You should get out of education. That was the advice first-year teacher Bill Henderson received when he discovered he was gradually losing his vision. Instead, Henderson persevered and became principal of the O"Hearn Elementary School in Boston, an ethnically and economically diverse school where about a third of the students have mild, moderate, or significant disabilities. In The Blind Advantage, Henderson describes how the journey into blindness helped him develop key qualities determination, vision, sensitivity, organization, collaboration, and humor that made him a more effective principal. At the same time, he shows how the inclusionary policies and practices at the O"Hearn School (now renamed the William W. Henderson Inclusion Elementary School), elicited and developed these qualities in others. The Blind Advantage provides insight into the challenges, possibilities, and practicalities of including students with disabilities and into the mind and heart of an inspired and determined leader.
