Translation:The advanced training takes at least seven years.
The are a lot of variations of this sentence that aren't accepted and should be.
"The advanced training lasts for at least seven years."
"The continuing education lasts for at least seven years."
I've reported both. I think that the curators need to review the options available.
In a previous exercise "advanced training" was not accepted for "Weiterbildung".
I entered this translation exactly as above and it was not accepted (because training has been mis-spelt).
Please correct it Duolingo!
