According to the Wake County Schools blog,
As of April 9, 2014, more than 600 teachers have left their jobs since the beginning of the school year on July 1, 2013, an increase of 41 percent over the same period last year.
Here is some perspective: According to the N.C. Department of Public Instruction, Wake County employed 10,331 teachers this year. Moreover, 1,170 teachers left their Wake County school last year, although around three hundred of those stayed in education.
At this point, Wake County school officials should examine the district and school conditions that led to the rise, unless a similar phenomenon is occurring in other school districts. If Wake is not alone, then state legislators will have to take action during the session that begins next month.
