Standardized assessments are designed to be administered under specific, standard conditions, resulting in a uniformity in testing environments and administration procedures. Standardization allows for the testing conditions to be equal for all test takers, enabling statistical comparison against the norm or criteria.
A term that describes a way of giving, scoring, or reading tests or surveys; if a test is standardized, it is like other tests and the information taken from all of them can be compared.
TEST: a measure that has been piloted (usually on a large sample, representing different types of respondents) and for which interpretive data, such as norms, reliability, and validity coefficients have been provided; has been administered to a large group of examinees from a target population, often more than 1000 persons, and has been analyzed and normed for use with other samples from that population.
Data is standardized when all the values in the distribution have been transformed to z-scores (see z-scores).
transformed to accord with a unit normal distribution.
A set of consistent procedures for constructing, administering, and scoring an assessment. The goal of standardization is to ensure that all students are assessed under uniform conditions so that interpretation of their performance is comparable and not just influenced by differing conditions (Brown, 1983).
