She should have her work supporting documents the same as the noc code that she will select so for example she cant have her work experience letter as a dental assiatnt while choosing her noc code as a dentist,they should match, as for the requirements for the letter it should mention her duties,title,job description,no of hours,annual salary,duration of work and be on a letter head with signature of supervisor,you will find a lot of threads with more info on the forumsThanks a lot for clarification.. Her score as of now is around 398 but I think if she will reappear in IELTS it can be improved..
What kind of supporting should we have get for paid internship? And also when adding that as experience, what should we select as title? I think it should be Dental assistant as that time she was just assisting her seniors..
