So much is measured by numbers, this measurement is an incomplete picture of what the student really knows. To truly measure a student, standardized tests are a failure because they don't measure all the capabilities of a student. These tests just reflect one day of the child's life, not an entire year's worth of learning. Also there are many factors that affect student learning and performance during the school year, and on that day of the test. I have been teaching for the past 7 years in the public school, high school, and college, and I know that the education system is relying on a broken system where the higher socioeconomic status can afford tutors, and supplies. Where as, the communities that are of lower socioeconomic status, suffer low scores because of the lack of supplies, tutors, and broken homes. There should be more than one way to measure students, not just a standardized test that doesn't fit everyone's concept of education. There are so many factors that affect the scores, that many teachers know that it is very unreliable, yet the system pushes it, and the children are punished for being in an area of lower socioeconomic status.
What I think is more interesting is modifying the way in which tests are programmed (specially in the francophone world).In such academic systems,students worry about marks and forget the concept and the utility of learning.For example,In my country,we study a lot of sciences and disciplines we don't need in our professional career and we have to success in their hard exams if we want to pass to the next class,so,a part of job is spending hours learning by heart exercises and formulas that we don't understand and we forget them after the exams in order to provide some memory area for the next subjects.
Some system of accountability is essential to maintain school quality. Standardized tests are designed to enable us to compare the performance of students in a relatively efficient way. Standardized tests are a fair and objective measure of student achievement, that they ensure teachers and schools are accountable to taxpayers. 93% of studies have found student testing, including the use of large-scale and high-stakes standardized tests, to have a "positive effect" on student achievement, according to a peer-reviewed, 100-year analysis of testing research completed in 2011 by testing scholar Richard P. Phelps. China, a country with a long tradition of standardized testing, topped all countries in the international rankings for reading, math, and science in 2009 when it debuted on the Programme for International Student Assessment (PISA) charts
