The Department of Corrections seeks certiorari review of a circuit court order directing it to award respondent gain time. As this court has recognized, the sentencing court lacks authority to award gain time to state prisoners, as this is a matter within the exclusive province of the Department of Corrections. See Fla. Dep’t of Corr. v. Martinez, 873 So.2d 537 (Fla. 4th DCA 2004); Crosby v. Harvey, 861 So.2d 102, 102 (Fla. 4th DCA 2003).

Therefore, we grant the petition for writ of certiorari and quash the circuit court’s order.
