Thornton has been at Mountain View since 2009 and with Putnam County Schools since 2004.
"If you want to see a clean school, go to Mountain View," Hatfield said.
Anita Robinson was recognized as the county's elementary teacher of the year for her work with orthopedically impaired students, and Cindy Wandling of the county's alternative program was recognized as high school teacher of the year.
The board also recognized two teachers with 40 years of service: Adele Groom of Hurricane High School and Dovetta Harless of Lakeside Elementary School.
Hatfield also told the board that the state has recognized 10 schools in Putnam County as Exemplary for 2012-2013.
Confidence Elementary, Eastbrook Elementary, Hurricane Town Elementary, Mountain View Elementary, Poca Elementary, Scott Teays Elementary, West Teays Elementary, Poca Middle, Hurricane High and Winfield High schools all earned exemplary status.
Exemplary status is a state-level recognition for schools that meet requirements such as standardized test scores and graduation rates. In total 58 schools in the state earned the honor, and Hatfield told the board he believed Putnam had the most schools of any county.
Also at Monday's meeting, the board heard from Judy Grumbling and her therapy dog, Boo Boo, about a program to encourage young readers.
Grumbling's therapy dog is trained to listen to children read aloud to help them gain confidence as readers. She told the board more than 400 students have graduated to the next reading level after working with Boo Boo and that she wants to bring the program to Putnam County.The Putnam County Board of Education meets at 7 p.m. the first and third Monday of each month at the school district's central office in Winfield. The next meeting will be Nov. 5. All meetings are open to the public.
