  A real space Renormalization Group approach is presented for a non-mean field
spin-glass. This approach has been conceived in the effort to develop an
alternative method to the Renormalization Group approaches based on the replica
method. Indeed, non-perturbative effects in the latter are quite generally out
of control, in such a way that these approaches are non-predictive. On the
contrary, we show that the real space method developed in this work yields
precise predictions for the critical behavior and exponents of the model.
