Dynamic Universal Pickleball Rating (DUPR) is the official rating system for pickleball leagues and tournaments of the Quad City Tennis Club. DUPR Days’ purpose is to allow players who want to get a rating to be officially rated. We do this by putting players in groups of similar skill level and move them to courts depending on their wins and losses. All scores will be automatically uploaded to DUPR. It takes a week for the rating to be generated in the DUPR website.
