Alvin ISD received a score of 89, or a B rating, in the Texas Education Agency's 2018-19 accountability ratings. Last year, AISD was not rated due to Hurricane Harvey. The score is based on a combination of three categories: student achievement, school progress and closing the gaps. Student achievement measures how much students know and are able to do by the end of the year. In this category, AISD received a B this year. The higher score between student achievement and school progress is used to determine the overall rating. AISD received an A in school progress, or the measure of how students perform over time and how that growth compares to similar schools. The closing the gaps category, or a measure of how well different populations of students are performing, makes up 30% of the overall score. AISD received a B in this category this year.
