As the submitted article here notes,
"Of course, finding qualified teachers to teach advanced maths courses will not be easy."
Not easy by far. Here is a detailed article about just how difficult it is to find elementary school teachers who know even very basic math

and how especially lacking such teachers are in school districts with mostly poor students from ethnic minorities. One finding from that article illustrates the grave nature of the problem:
"in my first visit in 1986 to a K-6 elementary school, I discovered that not a single teacher knew how to find the area of a rectangle."
