the top level of non-league football is the national league. it has a national division (national league) of 24 clubs (level 5). it is the lowest level with a single league for the whole country. this division is like the four above. it is a full-time professional competition. however, some promoted clubs keep their part-time status. there are two divisions at level 6. they cover the north (national league north) and the south (national league south). they have 22 clubs each. some of these clubs are full-time professional clubs. the other clubs are semi-professional. below the national league, some of the stronger clubs are also semi-professional. however, in the lower levels, soon all the clubs are amateur. lower-level leagues are also often for smaller regions. this is because smaller clubs don't have as much money to travel far away.
