special school

The skolebehandlingstilbud is an arrangement - probably a day-school in contrast to 'bosteder', which are residential, where children or young people with special needs are catered for. You don't say what kind of problems they suffer from - they may be developmental, social or both in a skolebehandlingstilbud.

This is just one example, if you look through all the 'pages' in the link.

Very often the 'tilbud' in these social contexts (plejetilbud, behandlingstilbud etc.) just means a place or a scheme - and there is no real option of turning it down!

Hope that gives you a clue
