Josh Schlegel helped turn Harrison's Math scores around starting in 2009.
The school was ranked in the Washington Achievement Index's bottom 14-percent. Then leaped into the top four percent in two years.
Schlegel is happy to see he's made a difference.
"This award really means to me that the work we're doing in Sunnyside is really being impactful, really making a difference that people are noticing that the work we're doing in Sunnyside is worthwhile," Schlegel said.
Schlegel was selected by several school board members across Yakima County.
