The Christian Language Study Center (CLSC), formerly called the Interchurch Language School (ILS), is an ecumenical institution catering to the language needs of a wide variety of students.

It opened its doors on August 1, 1961 with the expressed purpose of teaching the major Philippine languages to missionaries. Soon, however, it also opened its doors to non-missionaries including businessmen, embassy personnel, students, etc.

In 1972 English became part of the curriculum.

In 1981, the School was incorporated as a non-stock, non-profit corporation and was registered with the Securities and Exchange Commission (SEC), the Bureau of Internal Revenue (BIR), and the Department of Trade and Industry (DTI). It is likewise accredited with the Bureau of Immigration for student visa application and extension.

Students come from all over the globe with the majority coming from Asia.


Overseeing the Center is a Board of Trustees whose members are chosen in the Corporation's annual meeting. The Board of Trustees are composed by five (5) representatives from the institutional members and four (4) elected members. The Institutional Members are: Far East Broadcasting Company, Inc. (FEBC); Lutheran Church of the Philippines (LCP); Translator Association of the Philippines (TAP); United Church of Christ of the Philippines (UCCP) and the United Methodist Church (UMC).
