A new analysis by Chad Aldeman for The Collaborative for Student Success reveals a stark “Graduation Gap” across US states: high school graduation rates remain high, yet math proficiency lags dramatically behind.
Examples include Florida (90% graduation vs. 44% proficient in Algebra/Geometry), Connecticut (89% vs. 31% college-ready on SAT math), Rhode Island (84% vs. 23%), Washington D.C. (86% vs. 15%), and Tennessee (92% vs. 29%). Gaps are wider in math than reading, larger with externally validated tests, and especially pronounced for low-income students, English learners, and those with disabilities.
