A number of other organisations, most of which are known as 'masonic' or have a title identifying themselves as masonic, require candidates for membership to be a Master Mason in "good standing" (subscriptions paid, and not under any form of discipline). In some countries, notably the United States of America, the Scottish Rite and the York Rite are the two principal routes available. In other countries, notably England, Scotland, Ireland, and many of the countries of the Commonwealth, a large number of 'stand-alone' Orders and Degrees exist, without the umbrella organisation of a "rite". Some of these masonic bodies use numbers as an informal way of referring to or identifying the degrees they confer, but the most important and therefore "highest" degree is always the third, or Degree of Master Mason. These other masonic bodies (sometimes known as 'additional degrees' or 'side degrees') are optional pursuits for those who wish to take their masonic membership and activity beyond the three degrees of Entered Apprentice, Fellowcraft and Master Mason.
