The Atlantic Coast Conference voted Thursday to invite Florida State to join the eight-team league.
Officials said the details of membership will be communicated to Florida State over the next few days, but no deadline has been set for a decision by the school.
"Our conference has deliberated at length about expansion," ACC Commissioner Gene Corrigan said. "The process has been comprehensive and thorough. We feel comfortable this decision is in the best interests of the member institutions of the ACC."
Corrigan said Florida State had been an attractive candidate from the outset. "The more we learned about the institution, the more we felt they were a natural fit," he said. "Their academic and athletic programs are nationally recognized, and their addition would be a plus to our conference in every way. It would allow us to continue in a leadership position in intercollegiate athletics."
ACC members are Maryland, Virginia, North Carolina, Duke, Wake Forest, North Carolina State, Clemson and Georgia Tech.
