At the Centre for Social Impact, we believe that strong, well-connected and supported leaders are essential to a thriving for-purpose sector. Social Impact Leadership Australia (SILA) is a ground-breaking national capacity building and leadership program designed to equip CEOs with the tools, networks and confidence they need to thrive – as individuals, as leaders of organisations, and as catalysts for systems change.
A critical part of the investment from both SILA’s philanthropic partners and CSI is ensuring the program is independently evaluated. This is not only about continuous improvement, it’s also about understanding and sharing the broader impact of investing in social purpose leadership.
To support this, we engage Nous Group to independently evaluate the program each year. These evaluations assess SILA’s impact at the individual, organisational and systems level, drawing on insights from CEOs, their teams, boards, and wider networks. The evaluations provide rich, evidence-based insights into what’s working, what’s evolving, and where we can improve.
Nous Group has produced annual evaluation reports, and a summative evaluation of SILA’s first three cohorts. In addition, CSI has developed annual infographics to share the results. We’re proud to publicly share these materials as part of our commitment to transparency and continuous improvement.

Below you can find an overview of each SILA cohort evaluation, highlighting key insights, survey results and our world class Net Promoter Scores.



We want to thank the SILA participants and others who have generously committed their time to providing this invaluable feedback. Their honesty and insights have directly informed how SILA continues to evolve and improve.
The Stories behind the data
Alongside the formal evaluations, we also capture the human stories of transformation that bring the data to life. These reflections from CEO participants explore the deeper, more personal impact of the SILA journey. You can explore these on our Stories of Social Impact page, where leaders share – in their own words – how SILA has shaped their leadership and the organisations they lead.
