The Applied Public Health Informatics Competency Model was developed by the Informatics Academy at the Public Health Informatics Institute (PHII). It frames the knowledge, skills, and abilities that public health practitioners need to address the informatics challenges at their agencies. The target audience for this competency model is the general public health workforce across core functions of public health (e.g., epidemiology, biostatistics, behavioral health, environmental health). The framework encompasses informatics–related responsibilities across a health department, and it is not meant to be specific to informaticians or other staff whose primary responsibilities fall under informatics.
