Institute of Directors membership requirements

Every criterion Institute of Directors publishes, with its source, the date it was verified and how confident we are in it, plus superseded figures, so you can see how the tests have moved.

Read a requirement as the organization's published floor, not as a promise. A revenue test may have alternative versions for different business types, chapters can set stricter local tests, and invitation-only bodies publish criteria that describe members rather than admit them.

Membership is open rather than vetted against a financial threshold; the tiers differ by role and location, not by company size.

How admission works

Application process

Prospective members choose a tier and join online; there is no interview, sponsor requirement or financial vetting. A free registration option gives access to sample resources without membership. Corporate memberships are arranged by contacting the IoD directly.

Invitation required

Sponsor required

Selectivity

Not applicable in the usual sense: membership is open to directors, aspiring directors and those who work closely with directors, and the IoD publishes no acceptance rate. Selectivity applies to the separate Chartered Director qualification rather than to membership.

Membership term

Annual, with monthly instalments available for full membership over a fixed twelve-month period

Primary audience

Practising executive and non-executive directors in the private, public and third sectors in the UK, plus aspiring directors and directors based overseas

Typical member

Practising executive and non-executive directors or equivalents, ranging from start-up founders to directors of multi-million pound businesses and senior civil servants. Associate membership covers aspiring directors, former directors and those who work closely with directors; a student tier covers students.

Do you appear to meet them?

The qualification tool reads these rows against a profile you give in ranges and explains which criteria appear met, unclear or unmet. Check your profile

If not: alternatives to Institute of Directors (C200, NAWBO, TEC Canada, Business Roundtable).
