Why Writing holds back your CLB 9 (and your CRS points)
Express Entry's CLB mapping is per-skill: Reading 8, Writing 7, Listening 8, Speaking 7 — that's CLB 9, worth 31 points per language ability with a spouse (or 34 without) versus the 29/32 at CLB 8. Many candidates clear 7+ in speaking and listening but stall at Writing 6.5, stuck one band below the threshold that actually moves CRS scores.
Writing is the skill most candidates self-study wrong, because the band descriptors are public and people still write essays nobody scores. This guide gives you the structure examiners reward, and you can get your essay scored with estimates on this site's writing practice page.
