The Institute for Sierra Leonean Languages (TISLL) has been promoting the teaching of indigenous languages to religious institutions, schools, and communities since 1974. Literacy rates in Sierra Leone increased due to the classes offered by TISLL.

There is a continuing desire to gain literacy skills by a growing number of people who want to read Scripture in their own languages. TISLL is challenged to provide technical and professional services in support of the many churches and multiple language programs serving these communities. Adequate funding will allow TISLL to increase the reach and impact of literacy programs. People will grow in their faith as they gain skills to read God’s Word in a language they understand.
