Validity [5] of an assessment is the degree to which it measures what it is supposed to measure. This is not the same as reliability, which is the extent to which a measurement gives results that are very consistent. Within validity, the measurement does not always have to be similar, as it does in reliability.
Test validity, validity in educational and psychological testing; Face validity, the property of a test intended to measure something; Construct validity, refers to whether a scale measures or correlates with the theorized psychological construct it measures; Content validity, the extent to which a measure represents all facets of a given construct
The exercise is also an important tool for demonstrating content validity when compared with the source. During the interview, the respondents complete the questionnaire, and then answer a series of open-ended questions on its content and explain what they think each item means in their own words.

An additional step is a language-dependent algorithm for handling morphology. Even for a lightly inflected language like English, the spell checker will need to consider different forms of the same word, such as plurals, verbal forms, contractions, and possessives. For many other languages, such as those featuring agglutination and more complex ...
All languages have some means of specifying the source of information. European languages (such as Germanic and Romance languages) often indicate evidential-type information through modal verbs (Spanish: deber de, Dutch: zouden, Danish: skulle, German: sollen) or other lexical words (adverbials, English: reportedly) or phrases (English: it seems to me).
There are generally four types of spelling tests. In an oral spelling test, the teacher pronounces each word out loud and the students write each word down. In a spelling bee-type test (see spelling bee below), each student is asked individually one-at-a-time to spell a (different) specific word out loud. In a proofreading-style test, sentences ...
An argument is valid if and only if it would be contradictory for the conclusion to be false if all of the premises are true. [3] Validity does not require the truth of the premises, instead it merely necessitates that conclusion follows from the premises without violating the correctness of the logical form.
