Theory
of Change
A methodology used across governments, international development, and the social sector to plan interventions that actually work. Today: what it is, who uses it, and why understanding it now changes how you approach the rest of this course.
Why Are We Talking About This Now?
You are in the Describe phase. The intervention phase does not begin until week 9. So why introduce Theory of Change now?
Because knowing where you are headed changes how you work right now. Theory of Change demands something very specific before you can begin: a deep understanding of the phenomenon you want to change. That is exactly what the Describe phase builds.
By the end of today you will understand why every session between now and week 9 builds the foundation your intervention will stand or fall on.
What Is Theory of Change?
"A rigorous yet participatory process whereby groups and stakeholders in a planning process articulate their long-term goals and identify the conditions they believe have to unfold for those goals to be met."
The central, fundamental idea: start with where you want to end up, then map backwards to figure out how to get there. Every step in the chain must be argued with evidence rather than hoped for or assumed.
This separates ToC from a wish list. You are building a testable causal argument for why your intervention will produce the change you intend.
Outcome first · Method second
Quick Check
Which best describes the Theory of Change approach?
Correct. ToC works backwards from impact. Options A and C describe forward planning, the conventional approach ToC explicitly rejects. Option D describes one activity within a ToC process, not the approach itself.
Not quite. Theory of Change is defined by backward mapping: you begin with the long-term outcome you want, then work backwards through the conditions that must be met. Try again.
The Causal Pathway
A ToC maps a chain of outcomes from your ultimate goal down to the things you can directly do. Each link carries an assumption about how change happens, and that assumption needs evidence.
Assumptions
Every link in a causal chain rests on an assumption, a belief about how change works. Making assumptions explicit is what separates a Theory of Change from wishful thinking.
For every assumption, you need a rationale: the evidence or reasoning that justifies it. This is where disciplinary knowledge matters: psychology, economics, and politics each illuminate different assumptions.
Causal link: "If we build more public libraries in underserved areas, literacy rates will improve."
Hidden assumptions: Literacy is limited by access to books (rather than by teaching quality, time, or motivation). People in these areas will use the libraries. The books will be in languages people read. Library staff will be trained to support new readers.
Each of these assumptions needs evidence. Without it, the link is only hope.
Spot the Assumption
Select all statements that are hidden assumptions in this link, then check.
A, C, and D are assumptions embedded in this causal link. A assumes demand exists. C assumes the stadium association reads as neutral rather than exclusionary. D assumes a mechanism: co-presence becomes connection. B is contextual rather than a causal assumption within this link. E is a resource question rather than a question of causal logic.
Three Tests for a ToC
Any Theory of Change must pass three quality tests. When you build yours in weeks 9-14, these are the standards you will be held to.
A ToC that fails any one of these tests needs rework. Plausibility without feasibility is academic. Feasibility without testability is faith. Notice: plausibility requires evidence about the problem, which is what description produces.
Who Uses Theory of Change?
ToC is standard professional practice across your future career post-PEP.
A Career Skill
You are studying Psychology, Economics, and Politics. Each discipline feeds directly into Theory of Change practice.
Learning to build a Theory of Change is a transferable skill that employers in these fields expect you to have.
What Happens When You Skip Description
The most common failure mode in applied work is premature intervention: jumping to solutions before the problem is understood. These are real examples. Click each to see what went wrong.
Why We Describe First
Theory of Change begins with a clearly defined long-term outcome. But you cannot define a good outcome without understanding the phenomenon you want to change.
If you do not understand the third place (what it is, how it works, why it declines), you cannot define what a successful intervention looks like. And if you cannot define success, you cannot map backwards from it.
The verb sequence is the structure that prevents you from becoming the next PlayPumps.
