IELTS to CLB Conversion – Understanding Language Proficiency Requirements on Express Entry
In the interest of making it easier to understand and interpret, to their table I added the points per ability that were provided on the Canada Gazette posting mentioned above. Please Note: I have re-ordered the different abilities/modules to appear in the same order as they do on the Results Slip for IELTS exam

I also have assumed that any scores greater than those for CLB Level 8 will put you at CLB Level 9, as there are no scores on the table for Level 9.
