Your accreditation is valid for four years. The work placement advisor from SBB can extend the four-year period. In specific circumstances, he can also withdraw the certification.
Before the period of four years comes to an end, SBB will assess accreditation once again. To this end, please contact your work placement advisor. If he provides a positive recommendation, you will receive email confirmation. This extension is also valid for four years. If the advisor does not extend the accreditation, he will notify you in writing and provide his justification.
The work placement advisor can decide, at any moment, to withdraw your accreditation. He will do so if your company no longer fulfils the conditions for accreditation or other serious issues that are detrimental to the interests of the student. If he decides to do so, he will notify you in writing and provide justification.
