Welcome to Excelsior’s Redlands campus! 

We are excited to begin our second year at the Redlands Campus and serve the families of Redlands and all neighboring communities! 

Our primary goal at Excelsior is to prepare students to be successful adults with the support and guidance from our experienced, credentialed teachers and facilitators. Each student is assigned to a facilitator. Facilitator’s assist with connecting the student to additional educational supports throughout their campus.  All students are assigned high school A-G UC approved coursework to prepare students for admission into the university system.  Through our dual enrollment partnership with a local community college, the student may take advantage of reserved courses and guaranteed enrollment tuition free! We assist the student with the enrollment process and guide the selection of appropriate coursework. This is a great way to get a head-start in completing required general education college courses, while saving thousands on future college tuition and material fees. 

Excelsior is a parent choice school, which means parents can choose Excelsior, regardless of their place of residence. We provide each student with the necessary tools to be engaged in their learning, explore future career opportunities, and have some flexibility in their schedule. All students are given a Chromebook during their enrollment at Excelsior to access their curriculum.  We have a variety of opportunities for students to engage in their education, whether they choose to complete their schooling independently at home or attend classes on the campus. Excelsior provides extra-curricular activities and leadership opportunities to all students. These opportunities include Leadership/ASB, Yearbook/Photography, Intro to Theatre Production, Cyber Security CTE program, and other electives that are being developed this year. Students can also participate in career exploration, financial aid and college application workshops, college dual enrollment classes, health & wellness club, reward trips, student recognition award ceremonies, and clubs that will be formed based on student interest. 

Excelsior’s focus is to provide students with a positive and enriching learning experience, while allowing them to feel safe and connected to their school. We invite you give us a call for more school information or to answer any specific questions you may have regarding your child.
