Non-equilibrium dynamics have attracted considerable attention in recent years. Most of the studies however have been restricted to systems with an infinite geometry. A first step towards a more realistic situation is to consider a semi-infinite system, in which one is particularly interested in the behavior close to the surface. I present here some analytical and numerical results, both for quenches below and onto the critical point. It turns out that certain known statements about critical exponents do not necessarily hold for the corresponding surface exponents.
