When comparing test scores between private schools and public schools, it's often challenging due to fundamental differences in their student populations. Public schools are mandated to accept all students from a given area, regardless of academic ability or background. In contrast, private schools can choose who they admit, usually selecting those with higher potential for success based on various criteria like entrance exams or interviews. This selective nature means that comparing the performance outcomes of these two types of institutions is not straightforward and may not provide an accurate reflection of their effectiveness.
The quote highlights a significant issue in educational assessment: the disparity between public and private schools' admission policies can distort comparisons of academic achievement. Public schools face more challenging circumstances because they serve all students, including those with special needs or difficult home environments. This diversity can lead to lower average test scores compared to private institutions that tend to have smaller classes and a more homogeneous student body in terms of academic aptitude and financial support from parents. Such comparisons often fail to account for these systemic differences, which is why the speaker argues that it's not fair to judge their performance solely on standardized test results.
