PSN reports today that Nia Educational Charter School has until Friday to present a recovery plan to PUSD, which claims that the school at the Edison Elementary building, 119 W. Palm, is on the edge of bankruptcy.  A story by reporter Cortney Fielding says that Nia ended the last school year $41,999 in the red, and presently owes the district approximately $29,000 in lease payments, grounds maintenance, and food service fees.  There are also disputes over the number of students who actually attend the charter school and lagging accreditation issues.  The Edison building is also the location of another troubled charter school, Rhythms of the Village.
