Winners of the Indianapolis 500 Rookie of the Year Award, first awarded in 1952. No official award was given from 1911–1951, even though at least one rookie starter has been present in every running of the Indianapolis 500. The award is voted on by a panel of judges, which is composed of selected members of the media, historians, and a handful of other experts. The voting takes place the night of the race (or the morning after), and does not necessarily go to the highest-finishing rookie. Noteworthy accomplishments during qualifying, regardless of the respective race result, have frequently been a factor in voting. A rookie who competitively runs up front during the race, passes many cars, and/or leads laps (but ultimately drops out) can also garner consideration over another rookie who finished higher, but did so merely by surviving attrition. Other contributing attributes can include personal attitude, sportsmanship, professionalism, and interaction with driver coaches, fans, and media. Years in which two drivers are listed indicate co-winners, due to a tie in the final voting.
