The U.S. Department of Health and Human Services removed 9 research sessions—nearly one-fifth of the agenda—from the National Research Conference on Early Childhood less than a week before it begins, according to researchers whose panels were removed during the final HHS clearance. Presenters said the sessions were selected months earlier through peer review after proposals submitted last fall. Researchers reported receiving email notice on June 16 with only that “several revisions were required,” and said the revised agenda was posted the next day. The cancelled sessions cover topics including childcare licensing, kindergarten transitions, infant mental health, and social-emotional development. The cancellations have rattled conference participants from universities, nonprofits, and government agencies, raising questions about how clearance processes affect scholarly dissemination and policy-relevant evidence-sharing in early childhood education.
