The DEEP2 spectroscopic survey is a major effort to characterize galaxies at z ~1. A distinct advantage of this survey is the relatively high spatial and spectral resolution of the data, which allows us to measure spatially-resolved galaxy kinematics. We present first results from an effort to determine the Tully-Fisher relation (TFR) at 0.9 < z < 1.4 with a sample of 40 disk galaxies in the Extended Groth Strip for which we have rotation curves from DEEP2 spectroscopy as well as high-resolution HST (ACS) imaging. We describe the updated software we use to measure rotation velocities, accounting for seeing, orientation, and instrumental effects. Furthermore, we explore the evolution of the TFR in the context of theoretical expectations from models.
