Provincial Grand Lodge of Mark Master Masons of Hertfordshire

The Society is governed by three Grand Master Masons who traditionally hold their offices ad vitam, but waive that right. The First Grand Master Mason retires after a tenure of five years and the Second Grand Master Mason after a period of three years (although both are eligible for reappointment), whilst the office of Third Grand Master Mason terminates annually with the enactment of the Ancient Drama one year after his appointment.

There are seven degrees in total.
