Noor Lyra TutoringWhat researchers studied
Large observational longitudinal study using California administrative data, prior eighth-grade math achievement, within-district comparisons, covariate adjustment, and matched comparisons to examine who fails dual enrollment and how failure relates to later college enrollment. Approximately 1.74 million California public high-school students from cohorts entering ninth grade from 2015-16 through 2018-19; dual-enrollment participants were compared by prior achievement and socioeconomic status, with a matched nonparticipant analysis among students who never took AP courses
What they found
- Overall, 17.1% of dual-enrollment participants received a failing grade in at least one dual-enrollment course.
- Socioeconomically disadvantaged students were more likely to fail dual enrollment at every level of prior eighth-grade math achievement, and the gap widened among higher-achieving students; in the highest achievement band reported in the policy summary, failure rates were 10.5% versus 5.8%.
- Failing a dual-enrollment course was associated with a 12.2-percentage-point lower likelihood of college enrollment than passing among otherwise similar dual-enrollment participants.
- Among students who never took AP courses, those who attempted dual enrollment and failed were still 6.4 percentage points more likely to enroll in college than matched students who never attempted dual enrollment.
What the study does not prove
- This is a 2026 EdWorkingPaper and should not be described as a peer-reviewed journal article unless a later publication is independently verified.
- Students were not randomly assigned to dual enrollment, failure, or nonparticipation, so the matched and adjusted comparisons should not be interpreted as definitive causal effects.
- The study cannot determine why disadvantaged students with similar prior achievement failed at higher rates; explanations such as financial pressure, navigation barriers, belonging, scheduling, or support gaps are plausible but not directly tested here.
- The findings come from California's dual-enrollment context and should not be generalized automatically to every state, college partner, course type, or individual student's readiness.
Evidence strength: Large-scale observational and matched longitudinal evidence; approximately 1.74 million students; EdWorkingPaper with Annenberg Policy & Practice synthesis.
Why this matters for families
Trying advanced coursework and struggling can carry real consequences, but this study suggests that the answer is not simply to gatekeep opportunity. Families should pair access with preparation and support, especially for students whose prior achievement indicates they are capable but whose environment may make the transition harder.
Noor interpretation
How Noor translates the evidence into practice
The strongest Noor-relevant lesson is that access and readiness should not be collapsed into one question. A student can be academically capable of advanced work and still need navigation, study systems, confidence, scheduling support, or targeted academic help to convert opportunity into success. Failure also should not automatically be read as proof that the student never belonged in the advanced pathway.
For Noor Lyra students considering dual enrollment, AP, or other advanced coursework, preparation should include more than checking a prerequisite grade. Review content readiness, executive-function demands, time management, instructor expectations, and the student's support plan before the course begins. If a student struggles, intervene early rather than using one failure as a reason to close the advanced pathway entirely.

Research notes
No single study determines a student's plan. Noor uses research as one input alongside the learner's goals, observed performance, academic context, and response to instruction.
