By using the idea of partial sharing of a set of meromorphic functions by a member of a family of meromorphic functions and its kth derivative we obtain a normality criterion generalizing some of the earlier results on shared sets and normal families of meromorphic functions. Further we prove a normality criterion which improves Marty’s theorem and its reverse counterpart.
