy during this testing period. Rancho will continue to offer after school peer and teacher tutoring and PTSS Saturday School for added support. Our Library is also open until 3:30pm.

Rancho Cucamonga High School would also like to announce our 1st Annual Professional Career Day.  This event will take place on Friday March 31st, 2017 and will be held in our English classes.

On April 27th, Rancho Cucamonga High Schools State Award Winning Rancho Remembers, will once again host 300 Veterans. These amazing individuals will speak to our students and we will gain an understanding and appreciation of how these heroes have served our country.

Rancho has earned respect by setting high standards and on-going support to obtain maximum student achievement for every student. It is my honor to work with the tremendous students and staff that make Rancho great! Rancho is proud of its academic success and our expectations for all students are:

  • They will be empowered with knowledge
  • They will be  College and Career ready

We are proud of the fact that each year our students are accepted at some of the most prestigious colleges and universities in the nation.

I am looking forward to seeing you at our events and activities! Follow me on Twitter at @RCHS_Cougars for the latest news.  Stop by and say hello when you see me on campus.

Thank You,   


Cary Willborn
