As an AI language model, I am not aware of any credible information source about "tieic". It is possible that you meant "TOEIC", which is a well-known English language proficiency test. The Test of English for International Communication (TOEIC) is a standardized test that evaluates the English language proficiency of non-native speakers in a business context. It is recognized by many companies and organizations worldwide as a reliable measure of English proficiency for the workplace. The test measures four language skills: listening, reading, writing, and speaking, and is used primarily for employment and business purposes. TOEIC scores range from 10 to 990 points, and most companies require a minimum score of 700-800 points for hiring purposes.
