Abstract
Results of applying analytic perturbation theory (APT) to the Bjorken sum rule are presented. We study the third-order QCD correction within the analytic approach and investigate its renormalization scheme depe ndence. We demonstrate that, in the framework of the method, theoretic al predictions of the Bjorken sum rule are, practically, scheme indepe ndent for the entire interval of momentum transfer.
