Some of the most consequential changes in the rankings are driven by Businessweek's employer survey which accounts for 35% of the methodology. William & Mary's business school dropped 37 places year-over-year, while North Carolina State's employer rank plunged by 35 positions. Those disappointing results caused both schools to go into free falls in the overall ranking, with NC State losing 40 places to rank 69th and William & Mary dropping14 spots to rank 51st.
