The Ancient and Accepted Scottish Rite of Freemasonry (the Northern Masonic Jurisdiction in the United States often omits the and), commonly known as simply the Scottish Rite, is one of several Rites of the worldwide fraternity known as Freemasonry. A Rite is a series of progressive degrees that are conferred by various Masonic organizations or bodies, each of which operates under the control of its own central authority. In the Scottish Rite the central authority is called a Supreme Council.

The thirty-three degrees of the Scottish Rite are conferred by several controlling bodies. The first of these is the Craft Lodge which confers the Entered Apprentice, Fellowcraft, and Master Mason degrees. Craft lodges operate under the authority of Grand Lodges, not the Scottish Rite. Although most lodges throughout the English-speaking world do not confer the Scottish Rite versions of the first three degrees, there are a handful of lodges in New Orleans and in several other major cities that have traditionally conferred the Scottish Rite version of these degrees.

The Scottish Rite is one of the appendant bodies of Freemasonry that a Master Mason may join for further exposure to the principles of Freemasonry. In England and some other countries, while the Scottish Rite is not accorded official recognition by the Grand Lodge, there is no prohibition against a Freemason electing to join it. In the United States, however, the Scottish Rite is officially recognized by Grand Lodges as an extension of the degrees of Freemasonry. The Scottish Rite builds upon the ethical teachings and philosophy offered in the craft lodge, or Blue Lodge, through dramatic presentation of the individual degrees.

Birth of the Scottish Rite
Although most of the thirty-three degrees of the Scottish Rite existed in parts of previous degree systems, the Scottish Rite did not come into being until the formation of the Mother Supreme Council at Charleston, South Carolina, in May 1801.

Isaac De Costa, one of the deputies commissioned to establish Morin’s Rite of the Royal Secret in other countries, formed constituent bodies of the Rite in South Carolina in 1783, which eventually became, in 1801, The Supreme Council of the Ancient and Accepted Scottish Rite, Southern Jurisdiction. All regular Scottish Rite bodies today derive their heritage from this body. In either 1813 or 1867 the Ancient and Accepted Scottish Rite, Northern Masonic Jurisdiction of the United States, was formed.

Systems of Degrees
According to the various Scottish Rite jurisdictions in the world, all of which operate independently, the Scottish Rite degrees are worked at will by their governing bodies. For example, the Southern Jurisdiction separates the degrees as follows:

4° through 14°: Lodge of Perfection
15° through 18°: Chapter of Rose Croix
19° through 30°: Council of Kadosh
31° and 32°: Consistory

This is different in the Northern Jurisdiction:
4° through 14°: Lodge of Perfection
15° and 16°: Council of Princes of Jerusalem
17° and 18°: Chapter of Rose Croix
19° through 32°: Consistory

In Scotland, candidates are perfected in the 18th degree, with the preceding degrees awarded in name only. A minimum of a two-year interval is required before continuing to the 30th degree, again with the intervening degrees awarded by name only. Elevation beyond that is by invitation only, and numbers are severely restricted.

Similarly in England, the candidate is perfected in the 18th degree with the preceding degrees awarded in name only. Continuing to the 30th degree is restricted to those who have served in the chair of the Chapter. Elevation beyond the 30th degree is as in Scotland.
