External Panelists

Proposals reviewed by the External panels are subject to a one-stage review process.

External panelists will read, grade, and provide feedback comments for all proposals that they are assigned. There is no discussion meeting for this part of the review process.

Before getting started, familiarise yourself with the review process, Hubble and its instruments, the types of proposals you will be reviewing, and who to ask for help!

During this phase, you will:

  • Read a subset of the proposals assigned to your panel (each proposal is assigned 5 reviewers).
  • Enter numerical scores as grades for each proposal you are assigned.
  • Write brief comments (strengths and weaknesses) for each proposal you are assigned.

Please remember to remove review materials from your computer after the review.
