Measurements of the electroproduction of the \Delta(1232) resonance through the p(e,e^'p)\pi^o reaction have been performed. The data were taken with the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab using incident electron energies of 1.6, 2.4 and 4.0 GeV. Elastic and inelastic cross sections were measured simultaneously with continuous coverage over a large range of four-momentum transfer Q^2=(0.3-4.0 GeV^2). Decay angular distributions in the p\pi^o center-of-mass were obtained over the full range of cos\theta_c.m. and \phi_c.m.. The high statistical accuracy of this data set is expected to provide strong constraints on dynamic models of the N\rightarrow\Delta transition form factors. A preliminary partial wave analysis will be presented.
