Educator Linda Nathan will discuss and sign copies of her new book, The Hardest Questions Aren’t on the Test: Lessons from an Innovative Urban School.  Nathan is the founding headmaster of the Boston Arts Academy, the city’s first and only public high school for the visual and performing arts.  Under her leadership, the school has won state, national, and international recognition, for BAA sends well over 90 percent of its graduates to college.  Nathan will share her vision of what is possible to do in urban public schools.
