The 15th International Conference on Multilevel Analysis will be held on April 14–15, 2026, in Utrecht, the Netherlands. The conference focuses on all aspects of statistical multilevel analysis, including innovative applications, theory, software, and methodology, and is organized in an informal format with ample room for discussion. The venue is located in Utrecht’s city centre, within a 15-minute walk or a 5-minute bus ride from Central Station.

Keynote speakers include Prof. Dr. Donald Hedeker, who will speak on multilevel methods for intensive longitudinal data, and Prof. Dr. Paul Bürkner, who will present on amortized Bayesian inference.

The call for abstracts is now open for talks on statistical or methodological aspects of multilevel modelling, advanced applications, or tutorial-style presentations. The submission deadline is 23 February 2026. Poster submissions are reviewed on a rolling basis.

Two workshops will be offered: a pre-conference workshop by Prof. Hedeker on modelling intensive longitudinal data, and a post-conference workshop by Prof. Bürkner on Bayesian multilevel modelling using brms.
