Common Foundations

Five essential practices

 The “how” of impact measurement

The Common Foundations provide guidance for how to measure impact. They are a minimum standard. Social purpose organizations can know when their impact measurement practices are ‘good enough.’

The essential practices for how to measure impact.

Plan your intended change

This plan specifies how, and why, your work will bring about change. A diagram—such as a theory of change, outcomes map, or logic model—is often used to illustrate the relationships between actions, performance, and results.

Use performance measures

Performance measures, known as indicators, are another common foundation of many impact measurement approaches. They help you to assess how well your work is carried out, and what effects it has.

Collect useful information

The information collected should be useful enough to you to make it worth the effort. This utility derives both from what information you collect, and from how it is collected, and how often.

Gauge performance and impact

In all impact-measurement approaches is the need to assemble and analyze data. Only through this analysis can you gain insights about what works, and about how well you are doing.

Report on results

The information you collect should be used to produce a balanced account of your work, and the difference it makes. This not only helps you to make better decisions about what to do next; it also allows you to communicate your achievements clearly and persuasively to others.

The Common Foundations of Impact Measurement

At their foundation, all the many tools and approaches to measuring impact share the same five essential practices. Read the essential practices in full. 

The Common Foundations self-assessment and online course have been invaluable for us. Both resources clearly mapped out the process of impact measurement while guiding us to break down essential practices into actionable steps. The questions in the assessment provoked reflections about where we are as a small startup and the online course guided us in mapping out how we might work to meet the attainable minimum standard.

A minimum standard

The Common Foundations set a minimum standard, not a gold standard.

Most impact measurement tools and approaches already use the essential practices. If your organization is already doing impact measurement, you probably won’t need to invest additional time, money or skills to align with the Common Foundations.

As long as all five practices are in place, the impact measurement process is good enough.

The Common Foundations are based on a global consensus

There is broad global consensus on the essentials of impact measurement practices. The Common Foundations are based on that global consensus. We followed the “Common Process” from the European Expert Group on Social Economy and Social Enterprise. This process is broadly similar to “Les six grandes étapes” outlined by Territoires innovants en Économie sociale et solidaire (TIESS). And this process was recommended by the Ontario Impact Measurement for Social Enterprise Task Force after consulting with many charities, social enterprises, funders and impact investors. We made a few small changes to the wording, but not to the substance. 


The Common Foundations are part of many impact measurement methods

At their foundation, all the many tools and approaches  to measuring impact share the same 5 essential practices. The Common Foundations are not new, they highlight what is common.

Theory of Change

Sustainable Livelihoods Approach

Logical Framework Approach

Results-Based Approach

Social Return on Investment

Demonstrating Value

and others.


The Common Foundations fit with other standards

The Common Foundations are compatible with other popular standards. This is not either-or it’s and. A social purpose organization can use the Common Foundations to enhance their work with:

Impact Management Project


B Corp


UN Sustainable Development Goals

Global Compact

Imagine Canada Standards

and others.

The Common Foundations are consistent with the Montreal Declaration on Evaluation and Social Impact Measurement.

How to align with the Common Foundations

The self-assessment can help your organization determine if it is meeting the minimum standard of impact measurement in Canada. If so, we invite you to say that you are. One way you can do this is by adding the Common Approach logo to your website and reports.


The Common Approach has developed a self-assessment to help social purpose organizations walk through the five essential practices. To complete the self-assessment, simply answer ‘yes’ or ‘no’ and find out if your organization meets the minimum standard.

The Common Foundations to Impact Measurement: Self Assessment Tool was a catalyst for an important discourse within our organization. The assessment was a quick, thorough and informative way to set a baseline for common practices in impact measurement that our organization could work on throughout our programming. This was especially important as a network organization where quantitative measures are hard to establish. We explored other means of describing our impact such as evaluating the process of change and this helps RCEN better explain our need and impact to future funders and donors.
