A proposal at JLab, which plans to measure the parity-violating asymmetry in deep inelastic scattering with high precision over a broad kinematic range, has recently been conditionally approved. The asymmetry is sensitive to poorly-determined couplings in the standard model as well hadronic effects such as charge symmetry violation at the quark level and higher twist effects. In this article, we discuss both the physics motivation for the new experiment and a description of a the proposed apparatus.
