I do not believe you want to "speak plainly and avoid metaphor so we can understand and share knowledge.".
But if you do, please explain why apparently "At 13 Baltimore City high schools, zero students tested proficient on 2023 state math exam", even though they spend $22.424 per student and the median household income is $59,623.
To be clear, I do not for a moment believe it is because the majority of students are black and or poor.
