With a social work degree, you can get an accreditation to work in childcare but not 'kindergarten' - but you could work with older children in 'after-school care'..
Have you had your qualifications recognised by CRUS (swiss council of universities) ? That's the first step to getting your qualifications approved. They have to first assess your degree (there may be a precedent, depending on your degree/course and university)...
If it makes you feel any better, my colleague just got her social work degree from Germany approved in Switzerland, and she had to provide her qualifications, a dossier, 2000 word application decribing her 'fitness' to be a social worker in the swiss system, a 10 minute video of herself presenting a social work concept, references, and a 5 hour interviewing process where she was the only candidate....and she's a native high-german speaker
It was approved...without any 'problems'...just a lot of hoops to jump through...
