About tests

Some countries such as the United Kingdom and France require all their secondary school students to take a standardized test on individual subjects such as the General Certificate of Secondary Education (GCSE) (in England) and Baccalauréat respectively as a requirement for graduation. These tests are used primarily to assess a student's proficiency in specific subjects such as mathematics, science, or literature. In contrast, high school students in other countries such as the United States may not be required to take a standardized test to graduate. Moreover, students in these countries usually take standardized tests only to apply for a position in a university program and are typically given the option of taking different standardized tests such as the ACT or SAT, which are used primarily to measure a student's reasoning skill. High school students in the United States may also take Advanced Placement tests on specific subjects to fulfill university-level credit. Depending on the policies of the test maker or country, administration of standardized tests may be done in a large hall, classroom, or testing center. A proctor or invigilator may also be present during the testing period to provide instructions, to answer questions, or to prevent cheating.

Grades or test scores from standardized test may also be used by universities to determine if a student applicant should be admitted into one of its academic or professional programs. For example, universities in the United Kingdom admit applicants into their undergraduate programs based primarily or solely on an applicant's grades on pre-university qualifications such as the GCE A-levels or Cambridge Pre-U. In contrast, universities in the United States use an applicant's test score on the SAT or ACT as just one of their many admission criteria to determine if an applicant should be admitted into one of its undergraduate programs. The other criteria in this case may include the applicant's grades from high school, extracurricular activities, personal statement, and letters of recommendations. Once admitted, undergraduate students in the United Kingdom or United States may be required by their respective programs to take a comprehensive examination as a requirement for passing their courses or for graduating from their respective programs.

Standardized tests are sometimes used by certain countries to manage the quality of their educational institutions. For example, the No Child Left Behind Act in the United States requires individual states to develop assessments for students in certain grades. In practice, these assessments typically appear in the form of standardized tests. Test scores of students in specific grades of an educational institution are then used to determine the status of that educational institution, i.e., whether it should be allowed to continue to operate in the same way or to receive funding.

Finally, standardized tests are sometimes used to compare proficiencies of students from different institutions or countries. For example, the Organisation for Economic Co-operation and Development (OECD) uses Programme for International Student Assessment (PISA) to evaluate certain skills and knowledge of students from different participating countries.
