Five groups have filed letters of intent to open new charter schools in New Orleans under the auspices of the Orleans Parish School Board. Nola.com says that if the schools are allowed to open, each group will be responsible for finding its own building. New Orleans has almost 90 public schools. Most are run by the state Recovery School District. Under the Orleans Parish School Board, Encore Academy opened last fall, and two new charters are opening later this year: Homer A. Plessy and Bricolage Academy. That will bring the Orleans Parish School Board's total to 14 charter and five direct-run schools.
