The transport interaction rates of elastic scattering processes of thermal partons in the quark-gluon plasma are calculated beyond the leading logarithm approximation using the effective perturbation theory for QCD at finite temperatures developed by Braaten and Pisarski. The results for the ordinary and transport interaction rates obtained from the effective perturbation theory are compared to perturbative approximation based on an infrared cutoff by the Debye screening mass. The relevance of those interaction rates for quark-gluon plasma possibly formed in ultrarelativistic heavy ion collision is discussed.
