There is increasing evidence to suggest that energetic particles observed in ``gradual'' solar energetic particle (SEP) events are accelerated at shock waves driven out of the corona by coronal mass ejections (CMEs). Energetic particle abundances suggest too that SEPs are accelerated from in situ solar wind plasma rather than from high temperature material. We present here a a dynamical time dependent model of particle acceleration at a propagating interplanetary shock. The model includes the determination of the particles injection energy, the maximum energy of particles accelerated at the shock, energetic particle spectra at all spatial and temporal locations, and the dynamical distribution of particles that are trapped in the post shock flow and those that escape upstream and downstream from the evolving shock complex. .
