Jasper and Whiteout (for Engineering and Science Education Program) Ramon Magsaysay (Cubao) High School (RMCHS), also referred to by its colloquial portmanteau Monsay or Monching (as homage to one of Ramon Magsaysay's nicknames), is a public high school in Quezon City, Philippines.

Due to accelerating socio-economic development in Quezon City, Cubao High School annexes began sprouting.

The school year 1968-1969 saw a record boom in enrollment, resulting in the lack of accommodations for more than 81,000 students.

To remedy the situation, the old Quezon City Hall, standing on prime land at the corner of EDSA and Minnesota St. (now Ermin Garcia St.), was appropriated as the permanent school site.

[8] Through the initiative of former First Lady and then Metro Manila Governor Imelda Marcos and then city Mayor Adelina S. Rodriguez, construction of a P13.6 million school building began in 1982.

To cope with the demand for more classrooms, the city government vacated the adjacent Post Office to give way to the construction of a new school building sponsored by then-Congressman Sonny Belmonte in 1997.

This new building now serves as the house for computer units and laboratory equipment for the Junior High School (JHS) students, with the Mathay Building being the house for the computer units and laboratory equipment of the Senior High School (JHS) students, in response to the country's shift to the K-12 curriculum.

The following people below are the list of alumni from the school that became part of the various arts, media, and entertainment hubs in the Philippines.
