We explore effective approaches to teaching and learning that we share with families and professionals throughout the country.
We believe that the development of the whole child is essential and that each child has unique interests, needs, and abilities.
We believe that all children who are deaf or hard of hearing can learn, achieve, and be responsible for their education.
We believe that a student's positive sense of self is critical for school achievement and success throughout life.
