For two decades, the International Conference on Evaluation and Assessment in Software Engineering (EASE) has become the premier event of Empirical Software Engineering and Evidence-Based Software Engineering. The EASE conferences offer an international forum where empirical researchers and practitioners can present their latest work, and where issues related to all forms of empirical research and evaluation in software practice can be discussed. In 2016, the 20th EASE conference will take place in Limerick, Ireland. Following the EASE tradition, we continue to invite submissions on any aspect of evaluation and assessment covering a wide range of topics in software engineering.
