»Students who used system between 2014 and 2016 had 10% better learning outcomes in maths than those who did not. 30% increase for students within lower social economic environments.«

Over 500 schools in Germany are working with bettermarks. In 2009, the Transfer Center for Neuroscience and Learning (ZNL) at the University of Ulm made a study to evaluate efficacy:

In the Netherlands, digitalisation has progressed considerably. Students are working in average over 90 minutes per week with bettermarks:

»With a significance of 99.8%, students with more intense usage (more than 10 exercise series in a topic) achieve on average at least 12% better results in a post-test than students with lower intense usage (3 or less exercise series in a topic). Performance gap between higher and lower level is reduced.«
