The Comprehensive Ranking System (CRS) score ranks candidates in Canada's Express Entry pool for immigration. Maximum CRS score: 1,200 points. Key factors: age (peaks at 20–29 years), education (PhD = highest), language ability (IELTS/CELPIP — CLB 9+ in all bands maximises points), Canadian work experience, job offer, and provincial nomination (adds 600 points). CRS cut-off scores vary — Federal Skilled Worker draws typically cut off between 480–540; Canadian Experience Class draws can be lower (420–480). How to improve: higher IELTS scores (each band increase adds significant points), Canadian job offer, provincial nomination, or Canadian education.
