Should your local high schools prioritize offering college credit courses to students?

Connecticut high school students achieved a record 91.2 percent four-year graduation rate for the 2025 cohort. This historic milestone marks the highest performance since the state began tracking this data in 2010-11.

Why it matters

The record graduation rate and increased college course completion suggest improved student engagement and expanded academic opportunities across the state. These gains are attributed to targeted state grants and partnerships with higher education institutions that bolster coursework access.

The 2025 cohort reached a 91.2 percent graduation rate, while students completed 53,000 college-level courses in 2025-26, a 70 percent increase from 2021-22. These achievements occur alongside improvements in addressing chronic absenteeism, defined as missing 18 days or more of school.

The players

UConn

The state's flagship public university system that provided dual-credit coursework to more than 20,000 students.

The details

Students accumulate college credits through a mix of methods, including meeting benchmarks on SAT, ACT, AP, or IB exams. Additionally, school districts have increased dual enrollment options and other engagement pathways to help students earn credit. These initiatives, supported by state funding, have substantially increased the volume of college-level work completed by high school juniors and seniors.

Timeline

  1. 2010-11: Data collection for four-year graduation rates began.

  2. 2021-22: Approximately 30,000 college-level courses were completed.

  3. August 2026: Statewide test score results were released.

The Home Front

The state's recent academic performance marks the third consecutive year of growth on the Connecticut Accountability Index. This trend reflects an broader effort to stabilize student outcomes following years of disruption in secondary education.

Parents of high school students should review their district’s course catalog to identify available dual-credit or AP enrollment windows for the upcoming semester. Tracking attendance is also essential, as addressing absences early remains a key factor in long-term academic success.

The takeaway

The record-setting graduation data underscores the growing importance of earning college credit before leaving high school. Families should check in with school guidance counselors to ensure their student is maximizing available dual-enrollment opportunities.
