The current version of the Squire state court of last resort professionalization index is regularly used in studies of state courts. We have updated the index for 2019, producing a second and more recent index. Given the relative stability between this index and its predecessor, it is unlikely that many findings will change. During the 15 years that lapsed between the first index and the more recent one, little changed in most states, while reforms in a few places substantially shifted the relative standing of their court of last resort. It seems unlikely that the nation will experience any sweeping reform movements impacting state courts of last resort across the board. The more likely scenario is the sort of idiosyncratic changes impacting a few courts that were witnessed over the last decade and a half. Thus, looking to the future, it may be prudent to update the index every 5–10 years to capture any notable alterations.
