Adverse childhood experiences (ACEs) are potentially stressful or traumatic incidents that harm social, cognitive, and emotional functioning and undermine the safe, stable, nurturing relationships and environments children need to thrive. ASTHO works with state, territorial, and freely associated state health agency leadership, their staff, and cross-sector partners to strengthen jurisdiction-level infrastructure to elevate ACEs prevention. ASTHO also aims to increase knowledge and inspire ACEs programmatic, legislative, and leadership staff to establish policies upstream. See ASTHO's ACEs prevention webpages on policy, partnerships, and data to learn more.

Collaborations
Through the ACEs Learning Community, ASTHO collaborates with state health agencies and other public health organizations to examine national trends in ACEs prevention priorities, strengths, and areas of improvement. ASTHO also closely coordinates with Safe States Alliance to support the ACEs Learning Community activities and products.
As a result of participating in the learning community, states have increased their capacity in the following ways:
- Mapping and surveying ACEs partners and sharing data with external ACEs partners.
- Fostering cross-sector dialogue and strengthening connections within the state.
- Deepening understanding of the existing knowledge, work, and capacity around ACEs within a state.
- Bolstering state health agencies as ACEs experts.
- Understanding the scope of relevant ACEs policies.
- Identifying strategies for coalition building and policy change.
- Finding braiding and layering opportunities within their agency.
