This paper reviews current theoretical work on the various stages of accretion in protostars, and the relationship of these ideal stages to the spectral classes of observed protostellar systems. I discuss scaling relationships that have been obtained for models of pre-stellar cores as they evolve by ambipolar diffusion toward a central singularity, and expectations for the dynamical evolution as the cores collapse radially to form a rotating disk. I summarize work that suggests accretion in T Tauri systems may be limited by ionization to disk surface layers, and implications for the variation of the disk accretion rate with radius. Finally, I describe models for the asymptotic structure of free magnetocentrifugal winds, and show that the constant-density surfaces in these winds may be strongly collimated even when the streamlines are not.
