What CLB 8 already clears
FSW's language floor is CLB 7, and CEC floors depend on the TEER category, so a four-skill CLB 8 profile satisfies many program minimums. Minimums are not the same as competitiveness: check what your target stream actually draws at.
What one more point buys
Moving one ability from CLB 8 to CLB 9 adds 8 core points, and moving all four unlocks maximum skill-transferability factors. That combination is why the 8-to-9 retake is so often worth planning deliberately.
