What is an achievement test?

An achievement test is a standardized test designed to measure a person's knowledge and skills in a specific area or subject. Unlike aptitude tests, which predict future performance, achievement tests assess what someone has already learned. They are used to evaluate the effectiveness of instruction, identify areas of strength and weakness, and inform educational decisions.

Key characteristics of achievement tests include:

* Standardized administration and scoring: This ensures fairness and comparability across individuals.

* Specific content focus: They measure knowledge and skills in a defined area, such as math, reading, science, or a specific course.

* Objective scoring: The scoring is typically based on predetermined criteria, reducing bias.

* Norm-referenced or criterion-referenced: Norm-referenced tests compare a person's score to the scores of others, while criterion-referenced tests assess performance against a predetermined standard or criterion.

Examples of achievement tests include:

* Standardized tests in schools: State-mandated tests, end-of-course exams, and subject-specific achievement tests.

* Professional licensing exams: Tests required to become a doctor, lawyer, or other licensed professional.

* College entrance exams: While they often include aptitude components, they also assess accumulated knowledge.

In essence, an achievement test provides a snapshot of a person's current mastery of a particular subject matter.
