For retirement, eligibility is at age 62. If a person reaches age 62 in 2015, for example, then 2015 is the person's year of eligibility. We always index an individual's earnings to the average wage level two years prior to the year of first eligibility.Thus, for a person retiring at age 62 in 2015, we would index the person's earnings to the average wage index for 2013, or 44,888.16.o determine the national average wage index for 2013 at a level that is consistent with the national average wage indexing series for prior years, we multiply the 2012 national average wage index of 44,321.67 by the percentage change in average wages from 2012 to 2013 (based on our tabulated wage data).
These scores are derived from the total raw scores for each test and are on a normalized score scale that has a mean of 10 and a standard deviation (SD) of 3. A scaled score of 10 describes the average of a given age group.
Standard Scores are scores that have a fixed mean and standard deviation in the population of examinees. A Standard Score indicates how many units of the standard deviation a particular score is above or below the mean. In the case of the ASVAB subtests, the mean is set to 50 and the standard deviation is set to 10.Thus, a Standard Score of 40 indicates that the examinee scored 1 standard deviation below the mean. Standard Score indicates how many units of the standard deviation a particular score is above or below the mean. In the case of the ASVAB subtests, the mean is set to 50 and the standard deviation is set to 10.
