The dynamic Monte Carlo renormalization group is applied to the two-dimensional Kawasaki and three-dimensional Glauber models. Our best "matching" results for the Kawasaki model yield a value of $z=3.80\mathrm{}$ for the dynamical exponent, as compared with the exact value $z=3.75\mathrm{}$. This provides strong confirmation for the validity of this method. The results for the Glauber model are less accurate, but our estimate of $z\simeq 2.08$ is in reasonable agreement with the $\epsilon$ expansion.
