Bilingual Extension Institute
The Bilingual Extension Institute at Teachers College Columbia University provides clinicians with the knowledge and skills to make these differential diagnoses and provide appropriate services. The bilingual extension certificate requirement of the State Education Department recognizes the need for special training. Any clinician who works with bilingual children and adolescents (ages 3-21) for IEP based-services must obtain this add-on to their Teacher of Students with Speech and Language Disabilities certificate. The Bilingual Extension Institute at Teachers College Columbia University fulfills all requirements of the bilingual extension, except for the NYSED BEA, the language proficiency test.
