About SIL

We long to see people flourishing in community using the languages they value most.

Who we are:
SIL International is a faith-based nonprofit organization. Founded in 1934, SIL has grown from a small summer linguistics training program with two students to a staff of over 5,000 people from 89 countries of origin. SIL is currently involved in over 1,660 active language projects, representing 1.07 billion people in 162 countries.

What we do:

Inspired by God’s love, we advocate, build capacity, and work with local communities to apply language expertise that advances meaningful development, education, and engagement with Scripture.

Who we serve:
Our services are available without regard to religious belief, political ideology, gender, race or ethnic background.



The international headquarters for SIL is located in Dallas, Texas, USA, with additional regional administrative offices on five continents. The organization is incorporated as the Summer Institute of Linguistics, Inc. (SIL), a Texas non-profit educational corporation, and is recognized by the U.S. Internal Revenue Service as exempt from income tax under Section 501(c)3 of the U.S. Internal Revenue Code. An international Board of Directors with thirteen members from eight nations provides governance to SIL.
