Our impact
Tassomai makes a difference!
Tassomai is raising attainment in GCSE science, maths, English, history, geography, computer science and other subjects. The program is used by private subscribing families and more than 300,000 students in 500+ schools across England and Wales.
Tassomai is changing the way students learn, and enabling teachers to spend less time on marking and more time teaching.
”Tassomai has had an incredible impact on the progress of our students and has helped to plug the knowledge gap due to COVID.“
- David Gash, Head of Science, Gateacre School
Hear from teachers, students and parents about the impact Tassomai has on teaching, learning and grades.
Let’s celebrate...Tassomai’s Class of 2025
Over the 24/25 academic year Tassomai was used in schools for up to 6 different subjects. We were also delighted to have rolled out new features to support pupil premium students and to bring Tassomai into the classroom.
Congratulations to all of our hard-working students, particularly those taking exams. We hope all those questions answered, videos watched and Daily Goals completed help you to get your best possible grades!
“We have now subscribed to Tassomai for several years and have seen such a dramatic difference in our pupils that our GCSE results last year were some of the best we have ever had, and as such we are really looking forward to continuing to work with you.”
- Holly Bradshaw, science teacher, Marple Hall School, Stockport
The more a student uses Tassomai the better their results
Tassomai conducted its first mass data study in 2017, taking in over 68,000 examination module results from Tassomai-using schools, cross-referencing with their students’ course progress statistics and measuring the impact on outcomes.
The data showed exceptionally high correlation between Tassomai usage and attainment, with 90% of strong users achieving a strong pass or better (vs. 68% nationally) and 50% achieving a top grade.
”Our internal statistics consistently show that pupils who are fully engaged with the program have a 92% chance of meeting their targets.“
- James Stradling, Head of Science, All Saints, Dorset
"Students always say "Miss, do you know how I remembered that… Tassomai!”
- Amy Hill, Deputy Head of Science, Frogmore Community College
Tassomai helps schools to close the attainment gap
A second major data study was undertaken in the academic year 2018/2019, to look at Tassomai’s impact on student progress with a large-scale pre & post trial.
Knowledge and recall was tested in the app at the start of the academic year, and again at the end of the year. The change in attainment was cross-referenced with engagement in the Tassomai program, and the cohort was stratified by their initial performance into a lower-attaining and higher-attaining group.
The cohort was a randomised sample of 1500 students of all abilities distributed around the UK in various school settings.
The research showed that students of all abilities improved in their knowledge recall with Tassomai, and that this improvement increased with increased use of the software.
Further to this, the effect on students of lower initial abilities was more marked - a fact that has far-reaching implications for schools seeking to close their attainment gap in STEM subjects.
Helping teachers to spend their time teaching, not marking!
Used as a homework tool and lesson starter, Tassomai reduces time spent on the setting and marking of formative assessment, and on the collation of data for the purpose of planning intervention.
Teachers at St. John Bosco College estimated that Tassomai saved each GCSE classroom teacher 2 hours per week per class - time that is deployed more usefully into supporting students with their studies.
In addition, the use of Tassomai to cover staff absence, or to inform cover teachers of student needs presents a considerable saving in cover budget and resources.

“The reduction in marking has been notable… Tassomai essentially allows us to have more learning time both within and outside of lesson and results in fewer admin and paperwork tasks.”
- Laura Foulsham, Head of Science, St. John Bosco College
Tassomai is leading the way in award-winning, evidence-based EdTech!
We believe companies involved in education have a responsibility to measure their impact. That’s why we have always been advocates for evidence-based edtech, co-founding the EdTech Evidence Group and participating in UCL’s EDUCATE programme where we earned the prestigious Evidence Applied badge.
It’s always great to get some recognition, and in the Spring of 2025 we were delighted to be named number 1 in Business Cloud Magazine’s annual EdTech50!
This annual ranking celebrates the UK’s most innovative startups, scaleups and established firms creating original technology for education and workplace development. The EdTech50 is decided by a combination of public vote and judges recommendations.
In 2024, the Tassomai team were delighted to be ranked number 3 in the EdTech 50. Since then we’ve continued to innovate and develop the platform and this year’s number 1 placing is testament to the hard work of the team over the last year.
We are proud to have been Bett Awards finalists in multiple categories since 2018, and to win the Bett Award for “Best Educational Resource for Parents and Home learning” in 2019.
The Bett judging panel said:
“This revision resource is laser focused on helping learners prioritise through adaptive learning.”
Tassomai was shortlisted in the Secondary Resource and Company of the Year categories for 2025’s Education Resource Awards.
In 2023 Tassomai won an Education Resource Award in the “Secondary Resource - Tools for Leadership, Management and Assessment” category.
In 2021 Tassomai were proud winners of two ERAs: “Supplier of the Year” and “Best Collaboration with a School” for our content partnership with Torquay Academy.
Tassomai is also highly rated by teachers on independent, external review platforms…

Tassomai’s GCSE Survival Guide is a practical handbook for parents of students in years 9-11. (We also have a version for students.)
“My son has special educational needs and receives 1-2-1 support throughout the day in school. By continuing the use of Tassomai last summer holidays he was able to retain knowledge learnt so did not regress during the long break. Little and often. It works. Thank you."
Dawn, parent
