Wake County Public School System (WCPSS) Professional Learning Teams (PLTs) survey responses have been positive over time, reaching a high plateau for the last three years. Analyses of High Five PLT Survey data from 2007-12 show that in 2011-12, high percentages (87.2%) of WCPSS teachers responding to the High Five PLT Survey provided positive responses to the items. Responses were positive from 2007-08 to 2011-12, with small increases over time. Overall, WCPSS has shown an improvement in its PLT Performance Index of 5.7 percentage points over five years. The elementary, middle, and high schools showed gains of 4.2, 7.5, and 9.1 percentage points, respectively. The implementation of dedicated time for PLT work (Wake Wednesdays) correlated to slight increases in PLT indices at the elementary and middle school levels; only the elementary level saw a slight decline when dedicated time was no longer provided.
