A general selection theorem for a Vietoris‐like hyperspace topology is obtained and, as a result, several known selection theorems for both ‘topology’‐ and ‘metric’‐generated hyperspace topologies are improved from a common point of view. Applications are presented in characterizing classes of metrizable spaces by continuous selections for their hyperspaces. 1991 Mathematics Subject Classification: primary 54B20, 54C65; secondary 54E45, 54D65, 54E40, 54C10, 54G12.
