School Notes
- School Mascot: The Bearcats
- San Mateo High School is an American public high school in San Mateo, California serving grades 9-12 as part of the San Mateo Union High School District.
- History: San Mateo High School has been recognized throughout its history for its academic achievement and the role it plays in the local community. In 1991, it was honored as a National Blue Ribbon School by the United States Department of Education. In 2005, the California Business for Education Excellence (CBEE) organization bestowed a "Gold Standard Award for Academic Excellence" upon San Mateo High School.
- Legend has it that the bearcat mascot was the result of a disagreement about whether architectural adornments at the front entrance of the original building were bears or cats. During a 50-year celebration in 1977, the architect was asked to offer a definitive answer. His response: "They're owls."
- The school's traditional arch-rival is Burlingame High School.
- Campus: San Mateo High School opened in 1902 at a cottage on Ellsworth Street in San Mateo. The school moved twice in 1903 and to Baldwin Avenue in 1911 before moving to its present location in 1927. The original brick-dominated complex was sometimes referred to as "the high school that looks like a university."
- In 2001, the school undertook to demolish and entirely replace the original building in an effort to meet modern earthquake safety requirements. The new building was modeled after Hampton Court Palace in England. Dedicated in August 2005, the new building strongly echoes the design and materials of the original in part due to strong public outcry about the decision to demolish the structure. On February 10, 2006 the campus Quad was dedicated to alumnus Merv Griffin, who donated $250,000 to the school ($100,000 of which went to the performing arts department).
