We present the results of 2 studies, a citation-based study and an opinion-based study, that ranked the relative quality of 20 English-language journals that exclusively or extensively publish mathematics education research. We further disaggregate the opinion-based data to provide insights into variations in judgment of journal quality based on geographic location, journal affiliations and publishing records, and experience in the field. We also report factors that survey respondents indicated were important indicators of journal quality. Finally, we compare our results to previous related rankings and conclude by discussing how our results might inform authors, editors, and evaluators in their efforts to publish and recognize quality research in mathematics education.
