Precision measurements of electroweak observables at Q{sup 2}<<M{sub Z}{sup 2} complement high energy collider experiments in order to comprehensively search for new dynamics at the TeV scale. Parity-violating electron scattering is one promising technique that has demonstrated the potential to achieve sufficient precision, and which has unique sensitivity to TeV scale dynamics. In particular, we discuss parity-violating electron-electron (Moeller scattering). After reviewing the completed SLAC E158 experiment, we discuss a new project to improve on the SLAC measurement by a factor of 5 using the upgraded 12 GeV beam at Jefferson Laboratory, allowing a measurement of the weak mixing angle sin {sup 2}{theta}{sub W} with comparable precision to the single best measurement at e{sup +}e{sup -} colliders, and thus accessing the contact interaction scale {lambda}{sub ee}{approx}25 TeV.
