Looks like you´re talking about the old´german "myth", that says "get a Junior Degree AND an apprenticeship=that equals the Matura/Abitur"....
In fact, this is not true...
What it is all about (as far as i understand it), is that when you have both, you CAN go to university and get a degree (in special subjects AND only in some countries).
For that, you should contact the "Bildungsministerium" (Ministry of Education) in your german country-they should be able to give you a letter of qualification.
Then you only need to have this translated into english-et voilá!
