I propose that the large mass splitting between the top and bottom quarks is a signature of a class of superstring derived standard-like models. In these models only +2/3 charged quarks obtain a trilevel mass term. Mass terms for the lighter quarks and leptons are obtained from higher order terms in the superpotential. These models contain an ``anomalous`` U(1) gauge symmetry. Application of the Dine-Seiberg-Witten mechanism cancels the anomaly leaves a cubic level mass term only for the top quark.
