Most graphs of the fertility rate depict the 'period fertility rate', which is based on a single year's data and doesn't necessarily reflect how many children women actually have across their lifetimes.
I've used data from the Human Fertility Database to show the cumulative number instead:

There's a narrative that because the bivariate correlation between education spending and student test scores is small/null, education spending doesn't matter.
