In the United States, a large portion of social services (shelter for the homeless, job training, etc.) are handled by independent (i.e., non-governmental) agencies. Most of these agencies focus on a particular area of need, such as employment or housing. Therefore, a large part of a social worker's job is to provide referrals to other agencies. For example, a social worker at a job training agency might refer a client to an agency that provides free clothing (for job interviews, etc.). Sometimes, a referral is an official document, such as a letter signed by the social worker making the referral. Often, though, a referral is simply information about another agency: the social worker writes down the phone number / address of another agency, passes it on to the client, and explains what service(s) the other agency provides. How is referral translated in your language?
