Do You Work in Disease Intervention?
You are key to strengthening the disease intervention workforce.
Certified in Disease Intervention (CDI) Program
Disease intervention (DI) professionals are vital members of the national public health workforce, reducing community spread of infectious diseases through activities such as contact tracing, partner services, health education, and facilitating access to care. Certification is intended to strengthen the DI workforce by establishing and validating professional competencies and supporting consistent, high-quality disease intervention services. Additionally, certification will allow employers and other workforce partners to easily identify individuals who have demonstrated relevant DI professional competencies.
Through a cooperative agreement with the Centers for Disease Control and Prevention (CDC) supporting the National Disease Intervention Certification Project, the Association of Schools and Programs of Public Health (ASPPH) has been funded to develop and implement the CDI Program and the infrastructure in which it can succeed. The CDI Program aims to:
- Standardize and validate knowledge, skills, and abilities of disease intervention professionals, increase quality and consistency of service delivery, support the recruitment and retention of a diverse disease intervention workforce.
- Recruit, train, and retain the disease intervention workforce and strengthen pathways from educational institutions to the disease intervention workforce and CDI Certification.
ASPPH partnered, through a subaward, with the National Board of Public Health Examiners (NBPHE) to serve as the CDI Certification provider. NBPHE’s certification work supports the development of national practice standards and informs core competencies for the disease intervention workforce.

Disease Intervention Job Task Analysis
A key step in developing the CDI program is the job task analysis (JTA), which systematically identifies the responsibilities associated with a particular job or role within an organization to inform certification examination development. The Disease Intervention JTA was designed to better understand the work performed by disease intervention professionals, including which tasks they perform most frequently and which they consider most important to their work. The findings can also provide employers, academic institutions, training programs, and others with greater insight into the roles and responsibilities of the disease intervention workforce and its training and professional development needs.
The 2026 Disease Intervention Job Task Analysis Survey was administered from May 15, 2026, to July 31, 2026.
Survey responses are being analyzed to inform the continued development of the CDI Program, including updates to the certification examination content outline, study preparation resources, and disease intervention workforce training needs.

Academic and Practice Partnerships
ASPPH collaborates with academic institutions, national public health practice partners, public health agencies, educators, and workforce leaders to support CDC’s National Disease Intervention (DI) Certification Project and advance public health initiatives and professional training. Academic partners specifically include CEPH-accredited, ASPPH-member schools and programs of public health or institutional members of the ASPPH Undergraduate Network for Academic Public Health.
