  The NuTeV experiment has measured sin^2Theta_W = 0.2277 +/- 0.0013(stat) +/-
0.0009(syst), approximately 3 standard deviations above the standard model
prediction. This discrepancy has motivated speculation that the NuTeV result
may be affected significantly by neglected experimental or theoretical effects.
We examine the case for a number of proposed explanations.
