The Early Childhood Development Center (ECDC) is an elementary school serving students age three through the fifth grade that is operated jointly by the Corpus Christi Independent School District (CCISD) and Texas A&M University-Corpus Christi. Located on the university campus, the ECDC is the only CCISD school that presents its entire curriculum via dual language instruction. Half of instructional time is in English and half is in Spanish. Students are admitted to the ECDC by application. Applicants are selected so that the student body represent the region's socioeconomic and language demographics. The ECDC works in close partnership with the College of Education. The university benefits by using the site for research, educator training, and programming. The ECDC benefits from the university's facilities, innovative programming, and proximity to a diverse variety of educators and ideas.
