Membership in the Washington University Law Review is limited to second- and third-year law students. The only way to obtain membership is to participate in the Write-On Competition, which is open to all transfer and first-year Washington University Law School students. Members are selected based on their legal writing and editing skills. The Law Review selects roughly fifty editors each year.

Editors invited to join the Law Review join as Staff Editors. Throughout their first year on the Law Review, Staff Editors are responsible for editing legal scholarship selected for publication. These edits involve conducting substantive edits, proofreading text above-the-line and below-the-line, and checking Bluebook citations. Staff Editors are also responsible for composing a note of publishable quality on a topic of their choice, which may be published in the Law Review. In their second year, Editors can maintain the same editing responsibilities as Senior Editors, or can apply to serve on the Law Review’s Executive Board.
