The pursuit of educational equity plays a pivotal role in cultivating societal parity. This study aims to evaluate the patterns and inequalities in the mean per-student educational spending in public K-12 schools across the 50 states of the United States and the Federal district , spanning the years 2006 to 2021 while accounting for the effects of inflation. The study's results demonstrate an overall rise in per-student expenditure, yet it also highlights the presence of persistent and probably expanding disparities among different states. The differences identified in this research are attributed to the structural aspects of school financing in the United States. The text finishes by presenting policy ideas that address disparities and promote educational fairness, focusing on marginalized populations. These recommendations emphasize the strategic involvement of the government, market, and educational institutions in providing public services.
