This handbook describes the history, objectives and operations of the Resource Development Internship Project (RDIP), a project designed to simultaneously strengthen the educational process and increase the number of skilled personnel working on development problems by placing upper division and graduate students--students who already have the basic package of usable technical skills--as interns in operating organizations. While it is intended primarily to provide information for interns and host organizations participating in or considering RDIP-approved projects, this handbook may also be useful as a general guide for organizing effective professional and administrative internships under a wide variety of circumstances.
