The two bar charts illustrate the financial investment per student and the corresponding academic success rates at Riverdale Public School between 1990 and 2010. Overall, both metrics followed a steady downward trajectory over the two decades, suggesting a correlation between reduced funding and lower student performance.
In 1990, spending per pupil stood at $12,000, which was the highest figure recorded. This amount declined consistently every five years, falling to $10,000 in 1995, $9,000 in 2000, and $8,000 in 2005. By the end of the period in 2010, the expenditure had dropped further to $7,000, representing a total decrease of approximately 42% from the initial 1990 level.
Regarding academic performance, the percentage of students obtaining passing grades also saw a gradual decline. Starting at 87% in 1990, the figure dipped to 86% in 1995 and 85% in 2000. This downward trend continued, with the pass rate reaching 84% in 2005 and finally 82% by 2010. While the decline in academic performance was less pronounced than the sharp reduction in school funding, the data indicates a persistent negative trend in both categories throughout the observed timeframe.
