We first define the notion of good filtration dimension and Weyl filtration dimension in a quasi-hereditary algebra. We calculate these dimensions explicitly for all irreducible modules in SL and SL . We use these to show that the global 2 3 dimension of a Schur algebra for GL and GL is twice the go
