What the research actually shows.

Scientists from some of the world's top universities have studied what happens to children who go through UCMAS training. The findings are remarkable — and they are written in plain language below, so every parent can understand them.

UCMAS Harvard-Stanford-UCSD Research

A landmark collaborative study examining the cognitive benefits of abacus-based mental arithmetic training on children's intellectual development.

How many numbers can your child hold in their head at once?
UCMAS children can hold up to 4 times more numbers in their head at once — compared to children with no training.
This is called working memory — the mental space your brain uses to process information. The more space you have, the faster and better you think.

What this means for your child: A bigger mental workspace means faster problem solving, better reading comprehension, and stronger performance across all school subjects — not just mathematics.

Does abacus training actually make children smarter over time?
Intelligence scores rose by 12 points over 42 years — a rise directly linked to structured abacus training programmes.
This was a nationwide study in Sudan tracking how intelligence scores changed as more children enrolled in abacus-based training. The improvement was consistent across every decade measured.

What this means for your child:Intelligence is not fixed at birth. With the right structured training during the right age window, a child's cognitive ability measurably increases — and UCMAS children in this study showed exactly that.

Do UCMAS children perform better in school mathematics?
UCMAS children scored nearly 9 points higher in mathematics tests — compared to children who had no abacus training.
This was a study of 144 children where scientists also scanned their brains using special imaging technology. The UCMAS children not only scored higher — their brains were also working more efficiently.

UCMAS children's brains used less effort to solve harder problems
What this means for your child: UCMAS children do not just get better at maths — their brains literally rewire to become more efficient. They solve harder problems using less mental effort, leaving more brainpower available for everything else.

By how much does UCMAS training improve a child's memory?
UCMAS children can remember more than twice as many numbers in a row — a skill that transfers directly to reading, science, and problem solving.
Researchers tested how many numbers in a sequence a child could hold in their short-term memory. This ability — called digit span — is one of the most reliable measures of overall memory strength.
