The Aboriginal and Torres Strait Islander Mathematics Alliance (ATSIMA) is an Indigenous-led charity, registered and incorporated in 2015.

To achieve this vision, ATSIMA is creating new ways of teaching and learning mathematics by connecting to Aboriginal and Torres Strait Islander histories and cultures. By transforming mathematics education for Aboriginal and Torres Strait Islander learners - all students benefit.

The National Assessment Program Literacy and Numeracy (NAPLAN) and The Program for International Student Assessment (PISA) results continue to highlight the gap in mathematics learning outcomes of up to two years difference between Indigenous and non-Indigenous students. The Closing the Gap Report 2020, reported that in 2018 between 17-19% of Indigenous students were below the national minimum standards in numeracy. As a result, Indigenous people are significantly under represented both professionally and academically within STEM fields across Australia. ATSIMA is currently experiencing a period of growth due to a growing demand for support from schools and communities.
