Ohio's Value-added system uses an advanced methodology (Education Value-added Assessment System-EVASS) initially formulated by William Sanders and further developed by Sanders and colleagues at SAS Institute, Inc. These procedures, while computationally complex, have a substantial body of empirical testing in research literature to support them.
