LearnBoost welcomes Glenwood Elementary
The school is located on a 33-acre (130,000 m2) campus in central San Rafael.
San Rafael High School opened in 1888. The school's current campus opened in 1924. 
The school is often cited as the origin (1975) of the time and codeword 420 in drug culture; originally "420" served as a code word for "The Waldos", a group of marijuana users who would meet in front of a statue of Louis Pasteur at 4:20 P. M. to smoke marijuana, both near the statue and at other clandestine locations on campus grounds. "420" also allegedly referred to local police code for a suspected marijuana violation. The "420" moniker was in widespread use on campus during the '74 through '76 timeframe by the school stoner community. As the usage spread, the original connotations of the word "420" faded away.
KSRH is the school's radio station, which is completely operated by students. The station broadcasts on only 10 watts of power on 88.1 FM and 107.3 Cable FM. The station takes requests during schools hours at (415) 457-KSRH.
Facilities at the school were upgraded with funds from bond measures passed in 1999 and 2002.
In 2006, the school scored 680 on the Academic Performance Index (API), the California Department of Education’s program for measuring school accountability. It also passed all Adequate Yearly Performance (AYP) criteria required by the federal No Child Left Behind (NCLB) Act of 2001.
In September, 2008, the school served as a primary location for the independent feature film, The Prankster. School was in session while filming took place and some students and teachers had background roles in the movie. The principal, Judy Colton, had a small speaking part with Kurt Fuller, who played Dean Pecarino in the film.
