The below link is a directory, organized by sector, with the contact info and projects volunteers currently serving in Peace Corps Tanzania. It is the responsibility of each class' VAC representatives to collect and update this information every 6 months. If you do not see your projects listed or would like to update projects before your representative contacts you, please feel free to contact them individually.
The goal of this directory is the give volunteers the ability to share project ideas and contact those who have completed a project which you may be interested in. Feel free to browse and contact any PCV!
