Abstract. A block method for solution of third order initial value problems of ordinary differential equations is presented in this paper. The scheme was derived using collocation and interpolation approach to generate a continuous linear multistep method which was solved for the independent solution to give a continuous block method. The result was evaluated at selected grid points to give a discrete block which gave simultaneous solutions at both grid and off grid points. The stability and convergence of the method were investigated, and found to be A -stable with good region of absolute stability. The accuracy of the block method was established numerically after comparing it with the existing method.
