Direct points: yes, immediately
Each CELPIP skill contributes its own CRS points independently. If your Speaking is CLB 7 and everything else is CLB 9, raising Speaking from CLB 7 to CLB 9 adds +14 direct CRS points (31 − 17 = 14 per skill) for Speaking alone.
Transferability: uses your minimum CLB
Transferability bonuses are based on your lowest CLB score across all four skills. If one skill is below CLB 9, you don't get the CLB 9 transferability rate — even if the other three are at CLB 10. Raising your weakest skill to CLB 9 can unlock significantly more CRS than the direct points suggest.
Strategy: raise your lowest score first
If you're at CLB 9 in three skills but CLB 7 in one, fixing that weakest module should be your highest priority. You gain direct points AND unlock the CLB 9 transferability threshold for all your other combinations. It's the highest ROI move in Express Entry prep.
