James Vaznis:

School Superintendent Carol R. Johnson will tap a charter school management organization to run one of the district’s low-achieving middle schools, a first for the state, under a plan she will present tonight to the Boston School Committee.
Johnson has not decided which middle school would be overseen by Unlocking Potential Inc., a new Boston nonprofit management organization founded by a former charter school principal.
A key part of the proposal calls for converting the middle school into an in-district charter school, which would enable the management organization to operate under greater freedom from the teacher union’s contract as it overhauls programs, dismisses teachers, and makes other changes.
