Journal of Mixed Methods Research (JMMR) we are excited with the growing number of scholars around the world who are conducting highly innovative mixed methods studies and submitting their innovative mixed methods work to the journal. With the growth in interest, we have seen an increase among authors new to the journal who are less familiar with the elements that constitute a compelling mixed methods study. We appreciate and applaud the highly thoughtful and innovative ideas from the current mixed methods researchers community. Herein, our purpose is to provide transparency about elements in articles that we believe help advance the methodology of mixed methods research, and guidance to those new to the mixed methods research community through the use of a checklist. JMMR is a methodological journal and all articles must add value and contribute to the advancement of mixed methods research methodology. Therefore, all articles are methodological papers, as they must emphasize methodological characteristics and highlight the contribution to the latest mixed methods literature. In this editorial, we present a checklist of methodology elements for inclusion for both empirical methodological mixed methods research articles and methodological/theoretical articles that are submitted for consideration of publication in JMMR. We hope that these elements may also be helpful for authors submitting mixed methods methodological manuscripts as chapters for inclusion in handbooks or other methods-focused journals. This checklist is not a rigid standard or requirement for authors to use, but recommended elements for inclusion that we have found through experience to best present a methodological contribution to the mixed methods literature. We anticipate that this checklist will primarily benefit those new to JMMR. In the following, we review the major categories of articles accepted at JMMR, we introduce the rationale for a checklist advancing the methodology of mixed methods research, and provide a
