The school year is rapidly coming to an end. With just a few weeks left of school before finals, our students are focused on finishing strongly. Final progress reports have been mailed home, and it is an important tool for our students to gauge their progress in each class.  I encourage our families to monitor School Loop and communicate with teachers and counselors if you have any concerns. 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.

May brings out our heavy hitters for the Advanced Placement Exams. Our students began working for this assessment last summer. We will be administering over 1,300 exams which is impressive! They are excited and ready! The schedule for AP Exams:

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.
