Impact Evaluation

Some companies and social compliance initiatives have begun to consider impact evaluation as a way to determine the long-term development impact of their efforts to reduce child labor, forced labor and other labor rights violations in their supply chains.  Impact evaluation is a method that establishes, with statistical rigor, a causal linkage and quantifiable impact of a specific intervention.  Impact evaluation isolates the effects of a program or service by comparing a treatment group (those exposed to the program or service) to an identical group that does not receive the program or service.

Example In Action

Better Work Impact Evaluation

As part of its monitoring and evaluation activities, Better Work has developed a long-term impact evaluation methodology with a multidisciplinary academic team from Tufts University. The methodology evaluates project outcomes beyond the factory or industry level.  In certain countries, the study team is using the methodology to look at both managers and workers to assess human development and economic development indicators. In other countries, impact measurement will analyze year-to-year changes in factory performance or use more qualitative research methods.

For more information, see the Better Work website.

It should be noted that, while review and assessment methods like independent monitoring, independent verification and impact evaluation can verify that companies have robust systems in place to reduce the likelihood of child labor, forced labor and other labor abuses in supply chains, none of these methods guarantees that these abuses are not present.
