This report presents descriptive analyses on workforce trends in the 2012 National Registry Alliance Dataset, features an analysis examining the relationship of age with education level, and provides recommendations for registry functioning and policy development based on these findings. The 2012 National Registry Alliance Dataset consists of data from nine registries: Connecticut, Miami-Dade County (FL), Maine, Missouri, Montana, New Jersey, West Virginia, Wisconsin, and Wyoming. These registries followed the Partnership Eligibility Review (PER) guidelines for data submission. The dataset represents active registry participants as of January 1, 2010, through March 1, 2012, and includes individual records from 58,398 professionals (49,740 of whom were currently employed) working across 12,050 programs/facilities. Given this report's primarily descriptive nature, the issues of saturation--the extent to which a specific registry captures all programs and workers in the field for a given geographic region--and representativeness of registry data are not addressed. Further work regarding saturation and representativeness of registry data will be forthcoming from the National Registry Alliance. (author abstract)
