Reberger, currently a freshman at the Rose-Hulman Institute of Technology, was recently bestowed the honor by the 2010 Popcorn Festival of Clay County.
She will serve in various capacities throughout the festival, scheduled for Oct. 1-3, at Forest Park. The carnival is scheduled to begin Sept. 30.
Reberger earned the position after winning the 2010 Popcorn Festival Scholarship, valued at $500.
"I found out at (Northview High School's) senior awards night," Reberger said.
Reberger said she saw applications for the scholarship in school and elected to fill one out.
The scholarship is one of eight Reberger earned, including the Indiana Dairy Farmer's Scholarship, the James Buell Jr. Leadership Scholarship, The Tri Kappa Scholarship, the Greenwell Scholarship, the Margaret Oldham Scholarship (through the Presbyterian Church), the Rotary Club of Brazil Scholarship, and a Community Foundation Scholarship.
"They definitely added up to help," Reberger said.
Reberger plans to study biomedical engineering at RHIT.
"I've always liked science and things," she said. "And I've always had an interest in animals."
In order to win the scholarship, Reberger had to write an essay on community volunteering in addition to index all volunteer projects she has undertaken.
"This is the first time we've done the scholarship," Popcorn Festival of Clay County President Evelyn Brown said. "We've always felt it would be more fair for males and females to do the scholarship rather than the pageant."
In the past, the festival had a queen pageant. However, last year, they deleted the pageant from the festivities and began setting up rules for the scholarship program.
"It seemed like we weren't being fair to the guys," Brown said.
Brown said three people judged the essays this year. However, in the future, the Orville Redenbacher family has agreed to judge the scholarship contest.
"What we really want to do is get our community involved in (volunteering)," Brown said. "From that age group, what do they see that could make our community a better place to live? We need input from our youth."
Brown said Reberger is excited about her ambassador duties.
"She'll probably pop popcorn and talk to kids," Brown said. "She will be an excellent icon for the youth in our community."
"It will be different in the sense that I'll be more involved with the entire festival," Reberger said. "That will be pretty exciting."
In addition, Reberger said she's looking forward to the popcorn eating contest, something she has never competed in.
"I think I'll compete this year," she said.
