Our clients

For over 40 years, Tetra Tech’s international development team has devised solutions to many development challenges across the Asia Pacific region and the world. We work with our clients in the public and private sectors to help the achieve effective and sustainable development outcomes.

Our commitment to effective international development

As a trusted implementation partner to government and multilateral donors, we bring a robust approach to the design of our programs to ensure the best development outcomes. With our support, projects and local organisations are equipped with practical tools to monitor the progress of their work and make changes when required so they can achieve results.

And we measure development effectiveness. We’ve conducted more than 600 evaluations for clients such as the European Commission, Department of Foreign Affairs and Trade (DFAT), MFAT, the UK Foreign, Commonwealth, and Development Office, the U.S. Department of State and the U.S. Agency for International Development. The evaluations help donors learn lessons they can apply to future policies and programs, while evidence of what works and what doesn’t, can be shared more broadly, so that the best ideas and practices are emulated.
