LEPAC consists of 15 Federal and non-Federal experts in the fields of epidemiology, toxicology, mental health, pediatrics, early childhood education, special education, diet and nutrition, and environmental health. Half of the committee (8 people) consists of Federal representatives. The Centers for Disease Control and Prevention (CDC) solicited federal members from HHS, the Consumer Product Safety Commission (CPSC), Department of Agriculture, Department of Education, Department of Housing and Urban Development, Environmental Protection Agency (EPA), Occupational Safety and Health Administration (OSHA), and U.S. Geological Survey.

A Federal Register Notice to solicit nominations for non-Federal members was published on February 21, 2018.
