Whittier Union begins new school year
WHITTIER — More than 9,200 students returned to Whittier Union High School District campuses this month as the district began the 2026-27 school year with a new cell phone policy, artificial intelligence guidelines and leadership changes at two schools.
The first day of school was Aug. 12, following the district’s annual Day One gathering for employees on Aug. 10 and Freshman First Day on Aug. 11. Incoming ninth-graders toured campuses, met classmates and took part in performances and other orientation activities.
The new school year also marked the debut of Santa Fe High School’s new Sentinel mascot. The school selected the mascot after a months-long process prompted by a new California law prohibiting public schools from using Native American-themed mascots.
District officials said thousands of students and other stakeholders participated in surveys and informational meetings before the Sentinel was chosen.
“The Sentinel embodies the values of our community identified from the beginning — including bravery and courage — and reflects a sense of guardianship and pride, while honoring Santa Fe’s legacy of resilience and excellence,” Principal Craig Campbell said.
Whittier Union also entered the year with new administrators at two campuses. Steven Rodriguez, formerly the district’s director of business services, became principal of the United Sierra Education Center, which includes Frontier High School, Sierra Vista High School, Whittier Union Adult School and the Adult Transition Program.
At La Serna High School, Dr. Sam Sanford was named interim principal after previously serving as an assistant principal there.
Among the most significant changes for students was a new districtwide mobile device policy prohibiting cell phone use during instructional time. The policy also established guidelines for smart devices, privacy restrictions and consequences for unauthorized use.
Students remained permitted to use their phones during non-instructional periods and in emergencies.
Whittier Union also introduced a set of guidelines governing artificial intelligence. The principles emphasized human-centered, ethical and secure use of AI while supporting, rather than replacing, teachers and human interaction.
The guidelines addressed AI literacy, academic integrity, transparency, privacy, personalized learning, staff training and college and career readiness.
“The first day of school at Whittier Union is always an exciting time,” Superintendent Dr. Monica Oviedo said. “Our commitment is to make sure every student feels supported, challenged, and inspired to discover their strengths, pursue their dreams, and reach their full potential.”
