1. A method of assessing quality of language translation and interpretation, comprising the steps of: a) receiving on a computing device source material in a first language and a translation of the source material, where the language of the translation is selected from the group of languages consisting of a language that is different from the first language, a language that is the same as the first language but in a different dialect, and the same language as the first language, where a translation into the same language includes translation slang in a first language to proper speech in the first language; b) identifying on the computing device the source material's content and format; c) assigning on the computing device a first rating to the source material's level of difficulty in translating the source material based on the result of step (b); d) determining on the computing device the translation's type; e) assigning on the computing device a second rating to the translation's accuracy as compared to the source material for its type as determined in step (d); f) assigning on the computing device a third rating to the degree to which the translation interprets the source material's intended message; g) assigning on the computing device a fourth rating to the format of the translation; and h) evaluating on the computing device the results of step (c), step (e), step (f), and step (g) to determine an assessment of the translation's language translation and interpretation.
