What does unstandardized mean?
Unstandardized describes something that has not been made uniform, consistent, or compliant with an accepted set of criteria. The word is especially common in discussions of education, testing, research, manufacturing, and data collection. Unstandardized test scores, for example, may have been produced under different grading conditions or with instruments that cannot be compared directly. The term does not necessarily indicate that something is poor, unsafe, or invalid; it simply emphasizes the absence of an agreed standardization process. In many contexts, nonstandard is more familiar and equally precise, while unstandardized can be useful when the distinction between general irregularity and a specific lack of standardization matters. It is primarily a formal, technical adjective, and its use often prompts attention to consistency, comparability, and the need for shared criteria.

Where does unstandardized come from?
Unstandardized was formed in English by combining the prefix un- with standardized. Standardized comes from standard plus the suffix -ize, while standard entered Middle English through Old French and originally referred to a flag or banner used as an emblem. The development reflects the general English tendency to form negative adjectives with un- and to use -ize when describing the act or result of making something conform to a standard.
How unstandardized is actually used
This is a formal and often technical term, especially common in education, testing, research, manufacturing, and data collection. It normally appears before a noun and does not by itself imply that the thing described is defective or undesirable.
