As we spent more money on education in California, did our kids become better educated? 2003 Spend: $14,400 per pupil 2024 Spend: $24,000 per pupil Unfortunately, the answer is “NO”. Inflation adjusted per-pupil education spending in California increased 66.67% over the past 20 years. The correlation (r), though, across all grades, between spending and actual results is 0.122 which is described as a “very weak positive” relationship. In other words, spending the extra money didn’t result in any increase in educational outcomes and in some cases was correlated with worse outcomes (Grade 8 Math).
