What does posttest mean?
A posttest is an assessment given after a period of teaching, training, study, or treatment. Its purpose is to measure what participants have learned, retained, or changed as a result of the preceding activity. Posttests are especially common in schools, universities, professional-development programs, research studies, and structured training. Teachers may compare posttest performance with earlier assessments to document improvement, while researchers may use posttest scores to evaluate an intervention. The word is less usual in everyday conversation because examinations, quizzes, and tests can be described more generally when their timing is already clear. As an attributive noun, it appears in established combinations such as "posttest results" and "posttest score." When used as a verb, posttest means to administer or undertake a test after instruction or another defining event. The term is the counterpart of a pretest, although posttest is especially associated with measuring final outcomes rather than initial knowledge or aptitude.
A test administered after instruction, training, or treatment to evaluate learning, retention, or performance.
"The class improved substantially between the initial assessment and the posttest."
Common in educational and research settings; often written "post-test" or "post test" when standing alone in prose.
To administer a test to, or assess someone after a period of instruction, training, or treatment.
"The instructor posttested the participants after completing the final module."
Less common than the noun and chiefly used in educational, research, and training contexts.
Used when referring to multiple assessments administered after instruction or another activity.
"The school compared the posttests from three separate classes."
A posttest is the educational equivalent of checking the score after the race: it shows where a learner ended up, not where they started.

Etymology of posttest
Posttest is an English compound formed from the prefix post-, meaning "after," and the word test. The prefix post- comes from Latin and is widely used in English formations indicating a position or occurrence after something. Modern educational usage developed the compound to distinguish assessment conducted at the end of instruction from testing carried out before it.
