The source reliability is rated between A (history of complete reliability) to E (history of invalid information), with F for source without sufficient history to establish reliability level. The information content is rated between 1 (confirmed) to 5 (improbable), with 6 for information whose reliability can not be evaluated.

E.g. a scale that is 5 pounds off is reliable but not valid. A test cannot be valid unless it is reliable. Validity is also dependent on the measurement measuring what it was designed to measure, and not something else instead. [6] Validity (similar to reliability) is a relative concept; validity is not an all-or-nothing idea.
Reliability does not imply validity. That is, a reliable measure that is measuring something consistently is not necessarily measuring what you want to be measured. For example, while there are many reliable tests of specific abilities, not all of them would be valid for predicting, say, job performance.
Base articles on reliable, independent, published sources with a reputation for fact-checking and accuracy. Source material must be published, on Wikipedia meaning made available to the public in some form. [f] Unpublished material is not considered reliable. Use sources that directly support the material presented in an article and are ...
Consequently, some judgment and comparison of sources is needed in order to identify reliable sources. Reliable sources respect truth; a source that is commonly untruthful is not reliable. A source may be partly or more or less reliable. Concurrence of possibly reliable sources may help in identifying reliable sources, and editors should seek it.
For example, the Carvaka school of the Śramaṇa tradition holds that only one (perception) is a reliable source of knowledge, [8] Buddhism holds that two (perception, inference) are valid means, [9] [10] Jainism holds three (perception, inference and testimony) as valid, [10] and the Mimamsa and Advaita Vedanta schools of Hinduism hold that ...
