Bilingual Extension Institute

Welcome to the Bilingual SLP Extension Institute

Over the past almost 30 years, more than 1000 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 its eight-person faculty,  the Institute’s Advanced Certificate Diploma in Bilingual Speech-Language Pathology is designed to provide students with the knowledge and clinical skills needed to provide culturally and linguistically appropriate services, focused on current evidence-based practice. Each student is assigned a master clinician/mentor to provide support and guidance as students integrate what they are learning into their clinical practice. 

  • Requirements: The institute is only open to SLPs 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, noted below, is significantly discounted from the current cost for credits at Teachers College, Columbia University.
  • Certificate: Completion of either the online or in-person Bilingual Extension Institute meets the requirements of the Advanced Certificate diploma in bilingual SLP. Additionally, the Institute meets the academic and clinical requirements for the bilingual extension to the NYSED TSSLD, except for passing the NYSED language proficiency test.  
    Throughout the entire almost 30 years of the Institute, many SLPs have taken the Institute who live across the country. Since the online Institute began in 2017, we have welcomed international students from Europe, Asia, and Latin America. 

The Bilingual SLP Extension Institute is accepting applications. Total tuition for all six credits in 2023 is $6,950, or $3,475 for each of the 3-credit courses, , with a course fee of $40 per semester for evaluation materials and a required Columbia Health and Related Services Fee.

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 Extension Institute 2023 and 2024

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.
