We live in a changing world where communities around the globe are experiencing social, economic, and political transitions. At Tetra Tech, our work demands that we understand both our clients and the needs of local communities and organizations with which we work. We lead with science in our international development projects by making data-based decisions to provide sustainable solutions for the communities and nations we serve.

Through the use of monitoring and evaluation, we learn and adapt to the local context in which we work. We create evidence-based approaches to provide technical and advisory services for more than 200 projects in more than 100 countries. Working in partnership with business, local and non-governmental organizations, government agencies, and donors, we achieve locally derived development solutions worldwide.
