From 2000 – 2004, CDC’s Office of Public Health Genomics (OPHG) established and supported the ACCE Model Project, which developed the first publicly-available analytical process for evaluating scientific data on emerging genetic tests. The ACCE framework has guided or been adopted by various entities in the United States and worldwide for evaluating genetic tests; the CDC-supported EGAPP™ initiative builds on the ACCE model structure and experience.

Introduction to ACCE

ACCE, which takes its name from the four main criteria for evaluating a genetic test — analytic validity, clinical validity, clinical utility and associated ethical, legal and social implications — is a model process that includes collecting, evaluating, interpreting, and reporting data about DNA (and related) testing for disorders with a genetic component in a format that allows policy makers to have access to up-to-date and reliable information for decision making. The ACCE model process is composed of a standard set of 44 targeted questions (3) that address disorder, testing, and clinical scenarios, as well as analytic and clinical validity, clinical utility, and associated ethical, legal, and social issues.

An important by-product of the ACCE model process is the identification of gaps in knowledge that will help to define future research agendas. The ACCE approach builds on a methodology originally described by Wald and Cuckle (1) and on terminology introduced by the Secretary’s Advisory Committee on Genetic Testing (2).
