Why do critics argue that high-stakes standardized tests can narrow the curriculum?

Critics argue that high-stakes standardized tests can narrow the curriculum because they prioritize test preparation over a broad, well-rounded education. By focusing heavily on the specific content and formats measured by these assessments, schools may inadvertently neglect essential skills that are not easily captured by standardized testing, such as creative thinking and complex problem-solving.1

This over-reliance on testing can inhibit a school's ability to foster student success in diverse dimensions, such as identifying entrepreneurial talent or training students to address multifaceted, real-world issues that lack simple, predetermined answers. Furthermore, because high-stakes tests carry significant consequences—including potential school closures, teacher evaluations, and funding decisions—educators may feel pressured to "teach to the test," which often results in a restricted focus on the narrow range of subjects and skills that appear on the exams. This approach risks sidelining critical educational goals in favor of achieving higher scores on standardized metrics.12
