The content of an apprenticeship is defined on a higher level and not by technology. So it doesn't really matter what kind of technology the company uses. Examples would be: Can read&write a spec, can develop a program based on a spec and so on. The more theoretical part is usually done in school wich all apprentice from the different companies attend.
It has changed a lot how this is organized in the last 10 years so I`m not really up to date anymore. I think currently besides weekly school the apprentice will go to multiple week long sessions at the school where all the fundamental things will be thought. But besides that the rest needs to be done by the employer.
