El Camino High School is one of two high schools of the Oceanside Unified School District, located at 400 Rancho Del Oro Drive in Oceanside, California. Declared a California Distinguished School in the early 2000s, it was originally named "Oceanside High School East", and officially became El Camino High School in 1976. El Camino's Truax Theatre was built in the early 1980s and houses a large performance venue, an adjacent classroom with stage and large music and drama rooms. It also recently built a new Science and Technology Building and is undergoing constant construction to clean up the campus. El Camino maintains a close athletic rivalry with Oceanside High School. The ECHS mascot is the "Wildcat" and the school colors are brown and gold.
