The pages dealing with the JWST Peer Review Information, for which the hierarchy is shown in the left sidebar and below, describe the process by which JWST proposals undergo peer review. This process is coordinated by the Science Policy Division (SPD) at STScI. The SPD is home to the scientific and technical staff that manages the allocation of research funding and observing time on the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST). 

For JWST, the SPD is responsible for maintaining the process of selecting the science program for General Observations (GO), Surveys, and Archival Research (AR) in response to the current JWST Call for Proposals. The SPD also facilitates the review of Director's Discretionary (DD) time proposals; those proposals and their review process are described in the current cycle's JWST Director's Discretionary (DD) Time Proposals page. The SPD is the point-of-contact between the James Webb Space Telescope Users Committee (JSTUC) and the leadership at Space Telescope Science Institute (STScI).

The SPD's key objective is to optimize and maximize the scientific productivity of JWST. The SPD fosters the submission of the highest quality scientific programs, including working with the community to identify key scientific areas for the investment of JWST observing time, and encouraging broad multidisciplinary and multi-observatory collaborations.
