Principal's Message

Larry Rook, Principal
Dear Jaguar Family,
Welcome to the 2020-2021 school year! I am so proud and humbled to be the new Principal of Ontario High School. Coming into this new school year we have all unfortunately experienced times of uncertainty, but we must all stay optimistic. I am excited to have the opportunity to safely come together once again and kick off the new school year! The first days of school are always filled with excitement and anticipation, although this year will be like nothing we could have imagined. With COVID-19 challenges and a new Hybrid Instructional model/schedule the Ontario High School staff is committed to maintaining a safe and orderly environment, delivering quality instruction, and continuing to provide students with opportunities to be involved on campus. As we prepare for the upcoming year, our school and district will be implementing safety procedures that will require all students and staff to participate in a daily wellness check before entering our campus which includes the checking of each person’s temperature, two health screening questions and the wearing of masks. Social distancing guidelines will be practiced and multiple hand sanitizer dispensers, portable hand washing stations, and well-stocked restrooms will be available to ensure proper personal hygiene for students and staff members throughout the day. 
This Hybrid Instructional Model/Schedule will allow half of the student population to attend on their designated day, with a maximum of 18 students in a traditional class at a time. When students are not physically in class, they will utilize the Canvas Learning Management System ( as a hub for their learning and communication - safely from home. The school year will begin on Wednesday, August 5, 2020. If a student or parent is not comfortable returning to school on this schedule, they will have the option to continue with distance learning if they meet State/District (AB77) requirements. It is critical that all Ontario families complete the following Google form regarding their preferred learning model as soon as possible so your student will be placed in the correct schedule. 
To maintain the safety of students, their families, and our OHS staff, our Spirit Day schedule pick-up procedures for the upcoming 20-21 school year have changed. Students will be required to wear face coverings and maintain social distancing while attending our summer Spirit Days. In order to minimize the number of people on campus, we are asking that only one parent/guardian (if needed wearing a mask) accompany the student attending on their designated schedule pick-up day. 
Spirit Days will be July 27 to July 31 from 8am to 2pm.  To allow for social distancing, we will have one grade per-day for 6 hours each day. 
Monday, July 27 - Seniors
Tuesday, July 28 - Juniors
Wednesday, July 19 - Sophomores
All grades Except Freshmen will follow the below alpha breakdown for times to come on campus: 
8am to 9am - A - CA 11am to 12pm - ME - PA
9am to 10am - CE - GO 12pm to 1pm - PE - SA

Please note that the safety of our students and staff is of the utmost importance and this information may change based on the advisement of county health officials.
Ontario Jaguar families, I am excited and look forward to the 2020-21 school year. I truly believe that we are stronger together, and we will overcome and not allow barriers to stand in our way. We are here to support you, encourage you, and push you to great heights. We will work to provide you with the best experience that we can this school year, even with the challenges that lie ahead I am excited to begin the year with you.
