Rhythms of the Village charter school got a five page letter from Pasadena Unified School District, scolding them for underenrollment, lack of textbooks, and holding naptime during classtime.  The school must also provide financial records and a financial recover plan.  Rhythms exec director Onochie Chukwurah says he can refute the letter point-by-point and will provide all the documents by next week. Rhythms of the Vilage shares a campus at the old Edison school with another troubled charter school, Nia Educational Charter School.  PSN has everthing.
