Public English Test System (PETS) is a national English proficiency test system designed and managed by the Examination Center of the Ministry of Education. As an educational exchange and cooperation project between the Chinese and British governments, it received technical support from British experts in the design process. The level is divided into pets-1 to 5. The textbook used is \ x0d \ x0d \ grade division \ x0d \ pets- 1: the first grade is the initial grade, and its test requirements are slightly higher than the English level of junior high school graduates (pets- 1b is the subsidiary grade of the national English proficiency test). \ x0d \ pets-2: Level 2 is the middle and lower level, which is equivalent to the English level of outstanding graduates of ordinary high schools (the written test scores qualified at this level can replace the English test scores of self-study exam (I) and diploma exam). \ x0d \ pets-3: Level 3 is an intermediate level, which is equivalent to the level of China students who have studied public English in colleges and universities for two years after graduating from high school or have taught themselves English courses of the same level. (The qualified written test scores at this level can replace the English (II) test scores at the undergraduate stage of the self-study exam. ) \ x0d \ pets-4: CET-4 is the upper-middle level, which is equivalent to the level of China students who have studied public English for at least 3-4 years at university or who have taught themselves English courses of the same level after graduating from high school. \ x0d \ pets-5: Band 5 is the highest level, which is equivalent to the level at the end of the second year of college English major in China. It is an English proficiency test specially designed for those who apply for public study abroad. \ x0d \ x0d \ CET refers to the College English Test, that is, the National College English Test, which is a national teaching test managed by the Ministry of Education. Its purpose is to objectively and accurately measure the actual English ability of college students and provide services for college English teaching. College English test is also a large-scale standardized test, and its design must meet the quality requirements of large-scale standardized test in educational measurement theory, and it is a "norm reference test related to standards". CET-4 and CET-6 have attracted the attention of Chinese universities and relevant education leading departments, and stimulated the enthusiasm of teachers and students. A large number of statistical data and experimental materials prove that CET-4 and CET-6 not only have high reliability, but also have high validity, which meets the quality requirements of large-scale standardized examinations and can reflect the English level of college students in China according to the requirements of the syllabus, thus effectively promoting the implementation of college English syllabus and improving the teaching level of college English in China. \ x0d \ \ x0d \ Difference from CET \x0d\( 1) In terms of questions, PETS has an oral test, but CET does not. PETS sets questions according to the actual needs of communicative competence inspection at all levels, mainly including: objective questions-multiple choices, choice compatibility; Semi-objective test questions-correcting mistakes, filling in the blanks, and simply summarizing; Subjective questions-thesis writing, translation, oral examination. \x0d\(2) In practice, because PETS pays more attention to the cultivation of communicative competence and interactive learning, it can improve learners' English level in an all-round way, thus giving full play to the role of English in practical application. \x0d\(3) In terms of social recognition, PETS was promulgated by the Ministry of Education, and its authority is beyond doubt. Moreover, the Ministry of Education is vigorously promoting this kind of examination and making it the only standard for all employers in China to measure the English level of English majors. \x0d\(4)PETS Band 3 is roughly equivalent to CET Band 4, PETS Band 4 is roughly equivalent to CET Band 6, and PETS Band 5 standard is equivalent to the level of college English majors in China at the end of the second year. \x0d\(5) Social candidates cannot apply for CET-4 and CET-6.
