Student Design Teams apply to ATC for an appropriate design challenge to be implemented at an ATC development project in Guatemala or Nicaragua. These challenges aim to create new appropriate technology designs to be tested in the Guatemalan context and shared open-source online for international use. Student Design Teams can include extra-curricular clubs or students registered for a semester course focusing on a topic related to appropriate technology, civil engineering, sustainable design, medicine, social sciences, etc. Student Design Teams research , build and test a particular appropriate technology prior to the final build in a known Guatemalan or Nicaraguan community. Prior and during the research phase of a project, the local Project Manager will maintain communication between the community and the student group to inform on community needs and appropriateness of design.
