There are many factors to having an accurate speaking test; however, Language Testing International is one of the best places to have that test done. Licensed by the ACTL, or the American Council for the Teaching of Foreign Language, LTI provides linguistic assessment that makes sure the subject can accurately speak the language, both in terms of the literal words as well as understanding the culture, specific idioms, and finally even the accent as well. A linguistic test covers a variety of topics, but provides the certification that the speaker is not only proficient, but entirely fluent.
On aspect of fluency is the difference between academic and conversational dialogue. While most people measure fluency in terms of being able to speak the language, there is a secondary level which consists of more academic, professional, or scientific language. In terms of being able to speak a language, conversational word choice and syntax is often sufficient; after all, in terms of getting through one’s day, most discussion, word choice, and complexity will be nothing larger than having to discuss day to day affairs, meals, and so forth.
Beyond simple conversational language, however, is academic language that is present in many scholarly, educational, or professional settings. Being able to pass a verbal test that focuses on elements of spoken rhetoric, high level word choice, and complicated sentence structure ensures that the subject is able to engage in the language on multiple levels and at a variety of complexities.
There are many reasons to consider taking a language test that focuses on speaking skills. Many companies that offer additional pay for a second language skill, such as customer service centers that offer second language options, require a speaking test to be able to prove that the employee can actually speak, fluently, the language desired.
One of the reasons that Language Testing International is considered to be the most reliable language test on the market is because of their reputation for both testing validity and reliability. In terms of assessment theory, validity centers around the idea that a test is valid, or accurate, on the topics that it claims to measure. In the case of a language test, the things which are measured vary, but include specific items on the subject of accent. Often, a language will have two words which are incredibly similar but differ in meaning based strictly on accent. In those cases, it is not enough to simply know the word, but also to understand how it is spoken correctly.
Finally, LTI is widely acclaimed for the reliability of their speaking test because of the academic rigor involved in its construction. In terms of language, there is none better.
