Welcome to Central Union High School

Dear Parents and Guardians,
The purpose of this letter is to provide information about the proactive approach Central Union High School District has taken in securing our campuses. In light the recent shooting in Parkland, it is important to communicate how we keep our school safe. The District has followed through with many precautionary steps to making sure our staff and students are safe at school. In 2015, the District acquired the services of Close Range International, Inc. to investigate and provide a Security Threat Assessment Report of all of our campuses.
The District also established a District Safety Committee and each school has a School Site Safety Team. Through these staff teams, the District held its first Safety Summit on March 3, 2017 where the entire staff of the Central Union High School District attended. The Safety Summit included a presentation from the El Centro Police Department (ECPD) on its response procedures for an active shooter incident. Also, our School Resource Officers provided staff training on our Alert, Lockdown, Inform, Counter, Evacuate (ALICE) procedures that deals with the issue of having an active shooter on school campus. The District developed an ALICE training video which helps with continuous training and practice on this very important issue. In addition, the District contracted with Catapult Emergency Management System (Catapult EMS) to provide an emergency communication service that is accessible through handheld devices, computers, and tablets. With this service, all District administration, school site safety teams, staff, and School Resource Officers are able to quickly communicate in real time any possible threat and the level of emergency at any of our school sites.
In light of the recent acts of violence that have occurred in high schools across the nation, there have been several calls for students to participate in walk outs to ensure their voices heard. The Central Union High School District (CUHSD) supports the rights of students to express themselves on campus through organized activities. In fact, a few teachers have volunteered to teach students how to be activists for change in a positive manner, following in the footsteps of the students of MSDHS in Parkland, Florida. This ensures that the orderly operation of the school is not disrupted and the safety of our students is not threatened. However, leaving school campus during school hours to participate in a walk out and attend an off- site demonstration puts the students outside the safety zone of the school and jeopardizes the safety of our students and staff members. Therefore, the CUHSD does not support or endorse any calls for walk outs that involve going off campus during school hours and we strongly discourage students from participating in unauthorized protests. To ensure that our students’ voices are heard while maintaining order on school grounds, we have authorized the following student-led activities:
Wednesday: Student led Activities in Quad during Advisory
Should you wish to discuss this or other issues, please call me at (760) 336-4310 and we will arrange an appointment.
Craig Lyon, Principal

As the Principal of Central Union High School, I am looking forward to another great year.  It is an honor to work with over 1900 students and nearly 160 staff members to ensure a positive and rewarding experience for your student. Central Union High School is proud of our rich history of academic, extra-curricular, and athletic programs designed to benefit and advance student curricular and extracurricular achievements.  We offer a variety of course offerings and pathways that are rigorous and supported by wonderful staff members working to ensure students’ academic success.  Additionally, our students have the opportunity to participate in a variety of extracurricular and co-curricular activities that allow our students to showcase their talents throughout the year from athletic teams, Robotics Team,  cheerleading, tall flags, majorettes, Spar-teens and The Great Spartan Band to just name a few. 

This year (and every year), the students and staff of Central Union will work towards shaping the future of our students by developing skills, abilities, and knowledge. The Central Union staff believes that teaching above and beyond the standards helps ensure all students are Career and College Ready. Central Union is very proud of our rich traditions and we look forward to providing a safe and positive learning environment for all students. Help us encourage your students to become involved in our programs outside of the regular school day. Student organizations, clubs, and athletics all promote and support school community involvement and academic success.

I look forward to working with the many families that trust the Central Union staff to educate and care for their students. The administration team is always available to meet and discuss school issues or the individual progress of any student with parents, guardians, and the students themselves. Additionally, our excellent counselors and other support staff make themselves available at all times to assist in supporting our students’ experience.

To make the school year the best for you and your student please support Central Union High School in any way you can. Consider becoming part of the Spartan family, by joining the Spartan Athletic Club, our Band Booster club, or volunteering for help with school events and activities. I look forward to making the high school experience a positive and memorable one for you and your student.
