Rizal High School (abbreviated as RHS), an institution of secondary education based in Pasig City, Metro Manila, Philippines, has been listed as the “largest secondary school in the world” since 1993 by the Guinness Book of World Records. This evaluation is based on the size of the student population. The school was named after the Philippine national hero, Dr. Jose P. Rizal. Notable graduates of the institution include former Senate presidents Neptali Gonzales and Senator Jovito Salonga, former Senator Rene Saguisag, Maestro Lucio San Pedro, and National Artist Carlos “Botong” Francisco to mention a few. In the school year 2000-2001, Rizal High School reported a student population of 15,959. This figure stands in contrast to the institution's enrollment of 28 students at the time it opened on October 1, 1902, during the incumbency of Governor Ambrocio Flores. Students came from five towns, including the Pasig proper. Then, intermediate classes were under the supervision and administration of the secondary school principal. Dr. Josephine M. Cruz, previously a Rizal High School teacher, is the school’s current and youngest Principal. The school celebrated its centennial in 2002.
