Private unaided schools have higher test scores and add more educational value than other school types. However, they tend to serve more advantaged students from wealthier families with higher levels of education. Not all private schools are equally effective - those charging higher fees, located in urban areas, and larger in size achieve better learning outcomes. While private unaided schools may provide better education, this disproportionately benefits higher ability and more advantaged children, raising concerns about inequality of opportunity. Prior academic achievement remains the strongest determinant of learning, indicating performance gaps emerge early in students' schooling.
