Key legal question
Whether the Passerelle tuition costs had to be covered as additional costs of first vocational training, retraining, or further training under IV law.
Extracted holding
The tuition costs were not payable as invalidity-related additional costs; the Passerelle was treated as further training, but it did not create compensable extra costs beyond those of non-disabled classmates.
Extracted reasoning
The course led to a new academic path outside the commercial field and was not part of the original commercial training. Even under the correct further-training concept, IV only covers invalidity-related extra costs; ordinary tuition fees are not such extra costs.
