Declining Scores and Widening Gaps
The US decline was part of a broader international trend, with an OECD average across 23 countries also falling 16 points. However, the United States stood out for the size of its performance gap.
- 25.7 percent of US students were ranked as low performers in reading.
- 13.3 percent were flagged as top performers.
- No country among the 90 participants showed significantly wider inequality in reading scores than the US.
"Looking across all 90 participating countries, there was not a single country with significantly wider inequality in reading scores than the US," said Michael Kieffer, a professor of literacy education at New York University. "What is clear is that we are under-serving many students."
