# Event Calendar — QA Policy Reform Study

**Shared event (all sampled programmes):**
Ministry of Education Quality Assurance Policy Reform announcement —
March 2022. All programmes in the sample were notified of the new
accreditation criteria simultaneously on this date.

**Note for instrument designer:** Retrospective items should anchor recall
to "before/after the March 2022 QA Policy Reform announcement" rather
than using floating calendar years (e.g., "since last summer" or "in the
past 6 months"), because the sample's internal event distribution is
homogeneous on this shared date.
