Why is there no performance pay for kindergarten teachers?

Primary and secondary school teachers take "achievement" as a joke: if the school aims at "profit", it will have "achievement". If the so-called compulsory education administration is still implemented, wouldn't it be contrary to the commercialization of schools? Kindergarten should be the first ~ after all, it does not belong to the category of 9-year compulsory education ~ haha, I understand it blindly.
