As an organisation, SIAA works to develop and build capacity internally. Measuring SIAA’s impact is central to this strand of work. SIAA measures its impact against the six core ‘intermediary functions’ detailed in Evaluation Support Scotland’s resource, ‘Understanding the Impact of Intermediaries’.

SIAA holds the Lasting Difference Symbol which demonstrates SIAA’s commitment to organisational sustainability, resilience, and development. The Lasting Difference Symbol was awarded to SIAA in February 2021.
