Introduction Field Epidemiology Training Programs (FETPs) use a work-integrated learning model to equip graduates with skills in disease surveillance, outbreak response, data analysis, and evidence-based decision-making. The intermediate-level Field Epidemiology Training Program of Papua New Guinea (iFETPNG) was established in 2013 to strengthen the country’s public health workforce. This study presents the results of a theory-based evaluation of iFETPNG. Methods An FETP impact evaluation framework was used to guide data collection using a theory-based convergent mixed-methods design. Online surveys were administered to all 75 iFETPNG graduates from 2013 to 2019 (49 responded), and in-depth interviews were conducted with a purposeful selection of 20 graduates and 8 senior managers/executives from the provincial and national levels in PNG. Data were analyzed using Microsoft Excel, R, and NVivo. Results The evaluation found that iFETPNG substantially improved graduates’ skills in surveillance, outbreak response, operational research, and evidence-based public health practice. Since completing iFETPNG, graduates reported investigating 588 outbreaks, conducting numerous surveillance evaluations, and implementing a range of public health interventions. Individually and collectively, graduates helped strengthen public health systems in PNG. The program also supported the development of interpersonal skills, which built confidence and enhanced the leadership capabilities of graduates. Most graduates remained in the public health service and reported using the skills they acquired through iFETPNG in their current roles. Graduates reported professional advancement, with 32 (65%) of the 49 survey respondents reporting a promotion. Barriers to applying field epidemiology skills in the workplace included limited recognition and utilization of some graduates by senior management, resource constraints, time limitations, and professional jealousy. Enablers included strong graduate networks and supportive work environments. Recommendations include strengthening mentoring processes, providing ongoing training, and establishing clear career pathways for graduates. Discussion iFETPNG has made an important contribution to strengthening Papua New Guinea’s public health workforce and health system. Graduates have applied core field epidemiology skills to improve surveillance, outbreak response, and evidence-based decision-making. Embedding operational research and intervention implementation within a work-integrated training model has proven effective in a resource-constrained setting. Continued investment, strengthened mentoring, and formal recognition are critical to sustaining and expanding the program’s impact.
