Abstract

Early-warning systems in schools and universities increasingly attach distribution-free guarantees to their decisions, bounding within every demographic group how often at-risk students are missed and how often students on track are flagged. Equalized conformal decision layers achieve this by referring ambiguous students to counselors, but they treat counselor workload as a by-product: at a 10% error level they refer 32% to 56% of a cohort, and because empty prediction sets are referred as well, relaxing the error level can even increase the workload. We propose Resource-Aware Fair Conformal Prediction (RAFCP), which takes the review capacity as an input and returns the strongest equalized guarantee that this capacity can support. RAFCP resolves empty prediction sets automatically, which pre-serves the group-level miss and false-flag bounds and makes re-ferrals nested in the error level; it certifies the level with a boot-strap capacity planner that uses only cross-fitted training scores, so finite-sample validity is retained; and it reconciles the plan with the screened cohort so that exactly the budgeted number of students is referred. We further prove that equal error levels across groups are minimax-optimal under any monotone capacity constraint. On three public U.S. cohorts (Tennessee STAR, High School and Beyond, and the LSAC Bar Passage Study) with 30 stratified splits, RAFCP lowers the worst-group automated error at a 10% referral budget from 0.43, 0.38, and 0.58 under confidence-based deferral to 0.19, 0.28, and 0.22, keeps between-group gaps below 0.02, and outperforms each deferral baseline in at least 27 of 30 paired splits.
