Several notions of convergence for subsets of metric space appear in the literature. In this paper, we define Wijsman -convergence and Wijsman -convergence for sequences of sets and establish some basic theorems. Furthermore, we introduce the concepts of Wijsman I-Cauchy sequence and Wijsman -Cauchy sequence and then study their certain properties.
