  We consider models for physics beyond the standard model in which
supersymmetry is broken spontaneously near the weak scale by fields that are
charged under electroweak symmetry. We show that this is possible if some or
all of the light quarks and leptons are composite near the weak scale.
Flavor-changing neutral currents can be naturally suppressed by a GIM mechanism
or by approximate flavor symmetries. CP and B violation may be suppressed by
accidental symmetries. We give a general effective field theory analysis of
such models, and argue that they can be phenomenologically acceptable and lead
to interesting observable signals in future experiments. We then construct
explicit models based on non-perturbative effects discovered by Seiberg.
