There are two categories of membership Full and Associate:

Full membership of BASE is available to organisations and individuals who provide or facilitate paid employment, advice, guidance and training for people with a disability and/or other economic disadvantage

Associate membership of BASE is available to individuals over the age of 18 and organisations with an interest in supported employment and inclusive recruitment.

The difference between the Full and Associate memberships, is that voting at any regional, annual general or extraordinary meetings that may take place is only open to Full members of the Association. All members must agree to the aims and definitions in the association's memorandum and articles of association.
