The No Child Left Behind Act of 2001 (NCLB) represented, in the United States at least, the triumph of measurable outcomes over meaningful learning. Under its regime, schools were judged by their students’ performance on standardised assessments. The consequences of poor scores were severe: funding cuts, staff dismissals, school closures. The entirely predictable result was what educators came to call “teaching to the test,” a practice in which classroom instruction was narrowed to the specific content and formats that would appear on state exams.
The effects were devastating and well-documented. Subjects not covered by standardised tests, including art, music, physical education, and social studies, were minimised or eliminated outright. Some principals eliminated recess to devote more time to test preparation. Science was replaced with additional maths drills. Social studies gave way to language arts worksheets. The phrase that captured this era most succinctly was “sit, get, spit, forget,” a cycle in which students received information passively, regurgitated it on an exam, and promptly forgot it, having never engaged with it at any depth.
The situation in the United Kingdom has followed a parallel trajectory. Successive reforms since the introduction of the National Curriculum in 1988, the expansion of league tables in the 1990s, and the intensification of Ofsted inspections have created an accountability culture that rewards measurable outcomes above all else. Teachers in England report spending enormous amounts of time on assessment preparation, data tracking, and administrative compliance, time that might otherwise be devoted to the kind of open-ended, inquiry-driven teaching that develops critical thinking. The Department for Education published expanded guidance on AI in education in June 2025, stressing that AI tools should support rather than replace subject knowledge and that students still need a strong foundation in reading, writing, and critical thinking to use these tools effectively. But guidance is one thing; structural reform is quite another.
