At The Windward School, we are committed to helping students with language-based learning disabilities achieve their full potential in preparation for a successful return to a mainstream educational environment. Located in White Plains, NY, and Manhattan, NY, The Windward School educates more than 1000 students on three campuses.



Windward is a coeducational, independent day school dedicated to providing a proven instructional program for children with language-based learning disabilities. The multisensory curriculum is designed for students of average to superior intelligence who can benefit from the unique educational experience provided. Through direct instruction in small class settings, a trained staff assists students to improve their language skills. Academic success, combined with opportunities for social and emotional growth within an intentionally diverse and inclusive setting, enables students to understand their learning differences, build confidence, and develop self-advocacy skills. Windward is committed to helping students achieve their full potential in preparation for a successful return to a mainstream educational environment. To meet these goals, the School provides ongoing training to its faculty based on the most current research and shares its expertise with the parent body, other educators, and the broader community.



The Windward School is nationally recognized for its development of instructional programs and best-in-class teacher professional development. In January 2020, the School launched The Windward Institute, which is dedicated to increasing childhood literacy and disrupting the status quo in education through providing professional development for The Windward School, educators, clinicians, parents/guardians, and non-Windward students; advocating for the rights of students with language-based learning disabilities; building leading-edge education-research partnerships; and expanding the reach and impact of the proven methodology of The Windward School. This is an exciting time for Windward as Head of School Jamie Williamson leads Windward into the next chapter of its nearly 100-year history.
