Tests vary in style, rigor and requirements.

For example, in a closed book test, a test taker is often required to rely upon memory to respond to specific items whereas in an open book test, a test taker may use one or more supplementary tools such as a reference book or calculator when responding to an item.

A test may be administered formally or informally.

An example of an informal test would be a reading test administered by a parent to a child.

An example of a formal test would be a final examination administered by a teacher in a classroom or an I.Q.

test administered by a psychologist in a clinic.

Formal testing often results in a grade or a test score.

A test score may be interpreted with regards to a norm or criterion, or occasionally both.
