"After months of careful consideration, the ESRB will be switching from part-time to full-time raters in April 2007," Vance said. "Having full-time raters will allow for each one to have greater experience actually reviewing content and recommending ratings, given the increased amount of time each one would spend doing it. This would provide each rater with a greater sense of historical parity for ratings, not to mention helping them to be more attuned to pertinent content and how it should be considered from a ratings standpoint. The full-time raters would also be responsible for play-testing final versions of the game, time permitting, which would allow for ESRB to play-test a greater number of games than it currently does. We'll have more information available about these changes at a later date."
