Final answer:
Time in grade (TIG) is computed at the rate of one-half point per month in grade up to 10 years in the Weighted Airman Promotion System (WAPS). Once a service member reaches 10 years of TIG, they will have accumulated the maximum TIG score of 60 points. TIG is just one component considered in the WAPS promotion system.
Step-by-step explanation:
Time in grade (TIG) is a concept used in the Weighted Airman Promotion System (WAPS) to determine a service member's eligibility for promotion. In the WAPS system, TIG is computed at the rate of one-half point per month in grade up to 10 years. This means that for each month a service member serves in a particular grade, they earn half a point towards their TIG.For example, if a service member has been in a grade for 36 months, they would have earned 18 points towards their TIG (36 months x 0.5). However, once a service member reaches 10 years of TIG, they will have accumulated the maximum TIG score of 60 points.It is important to note that TIG is just one component considered in the WAPS promotion system, along with other factors such as time in service and the Promotion Fitness Examination (PFE) score. The cumulative score from these factors determines a service member's eligibility and placement in the promotion ranking.
