Research & Evaluation

PHAB is committed to evaluation as part of its own quality improvement.

PHAB also encourages research to develop the science base for accreditation and systems change in public health.

Logic Model

To help guide research and evaluation efforts related to accreditation, the PHAB Research and Evaluation Committee developed a logic model. The logic model was revised by the Evaluation and Quality Improvement Committee and the Research Advisory Council and approved by the PHAB Board of Directors in June 2017.

Research Agenda

In June 2017, PHAB released a revised research agenda to identify questions that could help strengthen the evidence base around accreditation.

Accreditation is also referenced in the National Research Agenda for Public Health Services and Systems.

Accreditation Data

To honor its commitment to building the evidence base for accreditation, PHAB will release data generated through the accreditation process to be used for research purposes only. PHAB remains committed to respecting the confidentiality of health departments that apply for accreditation.

Before requesting data, researchers should review the documents below. If you have any questions, please contact Jessica Kronstadt, Director of Research and Evaluation (

Accreditation Research

PHAB has assembled a list of publications and reports relevant to accreditation.

Publications and Reports about Accreditation


In addition to conducting internal evaluation activities, PHAB had a contract with an external evaluator to gain an understanding of the accreditation program’s strengths, opportunities for improvement, and impacts.  Data collection for that evaluation is ongoing. PHAB uses evaluation findings to continuously improve the accreditation program.

For evaluation findings from applicant and accredited health departments, read the report or download a presentation that highlights key findings.

Evaluation Metrics

PHAB is developing a series of documents highlighting key benefits of accreditation. Each will contain a Researcher Addendum, which describes data that are currently being collected that can increase our understanding of the link between accreditation and a specified topic as well as some examples where instruments have been developed that can measure this topic, but where there is no current effort to collect data on a national basis.

MMWR Reports Evaluates the Impact of PHAB Accreditation

A report in the August 12, 2016 issue of Morbidity and Mortality Weekly Report (MMWR) describes how the national public health department accreditation program launched by the Public Health Accreditation Board (PHAB) in 2011 is bringing far-reaching benefits to health departments and the communities they serve. The report, “Evaluating the Impact of National Public Health Department Accreditation — United States, 2016,” draws from surveys conducted by a social science research organization to describe the many benefits accreditation brings to health departments and communities, including fostering engagement in quality improvement, enhancing management processes, and improving accountability.
