Your qualifications - whether a degree or job experience from your home country - need to be recognised in Germany before you start job hunting. Find out more about the recognition of foreign certificates in the chapter "Certified copies". If you do not have a formal degree but have extensive experience in a profession, you can have your qualifications checked. You will find qualification tests in English for various jobs at www.meine-berufserfahrung.de.
These tests reveal where you stand professionally. You can take your test result to the Jobcentre and do another longer, more comprehensive test (in German, English, Arabic, Farsi, Turkish, French and Russian) at www.myskills.de. This second test enables the Jobcentre and potential employers to better assess your skills and experience and helps you find a job that matches your qualifications. You can also start advanced training ("Weiterbildung") based on your current knowledge and skills. You can seek advice from the Job centre or the Employment Agency.
