Evidence and Impact
Sumdog is committed to closing the attainment gap through targeted, personalised practice that children genuinely enjoy. By combining engaging, game-based activities with powerful adaptive technology, we help every child, regardless of starting point or background, build confidence, fluency, and a positive attitude towards learning.
To make sure we are truly making a difference, it’s extremely important that we regularly conduct independent, external research. This allows us to rigorously evaluate the effectiveness of Sumdog in real classrooms, understand the impact of regular practice on pupils’ progress, and ensure our approach remains evidence-informed.
