Engineers Australia Skill Assessment

Dear Anil,

I have a positive skilled assesment from Engineers Australia upto my previous employer which counts for 4 years 10 months and unfortunately I had to change my employer.
Please guide, Do I need a new skilled assessment to include new employer to complete 5 years and claim 10 points or my current skilled assessment with 4 years and 10 months is enough and for the remaining months can i provide experience letters and pay slips.

If I have to do new skilled assessment, do i need a IELTS 6 bands ?

Thank you.
