Hamm was chosen from 130 nominations honoring nurses in southwest Missouri for their efforts.
Hamm was nominated by one of her fellow teachers at Monett Elementary School.
Portions of the nomination letter follow:
"[Hamm] is one of the most caring individuals I have ever met. She goes above and beyond the call of duty every day, and she always does things with joy and love. She also does amazing things for our children, like bringing a diabetic boy to school every day so he can eat a school breakfast and not get sick on the bus. She works behind the scene in our backpack program to help students who don't have enough to eat at home. She collects clothes for students who come to school with inadequate clothes, as well as the dreaded head checks and changing of soiled clothes. She has students who come in every day just to give her a hug.
"Carole always has a truly genuine smile on her face. She makes every teacher and student feel welcome. I have never seen a frown or heard her say one negative word. Nurse Hamm's caring and compassion is why I am nominating her for School Nurse of the Year."
Hamm was honored at the elementary school on Tuesday with a celebration that included cake and cookies for staffers and students.
"I'm not used to being the center of attention," Hamm said, "but I am going to bask in this."
