  This paper summarizes several developments in string-derived (Minimal
Supersymmetric) Standard Models. Part one reviews the first string model
containing solely the three generations of the Minimal Supersymmetric Standard
Model and a single pair of Higgs as the matter in the observable sector of the
low energy effective field theory. This model was constructed by Cleaver,
Faraggi, and Nanopoulos in the Z_2 x Z_2 free fermionic formulation of weak
coupled heterotic strings. Part two examines a representative collection of
string/brane-derived MSSMs that followed. These additional models were obtained
from various construction methods, including weak coupled Z_6 heterotic
orbifolds, strong coupled heterotic on elliptically fibered Calabi-Yau's, Type
IIB orientifolds with magnetic charged branes, and Type IIA orientifolds with
intersecting branes (duals of the Type IIB). Phenomenology of the models is
compared. To appear in String Theory Research Progress, Ferenc N. Balogh,
