Exams and tests at school have always had the purpose of helping educators understand how much of a subject students are absorbing, but testing has grown extreme in modern schools. Students are given quizzes and tests by their teachers on a regular basis to see if they understand the subject, but there are now regional and national tests students must take to measure their performance. Many countries have also added an extra layer of testing to determine if students have learned enough to progress to the next grade.
The amount of testing has begun to interfere in the modern classroom, and educators have been concerned it is taking away from their ability to properly teach students. Rather than imparting knowledge and giving students the ability to connect it, many teachers have begun to simply teach the information students will find on their tests. Narrowing their education in this way does not prepare students for their future roles in society, so it gives them only the ability to answer the test questions accurately.
