At the top is the Lega Nazionale Professionisti ('National Professional League', often referred to as 'Lega Calcio'), which has two divisions (Serie A and Serie B). Below that is the Lega Professionisti Serie C ('Professional Serie C League', often referred to as 'Lega semi-professionisti'), which rules Serie C1 (with two parallel divisions) and Serie C2 (with three parallel divisions). Then there is the simply named Serie D, a league of nine parallel divisions (in which the clubs are divided by geographical location) that is organised by the Comitato Interregionale ('Interregional Committee') of the Lega Nazionale Dilettanti ('National Amateur League'). Under them there are five more levels: four of them, Eccellenza, Promozione, Prima Categoria and Seconda Categoria, are organized by regional committees of the Lega Nazionale Dilettanti, the last one, Terza Categoria, by provincial committees.
