About CLSI


Consensus Council

This body, composed of selected volunteers, provides holistic process oversight of all documents developed through the CLSI consensus process.

The Consensus Council is the authority over all CLSI standards development activities, including project approval, prioritization, status assessment, and consensus approval for document publication. The Consensus Council serves as the consensus body for CLSI, and ensures that CLSI’s standards development activities are in alignment with Board-directed organizational priorities, CLSI’s mission and vision, budget, and resource availability.


  • Tentatively approves project proposals, including the proposed chairholder (and vice-chairholder, if known), before the Call for Volunteers for the project

  • Actions as the liasion, as needed, with the Expert Panels for technical reviews or advice on technical matters
