SIR vs SSR: what electoral-roll revision terms mean

The name of an exercise is only the starting point. Its order, dates and procedure matter.

The short explanation

SIR means Special Intensive Revision; SSR means Special Summary Revision. ECI’s revision FAQ distinguishes intensive, summary, and partly intensive/partly summary revision. It describes SSR as summary revision with special features, including intensive pre-revision activities.

House-to-house verification therefore does not, by itself, identify an exercise as SIR. ECI’s SSR description also includes that activity.

Draft, claims/objections and final publicationThese are stages, not interchangeable lists or outcome measures.
Later orders and supplementsAn earlier timetable or document checklist may have been modified.

How ECI describes SSR

The FAQ separates pre-revision work from revision itself. It describes draft publication, claims and objections, processing of additions/deletions/corrections, and final publication. That procedural description is not evidence that every individual case was correctly handled.
