PurposeThe paper aims to present what is known from the school principals who participated in the International Successful School Principalship Project (ISSPP) in Mexico. The paper reviews 14 publications (5 articles, 5 conference papers and 4 books) on successful school principals in Mexico that were published between 2009 and 2021 as part of the ISSPP. The papers were analysed using a conceptual framework consisting of perceived qualities of the principal, school organisation, suitability of teachers and principals, educational materials and methods and educational infrastructure.Design/methodology/approachA scoping study review methodology was used to explore publications and conference proceedings on ISSPP research on Mexican principals and schools in order to answer the question: What do we know about successful school principals in the Mexican context? Conference papers, journal articles, book chapters and books formed the knowledge base for the review.FindingsAs a result of the analysis across the five analysis categories it was found that the principals emphasised improving the educational quality of their schools and understood this as the basic criterion to judge their leadership success. Principals were central to school success and a nested model was produced to show how the successful school is built from the core of the principal, as a socio-emotional skills role model, to a culture of continuous improvement. The model included principal socio-emotional skills, school organisation, continuous improvement of teaching and principal practices and having appropriate educational materials, methods and infrastructure.Originality/valueThe ISSPP has produced a large amount of research. The paper is the first review of the substantial contribution from ISSPP research in Mexico. The model produced from the review adds to the several models produced in the ISSPP.
