BASE is a membership organisation for supported employment agencies and supported businesses in the UK. BASE was formed in 2006 through the merger of the National Association of Supported Employment and Association for Supported Employment. It was felt that a unified voice was essential to protect the interests of the industry and to develop best practice within it. The Association has developed a nationally accepted definition of Supported Employment. This offers a guideline to good practice, with its basic requirement that employment should mean integration into a regular work setting.
