Formative evaluation

Formative evaluation is generally any evaluation that takes place before or during a project’s implementation with the aim of improving the project’s design and performance.

Formative evaluation complements summative evaluation and is essential for trying to understand why a program works or doesn’t, and what other factors (internal and external) are at work during a project’s life.

Formative evaluation does require time and money and this may be a barrier to undertaking it, but it should be viewed as a valuable investment that improves the likelihood of achieving a successful outcome through better program design

Why Undertake a Formative Evaluation?

There are a number of good reasons to conduct a formative evaluation and we have outlined some of these below:

  • Without formative evaluation, you may be embarking on a project that may not meet a real need, or one that may be constrained by external factors that you cannot control.
  • Formative evaluation is especially important in community engagement and behaviour change projects as such interventions are often complex and therefore require careful monitoring of processes in order to respond to emergent properties and any unexpected outcomes.
  • Forsaking formative evaluation may also mean that you are not able to observe and capture feedback that may improve the implementation of a project, and therefore its chance of successfully achieving the desired outcomes.
  • Formative evaluation allows you to develop a better understanding of the process of change, and finding out what works, what doesn’t, and why. This allows you to gather the knowledge to learn and improve future project designs and implementation.

Categories of formative evaluation

There are several categories of formative evaluation. Proactive and clarificative evaluations can also be referred to as ex-ante evaluations (meaning before the event).

Categories of formative evaluation

Pre-project Project development

Why To understand or clarify the need for the project To make clear the theory of change that the project is based on To improve the project’s design (continual improvement) as it is rolled out To ensure that the project activities are being delivered efficiently and effectively

Formative evaluation often lends itself to qualitative methods of inquiry. The questions asked in formative evaluation are generally more open and lead to exploration of processes, both from the viewpoint of participants, but also from that of project staff and other stakeholders. The use of participatory evaluation is particularly relevant and appropriate to formative evaluation. Some of the approaches to consider in undertaking a formative evaluation are briefly outlined in this section.

It is considered good evaluation practice to include both formative and summative evaluation.

Please make a donation to upgrade the Evaluation Toolbox.

The Evaluation Toolbox is maintained by Damien Sweeney and Martin Pritchard from PREA as their in-kind contribution back to the community. The Toolbox now needs several weeks of work to review and upgrade all the contents and add new content for you. Work has begun and we are seeking your donation (big or small) to help support this major upgrade. Email us to indicate what you want to be included in the Toolbox.

What is the Toolbox?

The toolbox aims to provide a one-stop-site for the evaluation of community sustainability engagement projects that aim to change household behaviours. Through the toolbox you can learn how to conduct your own evaluation of a behaviour change project using the guides and templates provided.

Why Evaluate?

Conducting an evaluation is considered good practice in managing a project.

The monitoring phase of project evaluation allows us to track progress and identify issues early during implementation, thus providing and opportunity to take corrective action or make proactive improvements as required.
