Within the English football league system, the Central Midlands League's two divisions, called the North Division and South Division, are considered part of the National League System (at Step 7), while the two reserve divisions are not. Four clubs from the previously-named Premier Division had the distinction of being the lowest-ranked clubs, and only ones outside the NLS, accepted for the 2006–07 FA Vase. For the 2008–09 season, eight of the leading sides left the Central Midlands League to join forces with eight clubs from the Leicestershire Senior League to form a new league, the East Midlands Counties League, at Step 6 of the National League System. For the 2015-16 season reserve teams of clubs who play higher up the pyramid were allowed to participate in the league for the first time.
Champions of the North Division are eligible (if they meet ground standards) for promotion to the Northern Counties East League Division One and champions of the South Division are eligible for promotion to the East Midlands Counties League, and some clubs have progressed from the CML to the National League North and Northern Premier League. A representative side from the league takes part in the FA Inter-League Cup.
Local leagues below the Central Midlands League on the pyramid are the Doncaster and District Senior League and the Midlands Regional Alliance. In most cases these have multiple divisions or feeder leagues of their own.
