For families focused on college preparation, two metrics matter above all others: high school graduation rate (does the system get students to the finish line?) and educational attainment rate (does the community culture support advanced education?). Counties that excel on both dimensions produce students who are not just college-eligible, but college-ready.
We built a composite "college-bound score" by averaging each county's graduation rate and educational attainment rate. The result is a ranking of the 25 counties most likely to prepare students for bachelor's degree programs and beyond. The average score across these top counties is NaN%.
The 25 Best Counties for College-Bound Students
Ranked by college-bound score (average of graduation rate and educational attainment rate).
| Rank | County | State | College-Bound Score | Graduation Rate | Attainment Rate | School Score |
|---|
Why Both Metrics Matter
A county with a 98% graduation rate but only 20% bachelor's attainment produces students who finish high school but rarely pursue four-year degrees. Conversely, a county with 85% graduation and 55% attainment may lose more students before graduation but send a higher share of graduates to college.
The best counties for college-bound students score well on both metrics. They have school systems that keep students engaged through high school and community cultures that expect and support college attendance. These counties are disproportionately found in affluent suburbs, university towns, and state capitals where education is central to the local identity.
Methodology
The college-bound score is the simple average of each county's four-year adjusted cohort graduation rate and its educational attainment rate (percentage of adults 25+ with a bachelor's degree or higher). Both metrics come from federal government sources: graduation rate from NCES and attainment rate from the Census Bureau ACS 5-Year Estimates (2019-2023). Counties missing either metric were excluded.
Data sources: National Center for Education Statistics (NCES) Common Core of Data and U.S. Census Bureau American Community Survey (ACS) 5-Year Estimates (2019-2023). All figures are estimates and may differ from other published analyses due to methodology differences.
