The purpose of the Dual Language and English as a Second Language (ESL) Programs in Keller ISD is to enable emergent bilingual students to develop fluency in oral language, reading comprehension, and writing skills in English. The programs focus on the development of literacy and academic skills through the use of second language learning methods.

KISD's EL Programs strive to meet the educational needs of each linguistically diverse student by recognizing the affective, linguistic, and the cognitive domains to enable students' successful and equitable participation in all instructional programs.
