That's "Decision Made'. If you check ECAS, it is likely you'll see "Decision Made".I've just had my status of "Prohibitions" and "Physical presence" updated to completed.
My Language skills are "In Progress" with my Citizenship test showing "Not started" which is strange as I am exempt both because of my age.
At least there is some movement at long last.
Don't worry about the test status, it will either be set to "Waived" or "Completed" soon. Even if the status doesn't change for your test, it really doesn't matter because as it currently stands, your application has very likely been approved.
Wish you all the best!
