Do most US high schools emphasize learning based on tests?

I read somewhere that most US high schools emphasize learning based on tests, as opposed to practical knowledge. Could anyone throw some light on this? Is there any truth to this claim?

Indeed, it's a commonly held view that many U.S. high schools focus significantly on test-based learning. This approach might not be ubiquitous across all schools, but it's certainly prevalent, particularly in public schools. There's a lot of emphasis on standardized tests, such as end-of-course exams and statewide assessments, which tend to evaluate more on recall and application of facts and concepts rather than practical knowledge and skills.

For example, a significant metric for high school ratings and funding is based on student scores in statewide standardized tests. This creates an environment where teachers might feel compelled to "teach to the test", focusing more on the content that they know will be tested rather than providing a more holistic or practical learning experience. This is not just about the subject matter but also extends to test-taking strategies and understanding the structure of such exams.

However, it's worth noting that there's a growing movement towards competency-based education, which focuses on students demonstrating mastery of specific skills or knowledge areas, and project-based learning, which encourages students to learn by actively engaging in real-world and personally meaningful projects.

Remember though, the quality and nature of education can vary widely between different high schools, districts, and states. Some high schools may have a more hands-on approach, incorporating internships, co-op education, and practical applications of theoretical knowledge. Others might focus intensely on preparing students for standardized tests. It's a mixed bag, largely dependent on the specific policy and culture of each educational institution.
