Star Alliance has two premium levels (Silver and Gold), based on a customer's status in a member's frequent-flyer program. Member and regional airlines recognize Star Silver and Gold status, with a few exceptions mostly about airport lounge access. Membership is based on the frequent-flyer programs of the individual airlines. Many members have a premium status with their individual airline program that goes beyond Gold, however these levels are all grouped together as Gold status when being recognized by Star Alliance overall.
