The OAM association has a limited jurisdiction and an elected chair and vice-chair.

The present chair is Tonko Grever and the vice-chair is Judikje Kiers (director of Amsterdam Museum).

The foundation Samenwerkende Amsterdamse Musea (SAM) represents the collective business interests of the OAM.

All of the heads of marketing and communication of the forty-four partner museums are involved in MOAM.

The Museum Night (Dutch: Museumnacht, N8) was initiated by the MOAM, but has now become an independent organisation.
