The Williamsville School Board granted Superintendent Scott G. Martzloff a two-year contract extension that raises his pay by 2.7 percent.
Board members on Wednesday extended Martzloff's contract, which was set to expire in May 2020, to June 2022.
He will earn $233,296 per year while all benefits and other provisions remain the same.
Martzloff, 48, has served as superintendent of the region's largest suburban district since 2011. This is the first time Martzloff has received a raise or extension since 2015.
A district news release said Martzloff has worked to reduce class sizes, add support programs for students and win voter support for school budgets and a 2015 high school sports capital project.
Martzloff also endured bitter internal issues that roiled the district between 2014 and 2017, centered on a deep rift with the teachers' union.
