AAAS Science & Technology Policy Fellowships offers fellowships in all three branches of the federal government. The Roger Revelle Fellowship in Global Stewardship focuses on environmental initiatives and is offered periodically (not annually).
You may apply for up to two fellowship opportunities through AAAS. AAAS sponsors more than 150 placements in the executive branch, two legislative placements and one judicial placement. In addition, roughly 30 additional placements in the legislative branch are available through the Congressional Science & Engineering Fellowships. If you are interested in a legislative branch fellowship, you are encouraged to apply to AAAS plus any partner society.
