Irmo Little League's divisions are designed so that players of similar age, grade, and skills play together, aiding in their development as ball players. As players advance through the divisions, additional skills are developed and play becomes more challenging and competitive. See Little League League Age Chart for age specific requirements for each division.

Any player who registers for Juniors and then is selected to a school ball team will automatically be moved into the Senior Division for play after their school season ends. School players are NOT allowed to play in the Junior Division. Players are to notify the league if they are selected to the school team so that they do not take a roster space away from another player.

Based on cumulative skill levels, developmental divisions with more than 8 teams may be further sub-divided.
Player placement will depend on a combination of participation levels and evaluations - there is no guarantee into which division a player will be drafted. See the League Age Chart for age specific requirements for each division.
