It rates the academy on where its graduates ended up, aggregated across decades and every staff that ran it.
The most informative academy signal is the advancement record: every player who came through, and where he went after. Up, to the first team or a profitable sale, or down and out. Reputation and youth silverware do not enter it. Only the destinations do.
It is regime-independent by construction, aggregating outcomes over many years and staffs rather than one good crop. A famous academy that has stopped producing shows up immediately as players who no longer advance; an unfancied one that quietly graduates professionals reads as the developer it is. Judge the academy by the careers it produced, not the name it carries.

A first team's form changes with every manager. An academy is the constant underneath: the great ones graduate first-team players and high-fee sales decade after decade, regardless of who runs the senior side. So it is rated across regimes, and can be elite even while the first team underperforms.
The same principle that separates a club from its manager, applied to youth: the dugout is temporary, the developmental machine is not. An academy that produces through good first teams and bad ones has proven the environment does the work, not one lucky generation under one good coach. A first-team table is this season. An academy record is the institution.

The advancement record does a second job: it reveals the development environment without facility data. A weak setup suppresses players, so it shows up as an academy where they fail to advance, and no facility score is ever fabricated. The payoff: it conditions what a young player is projected to become there.
This is why the rating is not just a scorecard. When a sixteen-year-old chooses where to develop, or a club decides where to send a loanee, the academy read changes the projection, toward the ceiling at a strong one, away from it at a weak one, always inside the same hard bounds as every projection. The record grades the academy. Then the academy re-prices the kid.
Illustrative engine read on the real environment proxy (the advancement record as the emergent facility signal, never a fabricated facility score) and the development-environment feed (destination-conditioning of a young player's trajectory, bounded by the ceiling plus frame). Composite reads, demonstration figures.
The careers are the rating, and the rating is the bet on the next kid.
The Academy read grades the youth pipeline on its advancement record, reads the environment from the outcome, and conditions what a young player is projected to become there.
