The phenomenology associated with gauge-mediated supersymmetry
breaking is presented.
A renormalization group analysis of the minimal model
is performed in which the constraints of radiative electroweak
symmetry breaking are imposed.
The resulting superpartner and Higgs boson spectra are highly
correlated and depend on only a few parameters.
Superpartner mass ratios and sum rules are identified
which can be tested at future colliders.
Some of these relations are logarithmically sensitive
to the messenger scale,
while others allow gauge-mediation to be distinguished from other
schemes for transmitting supersymmetry breaking.
Deviations from the minimal model, such as larger messenger
representations and additional contributions to Higgs
sector masses, can in some circumstances dramatically
modify the low energy spectrum.
These modifications include a slepton or Higgsino as the lightest
standard model superpartner, or exotic mass relations among
the scalars and gauginos.
The contribution to $b \to s \gamma$ and resulting
bound on superpartner masses are also presented for the minimal model.
Finally, the unique collider signatures of
heavy charged particle production, or
decay to the Goldstino within a detector are discussed.
