In this paper, we propose a hybrid initial-value technique for singularly perturbed boundary value problems. First, we develop a hybrid scheme to solve the singularly perturbed initial-value problems, and then, the hybrid scheme is used to solve the singularly perturbed boundary value problems. The scheme is shown to converge to the continuous solution uniformly with respect to the perturbation parameter. Necessary error estimates are derived for the scheme. To verify computational efficiency and accuracy, some numerical examples are provided.
