Theory of Change Without the Jargon

Theory of change has become an unloved phrase. Most documents that use it are written in a dialect of funder English designed to satisfy a grant application and then ignored. That is a wasted asset. A good theory of change should be one of the most-used pages in the charity: cited in trustee meetings, referenced in funding decisions, posted on the intranet, and updated when reality forces a correction.

The version that gets used is shorter, plainer, and more honest about assumptions than the version most funders see. It also takes about a day to write if you facilitate it properly.

The one-page structure

Five sections, no more:

1. The problem we exist to address, in one sentence the team agrees with.
1. The change we are trying to create, in one sentence stated in the words of beneficiaries.
1. The activities we run that we believe cause that change.
1. The assumptions that have to hold for the activities to work.
1. The evidence that tells us each assumption is still true.

The fifth section is the one most theories of change skip and the one that determines whether the document survives contact with reality.

The workshop that produces it

Morning: the problem and the change

Two hours. Senior team and at least two trustees. Start with the problem. Ask everyone to write it in one sentence, anonymously. Surface the differences. Discuss until you have a sentence the room genuinely agrees with. Repeat for the change you are trying to create, this time in the voice of the people the charity serves.

Afternoon: activities, assumptions, evidence

Three hours. List every activity the charity runs (programmes, advocacy, communications, fundraising). For each, ask: what has to be true for this to produce the change we just described? Those are your assumptions. For each assumption, ask: how would we know if it stopped being true? That is your evidence list.

Closing: prioritise and write up

Half an hour. Three to five activities that carry most of the weight. Three to five assumptions that the leadership team commits to monitoring quarterly. One page. Print it. Put it on the wall.

Where most theories of change go wrong

They hide the assumptions

Funders rarely insist on assumptions; consultants rarely surface them. But the assumptions are where the strategy actually lives. "If we run more workshops in Bradford, more young people will access mental health support" is an assumption with at least four embedded claims (supply, demand, awareness, capacity). All four are testable. None get tested if the document does not name them.

They use language nobody on the team uses

If staff cannot quote the theory of change in their own words, it is not theirs. Phrases like "systemic upstream intervention" and "cross-sectoral catalytic change agent" are warning signs. The plainer the document, the more likely it is to be referenced.

They never get updated

Reality moves. Funding environments shift. New evidence emerges. A theory of change written in 2022 and never reviewed by 2026 is a museum piece. Treat it like a board policy: dated, owned, scheduled for review.

How to use it day-to-day

Four sensible disciplines:

• Every new programme proposal references which activity in the theory of change it supports, or explains why it is a deliberate expansion.
• Every funding application starts from the theory of change rather than the funder brief.
• Every six months, trustees review the assumptions: are they still true? What evidence have we gathered?
• Every annual report opens with the theory of change and reports against the assumptions.

A theory of change earns its keep on the days the charity faces a hard decision. If it is not in the room when the senior team is choosing which programme to close, it is the wrong document.

A worked example, briefly

A small literacy charity might write: "We exist because too many children in our city leave primary school unable to read for pleasure. We want every child to leave primary school choosing to read a book of their own free will. We run after-school reading clubs, parent workshops, and teacher training. We assume that parents have time and confidence to read at home, that schools will host clubs, and that children currently turned off reading can be turned back on. We will know our assumptions hold if club attendance is rising, parent workshop ratings are above 4 out of 5, and teachers report increased independent reading in class."

Half a page. Every sentence does work. Every assumption is testable. Every test has a data source the charity already collects or could collect cheaply.

The 30-day implementation plan

1. Week 1: Schedule the workshop. Pre-read sent to attendees one week ahead.
1. Week 2: Run the day. Capture the one page on flip-chart paper before leaving the room.
1. Week 3: Type up, circulate to the room for sign-off, design as a single page.
1. Week 4: Publish on the intranet, print and display, reference in the next board pack.

Most charities can produce the version that gets used inside a month. The hard part is the workshop facilitation, not the writing. If you cannot facilitate it internally, that is the single point worth spending money on; the rest is your own thinking.
