Abstract: We generalize Bray's self-consistent screening approximation to describe the critical dynamics of the theory. In order to obtain the dynamical exponent z, we have to make an ansatz for the form of the scaling functions, which fortunately can be restricted by general arguments. Numerical values of z for d = 3, and n = 1, ..., 10 are obtained using two different ansatz, and differ by a very small amount. In particular, the value of obtained for the three-dimensional Ising model agrees well with recent Monte Carlo simulations.
