The Mississippi Department of Corrections wants to hire 105 more correctional officers by the end of the year.
Prison officials say they have to keep hiring because the state prison system is growing and because officers quit or retire.
The system currently has about 1,700 officers. The state started training classes recently for 100 candidates, split between the Mississippi State Penitentiary at Parchman, the South Mississippi Correctional Institution at Leakesville and the Central Mississippi Correctional Facility near Pearl.
Starting officers make $22,000 a year. They must be at least 18 years old, have a high school diploma or GED diploma, have no felony convictions and have a driver's license.
Mississippi is the second in the nation behind Louisiana in the number of people per capita incarcerated.
