Deputy Assistant Secretary is a title born by government executives in certain countries, usually senior officials assigned to a specific Assistant Secretary.
United States
In the United States, the rank of Deputy Assistant Secretary denotes a senior executive service (SES) official within the United States federal government who reports to an Assistant Secretary. Career deputy assistant secretaries are generally appointed by the Cabinet Secretary who heads the department. Non-career SESs are appointed by the President of the United States and are assigned to specific department. In sub-cabinet agencies, headed by an administrator or director rather than a secretary, a comparable position is referred to as a deputy assistant administrator or deputy assistant director.
