First, look at the courses and see whether the courses of the training institutions are comprehensive and the course knowledge is detailed. A comprehensive and scientific course has its own learning system, which can make your study more effective.
Second, depending on the number of students, some schools have 50-70 students in a class, which is basically not considered. If there are too many students, basic teaching cannot be guaranteed. There are 25-30 students in a class, and teachers can cover everything.
Third, look at teachers instead of academic qualifications, and look at work experience. IT technology comes from practical work, and teachers with project experience are more likely to drive students' learning and development.
Fourth, look at the brand, run a school for a long time and have a certain educational history. Not every training school can have a history of more than 10 years, so continuing to run schools is bound to have advantages.
