  NuTeV has performed precise measurements of neutral-current to
charged-current cross section ratios using intense high energy neutrino and
anti-neutrino beams on a primarily steel target at the Fermilab Tevatron. A
null hypothesis test of the standard model allows the extraction
$\sin^2\theta_W^{\nu N}(\equiv
1-M_W^2/M_Z^2)=0.2277\pm0.0013(stat)\pm0.0009(syst)$, a value that differs from
predictions of global electroweak fits by $+3.0\sigma$.
