Special Needs

Today, an increasing number of children struggle to keep up with the traditional educational system. The learning methods have not evolved in years and no longer meet the needs of children facing difficulties.

Currently, about 25% of the population has a learning disorder. These disorders can be visible or invisible, making their diagnosis difficult.

Whether your child suffers from dyslexia, dyspraxia, dyscalculia, dysgraphia, or giftedness, methods exist to help the child progress in their learning. Support for the child should not be limited to external interventions outside the school. The entire teaching team will work closely with specialists who support the child to develop a personalised educational plan.

Children spend about 8 hours a day at school, 5 days a week. School is where children spend the most time during their first 15 years. It is absolutely necessary for children to feel good, valued, encouraged, and supported in their difficulties.
