Recommendation memos

4/17/2012 This measure category should be classified under review. The measure sunset criteria should be changed to March 2013 (at which time new data should be used to develop the baseline and efficient-case EF values). In addition, there are minor workbook structure and documentation improvements that should be made. Once these have been implemented or resolved, the measure can be returned to the classification active.
