How to read this list
Each school is scored on its most recent year carrying both a math and a reading (English Language Arts) all-students proficiency figure on Alabama's native assessment. The final column is the difference: math proficiency minus reading proficiency, in percentage points. A negative number means a school's students are more often proficient in reading than in math; a positive number means the reverse. Because both figures come from the same students taking the same test under the same cut-score policy, the gap is an apples-to-apples comparison in a way that raw cross-state proficiency rates are not.
A wide gap is not automatically a problem. Arts, language-immersion, and humanities-focused programs often post strong reading and weaker math; STEM and career-technical programs often do the reverse. But a persistent, schoolwide divergence is worth a parent's attention, because it can also flag a staffing gap, a curriculum weakness, or a math-anxiety culture that a single year of scores would hide.
What is excluded
Brick-and-mortar schools only: virtual academies and cyber charters are removed because their results are noisy and rarely reflect a school families choose geographically. Specialized-population schools (state schools for the deaf or blind, therapeutic and juvenile-justice placements, and NCES special-education or alternative-education campuses) are also excluded, because state proficiency rates are not a comparable metric for them. Schools must have at least 150 students and at least 5% proficient in each subject, a floor that drops suppression and coding artifacts.
