After the regular season is complete, teams placed 6th-last through to 3rd-last in each division play a double-leg series (6th-last vs 3rd-last, 5th-last vs 4th-last) where the winners remain in Serie D the following season and the two losers are also relegated to Eccellenza for a total of 4 relegations in each division, 36 in total for the league.
The nine division winners enter a tournament to determine the over-all Serie D champion and is awarded the Scudetto Dilettanti.
Sporting Lucchese & Massese, both of whom played in 2007–08 Serie C1, were both placed in Girone E. The schedule in those 3 divisions needed to be expanded to accommodate these extra teams.
On March 29, 2009 Siracusa became the first team to get promoted from Serie D in the season, winning the Girone I in advance of six weeks after a 2–0 home win to Rosarno that mathematically guaranteed a spot in the 2009–10 Lega Pro Seconda Divisione for the Sicilian side.
[2] On April 26, Brindisi also obtained promotion to the fourth tier, after winning the Girone H in advance of three weeks.
