FSW points vs CRS points
The FSW grid (out of 100, pass mark 67) decides whether you may enter the Express Entry pool as a federal skilled worker. CRS points (out of 1,200) then rank you inside the pool and decide invitations.
Minimum requirements
One year of continuous full-time skilled work (TEER 0–3) in the last 10 years, CLB 7 in every first-language ability, an Educational Credential Assessment for foreign degrees, and proof of funds unless you have a valid job offer.
