In this talk I summarize published work on a systematic operator analysis for fermion masses in a class of effective supersymmetric SO(10) GUTs\citeadhrs~\footnoteThis work is in collaboration with G. Anderson, S. Dimopoulos, L.J. Hall, and G. Starkman.. Given a minimal set of four operators at MG, we have just 6 parameters in the fermion mass matrices. We thus make 8 predictions for the 14 low energy observables (9 quark and charged lepton masses, 4 quark mixing angles and tan β). Several models, i.e. particular sets of dominant operators, are in quantitative agreement with the low energy data. In the second half of the talk I discuss the necessary ingredients for an SO(10) GUT valid below the Planck (or string) scale which reproduces one of our models. \footnoteThese are preliminary results of work in progress with Lawrence Hall. This complete GUT should still be interpreted as an effective field theory, i.e. perhaps the low energy limit of a string theory.
