The Institute for Public Health Innovation, in partnership with the National Network of Public Health Institutes, offered a training series on effective training development. Throughout five sessions, which took place from late May to June 2022, the training series enabled public health professionals to apply the CDC Quality Training Standards in developing, delivering, and revising trainings to ensure they meet fundamental standards for quality. These standards are broad enough to cover any training topic and format, including virtual or in-person. The series was designed for public health professionals, including instructional designers, workforce development specialists, training developers, and others who have previous trainings to develop or improve.
