What are the degrees offered in the Scottish Rite? Are there logical groupings of certain degrees?

The system comprises thirty-three degrees, arranged into administrative bodies and symbolic divisions 1.

Administratively, the degrees are organized into six governing sections 1: 1. Symbolic Lodge (1°–3°): Entered Apprentice, Fellow Craft, Master Mason 1. 2. Lodge of Perfection (4°–14°): Secret Master, Perfect Master, Intimate Secretary, Provost and Judge, Intendant of the Building, Elu of the Nine, Illustrious Elect of the Fifteen, Sublime Knight Elect of the Twelve, Grand Master Architect, Knight of the Ninth Arch, and Grand Elect, Perfect and Sublime Mason 1. 3. Chapter of Rose Croix (15°–18°): Knight of the East, Prince of Jerusalem, Knight of the East and West, and Prince Rose Croix 1. 4. Council of Kadosh (19°–30°): Grand Pontiff, Grand Master of Symbolic Lodges, Noachite or Prussian Knight, Knight of the Royal Ax, Chief of the Tabernacle, Prince of the Tabernacle, Knight of the Brazen Serpent, Prince of Mercy, Knight Commander of the Temple, Knight of the Sun, Grand Scottish Knight of Saint Andrew, and Knight Kadosh 1. 5. Consistory (31°–32°): Inspector Inquisitor Commander and Sublime Prince of the Royal Secret 1. 6. Supreme Council (33°): Sovereign Grand Inspector-General 1.

Variations exist across jurisdictions; in the Northern Masonic Jurisdiction of the United States, the Consistory begins at the nineteenth degree, and a Council of Princes of Jerusalem governs the fifteenth and sixteenth degrees 1.

Symbolically, Albert Pike classifies the system into five divisions corresponding to architectural orders: Tuscan (1°–3°), Doric (4°–14°), Ionic (15°–16°), Corinthian (17°–18°), and Composite (19°–32°) 2. Albert C. Mackey characterizes degrees nineteen through thirty-two as Philosophic Degrees because they focus on pure theosophy rather than Temple symbolism, while describing the seventeenth and eighteenth as Apocalyptic Degrees 1.
