Doctor of Business Administration

The Doctor of Business Administration (abbreviated DBA, D.B.A., DrBA, or Dr.B.A. or BusD) is a research doctorate awarded on the basis of advanced study and research in the field of business administration. The D.B.A. is a terminal degree in business administration. Along with the Ph.D, it represents the highest academic qualification in business administration. Successful completion of a D.B.A. or Ph.D in business administration is required to gain employment as a full-time, tenure-track university professor or postdoctoral researcher in the field. As with other earned research doctorates, individuals with the degree are awarded the academic title doctor, which is often represented via the English honorific ``Dr.'' or the post-nominal letters ``D.B.A.'', ``DBA'', ``Dr.B.A.'', or ``DrBA''.
