  There have been several important recent developments in precision
electroweak tests. These include: the new LEP energy scan during the 1993 run;
the first high-precision results on the left-right asymmetry from the SLD
Collaboration at SLAC; the probable discovery of the top quark by the CDF
Collaboration at Fermilab and the determination of its mass. I will discuss the
implications of these and earlier results for testing the standard model; for
the standard model parameters, including the top quark mass, the Higgs mass,
the weak mixing angle, and the strong coupling constant, $\alpha_s$; and the
search for new physics. In particular, given the CDF direct determination of
$m_t$ it is now possible to severely constrain certain types of new physics by
separating the contribution from new physics from the dependence on $m_t$.
