Key electroweak measurements performed by the SLD collaboration at the SLC are described and recent results given. The left-right cross-section asymmetry, A{sub LR}, has been updated to include the 1996 data. It remains the single most precise measurement of sin{sup 2}{theta}{sub W}{sup eff} and it is compared to the LEP results. The polarized differential cross section for b-quarks is measured and is used to perform a unique direct measurement of the parity violation parameter for b quarks, A{sub b}. The excellent capability to perform secondary vertexing at SLC with CCD-based vertex detectors is described, including first physics results with the new detector VXD3. The vertexing is used to full advantage to make a highly pure B tag to measure the fraction of hadronic Z{sup 0} decays going to b quarks, R{sub b}. The vertexing, in combination with electron-beam polarization, is used to measure B{sub d}{sup 0} mixing. The prospects for making a B{sub s}{sup 0} mixing measurement are excellent given good SLC performance in the upcoming SLC run(s). {copyright} {ital 1997 American Institute of Physics.}
