The school commissioned a third-party platform to implement the examination test results are valid. This examination technology has been used internationally for many years and is known as cognitive diagnostic evaluation technology. The innovation lies in the combination of education cloud technology and big data mining technology to build an adaptive learning platform that can understand and determine the level position of the tested student among all students based on the student's previous examination records, comparing the examination records of all students, and provide students with academic diagnosis, analysis of academic potential, and personalized learning programs. Education Cloud is characterized by the fact that the more the number of students adopting the test and the more the number of tests, the more accurate the analysis it provides. Once a systematic talent database and education research database is formed, it will be able to provide accurate data for the comprehensive evaluation of the quality of primary and secondary education and the reform of the new college entrance examination, as well as for the national education quality standards and talent selection standards.
