The Proceedings of the Fourteenth International Group for Mathematical Creativity and Giftedness (igMCG) Conference encapsulate the collaborative and scholarly efforts of researchers and practitioners in the field of mathematical giftedness. Held in Karlstad, Sweden, in partnership with the European Council for High Ability (ECHA), this joint conference allowed attendees to customize their experience by accessing sessions from both organizations. Four keynote speakers — Kirsi Tirri, Jan Kwietniewski, Jorryt van Bommel, and Tracy Reileym — shared diverse insights, with van Bommel’s full keynote included in the proceedings due to its specific focus on mathematicalgiftedness. 

The igMCG maintained its tradition of requiring full papers, distinguishing its contributions from ECHA’s abstract-based submissions. As a result, this volume includes only full texts from igMCG participants, in addition to keynote materials. 

The editorial team, led by Chair Elisabet Mellroth, expressed deep gratitude to contributors, reviewers, and organizing partners. Special thanks were given to Karlstad University, the City of Karlstad, Professor Valerie Margrain, and the Conference Department of Karlstad University for their crucial support. The editorial board’s dedicated work, along with the reviewers’ thoughtful assessments, ensured high academic standards and meaningful content. 

This conference introduced a new presentation type — short communications — widely used in Sweden, allowing presenters to share early-stage or design-focused research. In total, 41 submissions were received across various formats: 18 full papers, 13 short communications, 7 workshops, and 3 posters. All submissions underwent an open peer-review process, with feedback used to determine acceptance and guide revisions. Ultimately, 15 papers, 11 short communications, 7 workshops, and 4 posters were accepted, though some could not be included in the proceedings due to unforeseen global circumstances in 2025. The conference marked a milestone as the first igMCG conference hosted in Sweden and emphasized inclusivity, collaboration, and academic rigor in gifted education.
