Crowley's own published writing on the A A's grade structure, discussed in the scholarly literature on his life and organizations, frames Adeptus Minor as a major turning point in the order's ten grade sequence, a characterization documented in the order's own periodical, The Equinox, rather than asserted independently here.
General accounts of the A A note the grade's direct correspondence, in name and Tree of Life number, to the Golden Dawn's own Adeptus Minor, a continuity the order's founders, former Golden Dawn members themselves, carried forward deliberately when they organized the A A's structure in the early twentieth century.
Because the A A published its grade requirements openly, general scholarship on the order treats Adeptus Minor's threshold status as public, documented information, distinct from the specific practices a candidate at that grade is expected to undertake, which the order's published material describes only in general terms.
That the grade shares its number and name with the Golden Dawn's own Adeptus Minor, rather than being renamed or renumbered, is treated in the secondary literature as evidence of how directly Crowley carried the older order's Tree of Life correspondence into his own published system.
