1, some IT training institutions have loose and chaotic management, low technical management level and far from institutionalized management. For example, the teaching progress and curriculum arrangement of many institutions will change at will, and whether the teaching promise is fulfilled depends entirely on the individual wishes of the lecturers.

2. Exaggerated false propaganda is widespread. For many students who want to enter the IT industry, the high salary in the IT industry is undoubtedly the primary factor to attract them. Therefore, many training institutions will attract students by exaggerating or even forging glamorous employment data. Therefore, we should not blindly believe the high salary advertised by training institutions, but should compare more objective data (such as the data of third-party recruitment platforms).

3. Unscreened enrollment seriously affects the quality of training. Many organizations will promote zero foundation and participate in IT training to achieve high salary, but zero foundation refers to zero foundation of IT skills, not programming with poor learning logic level and understanding ability. The unfiltered enrollment will only damage the reputation of IT training, as evidenced by the accusations against IT training on the Internet.
