Ohio teachers are retiring at their highest rate in years. 7,915 veteran teachers retired at the end of 2013 – a twelve percent increase over 2011. One of the main reasons for the uptick is that many older teachers decided to remain in their jobs through the economic uncertainty that set in with the Great Recession, and now they’re ready to make the move and retire. Discontent with the new Common Core learning standards may also be a factor. The growing retirement pool cost Ohio public schools over $60 million in replacement and recruitment expenses last year.
