Diagnosing a learning disorder (dyslexia, dyscalculia) is not always straightforward. We know this as well as the pupils affected, their families and their teachers.

The task is particularly complex in a context such as that of the Grand Duchy of Luxembourg: multilingual and multicultural. Furthermore, the limited number of standardised tests adapted to this specific context makes diagnosis even more difficult.

That is why we are actively involved in research in this field. In addition to collaborative projects with research institutes, we have had a research unit in place since the start of the 2025/2026 academic year. Its main role is to ensure consistent diagnostic and treatment processes, in particular through tools developed by the unit and made available to the entire team.

Collaborative projects with the University of Luxembourg

In collaboration with the University of Luxembourg, we have launched an ambitious project aimed at developing new tests, as well as adapting internationally recognised tests to the Luxembourg context and standardising them.

The first output of this project is a reference guide that analyses the current situation regarding standardised tests used in primary education and aims to facilitate their use by practitioners in the field (psychologists, educationalists, speech and language therapists, and psychomotor therapists). The guide also includes more practical sections, written in collaboration with specialists from the CDA, which outline a range of support measures for pupils.

Based on the findings of this analysis, a second phase of collaboration with the University of Luxembourg was launched. The standardised tests LuxLeseTest and LuxMatheTest were developed over a four-year period, before being officially launched in April 2025.
