What is the equivalent of year 9 class to french class?

There isn't a direct equivalent of "Year 9" in the French school system because the systems are structured differently. Year 9 is typically the third year of secondary school in many countries, including the UK and Australia.

In France, the equivalent would be troisième (3ème), which is the last year of *collège* (middle school). Students then move on to *lycée* (high school). The level of French language instruction in 3ème would roughly correspond to the level of French taught in Year 9, though the specific curriculum will vary.
