It’s been five months since a parent complained to the state about teachers at a Milwaukee charter school not being licensed, and the problem is persisting.  Television station W-I-T-I reports there are 23 unlicensed teachers at Milwaukee College Prep, which is a charter school with four campuses in the Milwaukee Public Schools system.  The Wisconsin Department of Public Institution notes the charter school has high attendance, low dropout rates and improving test scores.  Milwaukee College Prep has over 130 teachers, program aides and paraprofessionals.
