Each organizations or programs needs to adapt it to their own needs. The correct spelling of the volunteer's name, work and home address and where they prefer to receive their mail from the organization. Phone numbers, FAX and e-mail can also be useful. Age, marital or partnership status, race, sex are all information you may want to keep. This information is NOT on the application, but is provided only after someone becomes a volunteer.
Demographic information helps build balance in programs.
Most people are happy to provide it. Education level and major is like demographics, it tells where you volunteers are coming from. It can also be used if you need a volunteer with a specific skill. Ask people to provide a work and volunteer history. Previous experience can help in appropriate placements for a new position.
