In 2018, the grading system of Junior Championships was drastically changed. The Dublin Junior Football Championship is divided between Junior 1 and 2.
Junior 1 consists of 16 teams who are divided into four groups of four. The top two sides in each group are then included in an open draw for the quarter-finals of the championship. The team that wins the Dublin Junior Football Championship is promoted to the Dublin Intermediate Championship. The teams that finish at the bottom of their respective groups go on to play in a relegation championship. The eventual loser drops to the Dublin Junior Football Championship 2.
Junior 2 consists of 14 teams who are divided into two groups of three and two groups of four. The top two sides in each group are then included in an open draw for the quarter-finals of the championship. No team can be relegated from the Dublin Junior Football Championship 2. A club that has a team in the Intermediate or Senior Championship will compete in the All County Championship. The all county championship is divided in three divisions and participation will vary each year depending on each club's performance in higher graded divisions. The winner of each all county championship will progress to a higher ranking all county championship if they do not already have a side in that championship. ==Junior Football A==
