Status: to appear in Mathematische Annalen Abstract: Among the cellular algebras, the quasi-hereditary ones are characterized in three different ways; by finiteness of global dimension, by the Cartan matrix having determinant one, and by the length of a given cell chain being equal to the number of simples. As an application, it is determined when a Brauer algebra or a partition algebra is quasi-hereditary.
