The DOT was created by the Employment and Training Administration, and was last updated in 1991. It is included on the Office of Administrative Law Judges (OALJ) web site because it is a standard reference in several types of cases adjudicated by the OALJ, especially in older labor-related immigration cases.

The DOT, however, has been replaced by the O*NET. For information on O*Net, see

Printed copies of the DOT may be purchased from the Government Printing Office/Superintendent of Documents' Online Bookstore (select the Sales Product Catalog, and search for "Dictionary of Occupational Titles").
