use the internet
Use major search engines to query, such as Tianyan Search and Enterprise Search, to query all kinds of information about related companies, establishment time, campus distribution, majors opened, cooperative colleges, etc. These are all things that need attention, and many advertisements have no reference value at first glance, so don't pay attention. Then they will check their authorization information in official website to see if the organization has authorized cooperation.
Look at the teacher's professionalism
Whether there is a professional team of teachers is one of the important references for students to choose institutions. Formal and reliable adult education and training institutions will have professional teachers, accompanied by class teachers, to help solve various problems of students, saving a lot of unnecessary time. But if, like Taobao customer service, all your questions are floating and there is no answer, it will definitely not work. If the teacher is more professional and really thinks about the candidates, that's not bad.
Reference netizen evaluation
The network can be regarded as a vent channel, and both praise and criticism are said online. I think this is particularly practical. There is industry propaganda or trampling on each other, but it doesn't matter. If it is really good or bad, the general trend of comments is one of them. You can judge by observation. In the comments, you can also get some information about the organization, such as work efficiency, attitude, and the authenticity of the test certificate.
On site consultation
If it's close to you, it's better to go to the site for consultation and find out for yourself, which is more reassuring.
