For an isoscalar target, we show that the dominant QCD corrections to the ratio of the neutral- to charged-current events are suppressed by sin^4 theta_W, where theta_W is the weak mixing angle. We then discuss the implications for the NuTeV determination of sin^2 theta_W.16 pages, LatexHigh Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
