Educational measurement terminology provides the foundation for describing how knowledge, skills, attitudes, and performance are assessed. Clear definitions help educators interpret scores accurately and make informed decisions about instruction, evaluation, and student achievement.
Terms such as validity, reliability, assessment, testing, scales, and standardization represent essential concepts within educational measurement. Understanding their meanings promotes precise communication and supports fair, meaningful, and evidence-based educational practices.
Educational measurement terminology refers to the specialized language used to describe how learning, knowledge, skills, and abilities are assessed. Understanding these terms helps educators interpret assessment results accurately and communicate findings clearly.
Common terms include assessment, test, measurement, and evaluation. Assessment is the broader process of collecting information about learning, while measurement assigns numerical values to performance. A test is one instrument used to obtain that information, and evaluation involves judging its value or quality.
Validity describes whether an assessment measures what it is intended to measure. Reliability refers to the consistency of results across different occasions, forms, or scorers. A valid assessment should also provide dependable evidence for the intended purpose.
Other important terms in educational measurement terminology include norm-referenced and criterion-referenced assessments. Norm-referenced results compare a learner’s performance with that of a defined group, whereas criterion-referenced results indicate whether the learner has met specified standards or outcomes.
