Bilingual Extension Institute

Welcome to the Bilingual Extension Institute

Over the past almost 30 years, more than 800 bilingual speech-language pathologists have successfully completed the Teachers College, Columbia University Bilingual SLP Extension Institute, founded and directed by Professor Catherine Crowley. Taught by an eight-person faculty and seven master clinicians, the Institute’s Advanced Certificate in Bilingual Speech-Language Pathology is designed to provide students with the knowledge and clinical skills needed to provide culturally and linguistically appropriate services for children and adolescents. 

  • Requirements: Discipline-specific and open only to bilingual speech and language providers and speech-language providers who want to enhance their competencies and skills in working with bilingual children/adolescents
  • Academic Credit: Offered as a credit-bearing, non-degree program. Students receive six graduate-level credits from Teachers College, Columbia University through two courses focused on assessment and treatment for pre-school and school-age children. The cost is discounted from the current cost for credits at Teachers College, Columbia University.
  • CertificateBoth the online and in-person Bilingual Extension Institute offer NYSED Bilingual Extension certificate to the NYSED Teacher of Speech and Language Disabilities (TSLD) certificate and an advanced certificate in bilingual speech-language pathology. The Institute is not limited to those planning to practice in New York State. In fact, several hundred speech-language providers have completed the Institute who never intend on practicing in New York State and have received the Advanced Certificate in Bilingual Speech-Language Pathology.

The Bilingual SLP Extension Institute is still accepting applications for the on campus cohort (Fall). Total tuition for all six credits in 2023 is $6,950, or $3,475 for each of the 3-credit courses.

Both the online Institute and the in-person Institute are offered each year. Students can join the in-person Institute in the fall semester and finish the following summer. However, students can only begin the online Institute each May and finish in December.

The Bilingual SLP Extension Institute is six graduate-level credits from Teachers College, Columbia University. The program is divided into two parts, each consisting of two three-credit courses.

For holders of the New York State Education Department (NYSED) Teachers of Students with Speech and Language Disabilities (TSSLD) or Teacher of Speech and Hearing Handicapped (TSHH) certificates, the Bilingual Extension Institute fulfills all requirements of the NYSED, except for the NYSED BEA, the language proficiency test.

Students who complete the Institute meet the requirements for the Teachers College Columbia University Advanced Certificate in Bilingual SLP. Those students who also want the NYSED bilingual extension certificate must also hold the “base certificate” (the TSSLD or TSHH), pass the NYSED Bilingual Education Assessment and apply through the TC Office of Teacher Certification.
