The American Journal of Evaluation (AJE) publishes original papers about the methods, theory, and practice of evaluation. The general goal of AJE is to present the best work in and about evaluation, in order to improve the knowledge base and practice of its readers. Because the field of evaluation is diverse, with different intellectual traditions, approaches to practice, and domains of application, the papers published in AJE will reflect this diversity. Nevertheless, preference is given to papers that are likely to be of interest to a wide range of evaluators and that are written to be accessible to most readers.
