The CHW AIM (Community Health Worker Assessment and Improvement Matrix) is a tool that assesses CHW program functionality, aids in improving performance, and provides action planning recommendations. It was tested in Zambia through a participatory workshop involving 5 organizations. Two organizations showed overall improvement in functionality after implementing interventions identified. A positive correlation was found between functionality and CHW performance, but a weak correlation with engagement factors like opportunities for advancement. The cost per participant was $16.91-$56 and cost per client served was $0.41-$3.11, showing potential for cost-effectiveness. Recommendations focus on investment, technical assistance, expectations, prioritization, facilitation, leadership support, and country ownership
