q2 i? Compared with schools where less than 10% of students are FRL-eligible, schools with more than 90% FRL have 15% more schools whose median growth is below the 50th percentile and 3% more whose growth is above the 82nd percentile. → Andy Hegedus 2018

q2 · i? · associational · r2

Observational comparison of growth distributions for schools with %FRL less than 10% versus greater than 90% (Figure 2.3). The article reports the lowest income schools show more schools growing at both lower and higher median growth percentiles, with "15% more schools whose median student growth is below the 50th percentile and 3% more whose growth is above the 82nd percentile."

"The lowest income schools have 15% more schools whose median student growth is below the 50th percentile and 3% more whose growth is above the 82nd percentile."

Discussion¶

Related Claims¶

• School poverty (%FRL) accounts for about 50% of a school's median student achievement — related
• School poverty is only weakly associated with median student growth in a school — related
• Sixty percent of the highest-poverty schools also have above-average student growth — related
• 77% of the lowest 5% achieving schools (spring reading) grow their typical student better than the 30th percentile — related
• High-poverty schools' high achievers had roughly even odds of above-average growth, and 75th-percentile growth would be needed to close the readiness gap — related
• Massachusetts students overall perform above the national average on screening assessments, with a median national percentile of 58 at EOY and 66 percent growing at average or above-average rates — related
