Oregon school performance ratings

The state created a five-tier rating system designed to give slightly more than half of schools one of the top two ratings.
Level 5 schools: These 114 schools performed in the top 10 percent statewide.
Level 4 schools: This is the broadest performance category, covering 557 schools that ranked from the 90th percentile down to the 44th%
Level 3 schools: These 356 schools performed below average to well below average.
Level 2 schools: These 113 schools performed in the bottom 15 percent statewide. The federal government considers these schools in serious need of improvement.
Level 1 schools: These 54 schools rank in the worst 5 percent, and the feds consider them in dire need of improvement. They have low test scores, low student growth, poor achievement by low-income students or, for high schools, atrocious graduation rates.
