Outreach, in its broadest sense, includes two separate roles. One is the outreach worker on the street working directly with the homeless, building trust, obtaining initial data and contact information, and encouraging them to accept services.
The second role is a quasi-office job, that of the Service Coordinator Specialist (SCS). Their role is to collect further data on the homeless individual, establish an Individual Recovery Plan (IRP), get them into the services that start them on their road to recovery, and monitor their progress.
These are overlapping functions that need close teamwork but require different skill sets and have different daily routines. There are cases where the roles may be combined, but most successful outreach work occurs when the roles are done by different, though closely coordinated, individuals. It is hard enough to find good outreach workers who can work the street; expecting them to also do consistent evaluations and data entry -- while talking to a homeless person on a cold, wet sidewalk -- is not realistic
Currently, some outreach groups have both these functions; some do not. Data collection is sporadic, and when done is often only to collect name, ethnicity, and gender. This is relatively easy to do and might meet HUD reporting requirements, but it does little to help the homeless or provide useful data to improve the system.
