The bar charts provides information about changes in spending per pupil and percentage of students achieving passing grades in math and reading exams in the Riverdale Public School System from 2000 to 2015.
Overall, spendings per pupil decreased sharply, while the percentage of students passing remained stable during this period.
In 2000, spending per pupil was about $ 12000, however, this data has declined steadily over the years. By 2005, that figure had dropped to about $10,000, and by 2015, per pupil spending had dropped to its lowest level, just above $8,000.
Despite the reduction in costs, the percentage of students who successfully pass exams has changed very slightly. In 2000, it was about 87%, by 2005 it had slightly decreased to 85% and remained at this level until 2015.
This information suggests that reduced spending did not significantly impact students ‘ performance in tests over this time period.
