Rep. Carl Rogers, R-Gainesville, has been appointed chairman of Higher Education Committee.
"It's a huge responsibility but it's a positive change," Rogers said.
He said he applied for the chairmanship following the December resignation of the previous chairman, Rep. Len Walker.
Other changes for Rogers include removal from the Transportation Committee.
Rep. Doug Collins, R-Gainesville, is no longer secretary of the Appropriations committee but remains a member.
He agreed to the change given his role as the governor's floor leader and his candidacy to represent the newly drawn 9th District in the U.S. House, he said.
He also has been appointed to the Public Safety and Homeland Security and Defense and Veterans Affairs committees.
Rep. Tommy Benton, R-Jefferson, will serve as chairman of the Human Relations and Aging Committee.

"As a freshman representative, I look forward to learning from the chairmen and other members of these committees," Dunahoo said in a news release. "I also believe that these assignments are very beneficial for the people of Hall County, who will continue to have a leader in the banks and banking committee and a voice for our parks and outdoors."
Dunahoo represents District 25, which covers South Hall.
Newly elected Rep. Terry Rogers, R-Clarkesville, has been appointed to the Defense and Veterans Affairs, Economic Development and Tourism and Human Relations and Aging committees.
