This research summarizes work done by myself (Nucl.Phys.\bf A641 (1998)461), or in collaboration with R. M. Davidson (Phys.Lett.\bf B348(1995)163) and H. Weigel and L. Gamberg (Nucl.Phys.\bf B560(1999)xx). I will discuss several topics related with the computation of structure functions in the quark model in general and its perturbative evolution. In particular, I address this topic in the Nambu-Jona-Lasinio model of hadrons, where the nucleon is constructed as a soliton. I show that the handling of the regularization procedure is crucial in order to obtain exact scaling in the Bjorken limit and fulfillment of sum rules. I also include some problems concerning the general validity of quark model calculations.
