The College Board released its data on 2012 SAT scores on Monday, and beneath the headlines (which tallied how much SAT scores have slipped as more and more students take the test) was a revealing picture of the influence of students’ household income on their performance.
The influence couldn’t be more decisive. The board measured household income in increments of $20,000 – starting with students from households making $0 to $20,000 annually, then $20,000 to $40,000, all the way up to $160,000 – then an increment of $40,000 ($160,000 to $200,000) and then a final category of more than $200,000. And SAT scores rose considerably at every step in the income scale. The poorest students, from households making less than $20,000 had a mean combined score of 1322 out of 2400; the next highest, 1397; then 1458, then 1497 – all the way to a score of 1722 for students from households making more than $200,000. That’s a 400-point difference between our richest and poorest students.
