The Lexington School, founded in 1865, is the largest school for deaf students in New York State. It educates deaf children from ages 0-21. It is unique among schools for the deaf in its use of an innovative teaching model called "mediated learning experience (MLE).” MLE stresses the importance of the adult "mediator” in the child’s learning and provides teacher and parent training based on this theoretical framework. Scores on standardized tests attained by Lexington students attest to the effectiveness of MLE in improving the educational attainment of deaf students.
Lexington students come from all over the five boroughs, and a number of students have other disabilities in addition to deafness, including mobility and mental impairments. Lexington prepares all students to continue on to college, vocational education, job training, or a placement that will support them to live a responsible, productive life.
