Under the Sixth Edition this is a compliance question with a clock on it, not just an HR problem. No single standard is labeled succession planning. The expectation is distributed across the A standards, which hold the sponsoring institution accountable for ensuring effective and continuous program leadership, and the E standards, which set the notification timelines a transition triggers.
Those E-standard timelines are measured in business days, not months, and they are where transitions turn into cascading citations. A vacancy triggers notification. Notification triggers an interim appointment inside a defined window. The interim appointment triggers portal access, website updates, official contact changes, and recruitment reporting. A program that has not pre-authorized a second person on the ARC-PA Portal will miss the first deadline while it requests access, and every downstream obligation slips behind it.
A written plan is necessary and not sufficient. The plan has to be executable tomorrow: named interim leadership, defined appointment procedure, multiple people already holding system access, shared departmental email so information does not silo, and current documentation of calendars, reporting schedules, and institutional contacts. Program websites deserve specific mention, because outdated leadership listings are a routine source of findings that nobody notices until a reviewer does.
The strongest version of succession planning is structural rather than documentary. Assistant director roles with real delegated responsibility for didactic education, clinical education, assessment, or operations develop leadership capacity while it is still theoretical, and they reduce the single-director burden at the same time.
