Final answer:
The personnel data system (PDS) status code that identifies a re-evaluate for temporary duty (TDY) is 'R'.
Step-by-step explanation:
The personnel data system (PDS) status code that identifies a re-evaluate for temporary duty (TDY) is R.
When a servicemember is on temporary duty, their PDS status code will be set to 'T' to indicate the temporary duty assignment. If there is a need to re-evaluate the assignment, the PDS status code will be changed to 'R'.
For example, if a servicemember was assigned to temporary duty in Europe, but there is a change in plans and the assignment needs to be re-evaluated, the PDS status code will be changed to 'R'. This change in status will prompt a review of the assignment and a potential re-assignment or adjustment of the original temporary duty assignment.
