The principal at P.S. 375 in Crown Heights won't be the school's leader anymore. Many parents, students and teachers are upset that Michael Johnson was removed from the position Monday. They say he's helped turn the school around, however, the Department of Education says Johnson failed a required evaluation. Johnson was the fifth principal to work at P.S. 375 since the school opened in 2001. He will be supervising a region suspension site beginning Wednesday.
