Rigorous course participation rose after 2021 law, University of Illinois report finds

A new University of Illinois report reveals that participation in rigorous high‑school courses—dual credit and Advanced Placement (AP)—has climbed sharply since the passage of a 2021 state law aimed at expanding college‑ready curricula. The surge is especially pronounced among Black students and those with disabilities, signaling that policy interventions can help close longstanding equity gaps in advanced academic opportunities.

What Happened

In the 2022‑23 academic year, Illinois schools saw a 12 percent increase in dual‑credit enrollment and a 9 percent rise in AP exam registrations compared with the pre‑law baseline of 2020‑21. The report attributes the uptick to the 2021 Illinois Higher Education Access and Affordability Act, which mandated that all public high schools offer at least two dual‑credit courses and one AP class, and required districts to develop individualized plans for students with disabilities to access these programs.

Data collected from 212 public high schools across the state show that Black student enrollment in AP courses grew from 14.2 percent to 18.7 percent of total AP participants, while enrollment among students with disabilities rose from 9.5 percent to 13.4 percent. These gains reflect both increased availability of rigorous courses and targeted outreach efforts mandated by the law.

Key Details

The University of Illinois research team analyzed enrollment records, state exam scores, and surveys of school administrators. They found that schools that implemented comprehensive counseling programs—pairing students with mentors and providing tuition assistance for dual‑credit fees—experienced the largest participation jumps. For instance, Chicago Public Schools reported a 15 percent increase in dual‑credit enrollment after launching a district‑wide information campaign in early 2022.

Equity-focused provisions of the law also required districts to allocate at least 5 percent of their annual education budget to support students with disabilities in rigorous coursework. This funding was used to purchase adaptive technology, train teachers on inclusive instructional strategies, and subsidize exam fees, directly contributing to the observed rise in participation among this group.

Background

Prior to the 2021 legislation, Illinois lagged behind neighboring states in offering high‑school students access to college‑level coursework. Only 38 percent of public high schools provided any dual‑credit options, and AP participation rates among Black students and students with disabilities were consistently below the state average. Critics argued that the lack of rigorous coursework perpetuated achievement gaps and limited post‑secondary success for historically underserved populations.

The law emerged from a coalition of educators, civil‑rights advocates, and legislators who pushed for a statewide commitment to academic equity. It built on earlier federal initiatives, such as the Every Student Succeeds Act, by embedding specific enrollment targets and funding mechanisms at the state level. The legislation also introduced a data‑reporting requirement, compelling districts to publicly disclose participation rates for different demographic groups each year.

Why It Matters

Participation in dual‑credit and AP courses is strongly linked to higher college enrollment, increased likelihood of earning a degree, and better labor‑market outcomes. By expanding access for Black students and those with disabilities, Illinois is taking concrete steps toward narrowing the achievement and earnings gaps that have persisted for decades. Early evidence suggests that students who completed dual‑credit courses under the new policy were 22 percent more likely to enroll in a four‑year college than their peers who did not.

Moreover, the report underscores the importance of intentional policy design. The law’s requirement for individualized plans and dedicated funding demonstrates that simply offering courses is insufficient; systematic supports are essential to ensure that all students can succeed in demanding academic environments. This insight offers a model for other states seeking to replicate Illinois’s progress.

What Happens Next

State education officials plan to refine the law’s implementation based on the report’s findings. Upcoming legislative sessions will consider amendments to increase the minimum number of rigorous courses required per high school from two to three, and to boost the disability‑support budget to 7 percent of district expenditures. Additionally, the University of Illinois will conduct a longitudinal study to track the long‑term outcomes of students who participated in dual‑credit and AP programs after the law’s enactment.

School districts are also preparing to expand professional development for teachers, focusing on culturally responsive pedagogy and differentiated instruction for students with disabilities. By strengthening instructional capacity, districts aim to sustain the participation gains and translate them into higher completion rates for AP exams and successful transfer of dual‑credit credits to post‑secondary institutions.

In sum, the University of Illinois report highlights a promising shift toward greater academic rigor and equity in Illinois high schools. The 2021 law’s impact—evident in rising enrollment numbers and narrowing demographic gaps—demonstrates that targeted legislation, coupled with adequate resources and accountability, can reshape educational pathways for historically marginalized students. Continued commitment and data‑driven adjustments will be crucial to maintaining momentum and ensuring that the benefits of rigorous coursework extend far beyond enrollment statistics, ultimately fostering a more inclusive and prosperous future for all Illinois learners.
