Dr. John Calton was principal for the 2000-01 school year, and after he resigned, Dr. Linda Miller was principal for a year. In 2002, Willie Dickerson was appointed principal served in the role for nearly 20 years until being promoted to a district-level administrative position. A new two-story Franklin High School was built between 2004 and 2006 on the site of the previous building. The construction cost $21 million. A ribbon-cutting ceremony and open house was held Jan. 22, 2006. Franklin celebrated its 100th anniversary throughout the 2009–2010 school year including at its annual Homecoming festivities in October and at a special video presentation in April. In 2016, WCS began to develop a campus master plan for FHS including improved athletic facilities, a new access road for better vehicle circulation, and expanded classroom facilities, primarily through the acquisition of the former Columbia State Community College Franklin campus, which is located next to the high school.

The annex contains 16 traditional classrooms, in addition to science labs, administrative space, and a commons area. The new space can accommodate approximately 500 students.

Although Franklin kept its mascot as the Rebels until 2020, through the 2010’s, the original cartoon of a confederate rebel was slowly phased out of school branding and school apparel. A big white "F" called the "Power F" encompassed by a maroon circle used to symbolize Franklin High School began to replace the cartoon during this time. In July 2020, during the first week of principal Shane Pantall's tenure, a committee was formed to explore whether the school's mascot should be
