Dictionary of Occupational Titles
The Dictionary of Occupational Titles (DOT) is a U.S. Department of Labor reference that classifies over 12,000 occupations (U.S. Department of Labor, 1991) by title, code, physical demands, working conditions, and specific vocational preparation (SVP).
When it is used
DOT remains a core reference in vocational evaluation, Social Security disability determinations, and transferable skills analysis.
Step-by-step
- Identify the DOT code for the occupation at issue
- Review the strength rating, physical demands, environmental conditions, and SVP
- Cross-reference with O*NET for updated occupational information
- Apply restrictions to determine suitability
Data sources
- DOT (published 1991, selected supplements)
- SCODDOT (Selected Characteristics of Occupations Defined in the DOT)
Limitations
The DOT has not been comprehensively updated since 1991. Best practice is to cross-reference with O*NET, particularly for newer occupations.
Admissibility
DOT-grounded opinions are widely accepted, with courts often expecting cross-referencing with O*NET where appropriate.
Frequently Asked Questions
Why is the DOT still used if it is not current?
DOT remains the standard reference for SSA disability adjudication and retains detailed physical demand and SVP information not fully replicated in O*NET.
