To help alleviate the classroom teacher shortage problem in Illinois, a law that allows retired TRS members to teach for a full school year in districts declared to be subject shortage areas has been extended until 2021. Under the law, which was set to expire in 2019, retired teachers who go back to these designated districts are not subject to “return-to-work” restrictions imposed on other retirees. The regional superintendent must designate the employment to be in a subject shortage area in order for a retiree to be able to return to work without limitation.
