If you are studying a language, it’s likely you will need to know what the next step is when you complete you course. Given that there are many different methods of learning, it seems useful to compile the handy reference table below of how some of the more common courses relate to each. Luckily there is a benchmark that most of the courses share and reference to allow this comparison, called the Common European Framework of Reference for Languages (CEFR) although it’s nice to have it all in once place.
|CEFR||ACTFL *||UK Exams||Language
|A1||Novice (Low/Medium/High)||Breakthrough 1-3||Stage 1-3||Entry Level||Start Deutsch 1||Level 1||Level 1|

To answer the original question, specifically in relation to Rosetta Stone, i found the following information on their UK website.
Rosetta Stone and the Common European Framework for Languages (CEFR)
The content and design of Rosetta Course™ Levels 1 and 2 provide the setting for learners to produce most of the skills associated with the CEFR A1 and A2 designations.
At the completion of Level 5 of Rosetta Course™, learners have been exposed to a variety of content that should enable them to reach into, but not necessarily master, the B1 level of proficiency. With further exposure to new grammatical forms and vocabulary, learners should become more comfortable being exposed to media, ad hoc conversations, and interpersonal correspondence in their language of study
