Erasmus+ Project


The Erasmus+ project Diagnostic Tools in Mathematics (DiToM) brings together the expertise of international partners to develop a diagnostic screening instrument for assessing fundamental mathematical competencies (“mathematical key skills”). The aim is to provide teachers with a practice-oriented tool that enables them to reliably measure students’ competencies in arithmetic and algebra.
Within the project, five diagnostic tests were developed to be used at key transition points in the school trajectory—from school entry and after grades 2, 4, and 6 up to grade 8. The tests take into account competencies that are essential for learning mathematics. For each test, an evaluation sheet, a user manual, and printable test booklets are available. The materials were piloted in several iterative cycles and are made available free of charge for use in classrooms.
