The conference was first established in 1928, with three divisions: Royal, Diamond, and Classic. A fourth division, Liberty, was added in 2018 to close the student disparity gap and create better competition in each division. The new division applies to all sports except Winter Track, Wrestling, Swimming, and Girls Cross-Country.
Timber Creek Regional High School announced in 2018 that they would leave the Olympic Conference and join the Tri-County Conference for the 2020–21 school year, which would have the benefit of having all three schools in the Black Horse Pike District competing in the same athletic conference.[1]
Gloucester City Junior-Senior High School, one of the schools that had been part of the conference since its inception, left the Tri-County Conference for the Colonial Conference. The school was replaced by Overbrook High School, which returned to the Tri-County Conference after being a member of the Colonial Conference from 2008 to 2020.[2]

"Gloucester High School is leaving the Tri-County Conference after nearly a century in the organization. Gloucester, a founding member of the TCC in 1928, has been accepted into the Colonial Conference, taking the place of Overbrook, which is moving back to the TCC after leaving in 2008.... The move wasn’t supposed to occur until 2021, but because Overbrook and Gloucester are essentially switching places, both conferences agreed it made more sense to expedite the process."
