This paper introduces a Selective Error-Correcting Adaptive Quadrature algorithm (SECAQ), a method designed to address this issue. SECAQ identifies intervals with large local error or sharp changes, estimates jump sizes using one-sided evaluations, and applies compact correction terms activated only near the discontinuity. These localized corrections restore smoothness within each subinterval and can enable the base quadrature rule to achieve its full theoretical accuracy. Numerical tests involving jumps, cusps, and oscillatory functions demonstrate that SECAQ restores fourth
