Chicago provides a clue as to why teacher turnover might be high and to why as the Seattle Times reports in a given year, “almost one-third of the 3.4 million K-12 teachers are moving into, between or out of schools.” The Chicago Sun Times reports that complaints about city teachers and other public school employees living illegally outside Chicago tripled during the last school year. The horror: Chicago public school teachers were caught living as far away as Plainfield, Lockport and even in posh Glencoe, according to Inspector General James Sullivan’s annual report, released Thursday. Almost all CPS employees hired after 1996 must live in the city, and this school year, principals were ordered to make sure new hires move into the city within six months of their starting date. Schools CEO Arne Duncan insists the system has been able to recruit more and better qualified teachers, despite the residency requirement. Sure. Way to be competitive and attract those high quality teachers. And good to know Chicago is targeting resources to improve the quality of education for the city’s students.
