Hi,
For your wife, For the moment it seems that she will get Level - 7.
Can't say anything about your qualification. Just apply for the IQA and keep your fingers and toes crossed :-)
One thing more, If you will manage to get even Level-8 for your qualification, you will still get through bcz you have 6 years of experience in an AASS. I think you will end up with minimum 140 points. Have you calculated your points yet ? If yes then can you mention them here for the members to check and confirm ?
Note : In order to claim points for your wife's qualification, she must have IELTS minimum 6.5 overall.
Regards,
