Without certification, people could not professionally call themselves alchemists or use their resonance without a credentialled supervisor. The guilds wanted the certification and admissions of the Alchemy Institute to remain limited, both because it increased the value of their credentials, and because those without formal certification were cheap to hire for alchemical factory work. However, the guilds also wanted assurance that their heirs would be the ones entering the Institute, no matter whose resonance or aptitude was greater.
