Traditional theories of change often look neat on paper but fail in practice. The Actor-Based Change (ABC) Framework was created to fix that - putting the focus on the people and organisations whose behaviours actually drive change.
Since its publication in the American Journal of Evaluation, the framework has been applied to programs worldwide - from youth employment in Tunisia, to strengthening cybersecurity in Europe, to improving health services in Pakistan.
This is the first time the co-creators, Andrew Koleros and Mark Oldenbeuving, are teaching together in person.
A full-day immersive workshop with both creators
Practical tools and templates you can apply immediately
Guided work on your own program challenges
Networking lunch and breaks with peers
Follow-up support to help embed learning after the event
Practitioners, evaluators, and program managers who:
Work on complex social challenges
Want systems approaches that are practical, not abstract
Have found traditional frameworks limiting
Bring some program/evaluation experience (not a beginner’s intro)
Location: Mathematica Offices, Boston
Date: Thursday, October 9, 2025
Time: 9:00 AM – 5:00 PM EST
Limited to 20 participants for an interactive experience
