This report provides an update of the skills ratings procedures. These methods for Cycle 12 were modified to take into account occupations that have been previously rated in earlier cycles. New occupations, rated for the first time, used previously established procedures. Modified procedures were used for occupation being rated for a second time so that previous ratings could be included in the rating process. These modified rating procedures will be used in the future, since the majority of occupations will have been rated at least one time.
