In the USA, in some states it is DOR = Dept. of Rehabilitation, in others DVR = Dept. of Vocational Rehabilitation. In CA, they used the latter title for year, but recently changed it to DOR.

Just to throw some more letters in the alphabet soup we are DRS in Virginia, Department of Rehabilitative Services.
Actually, in recent years they have merged with Aging Services and the agency is now called," The Department for Aging and Rehabilitative Services". Not aware of any acronym for that one.
