Parents and students can actually visit the institution, talk to the teacher about the actual situation of the students, see what the teacher's answer is, and whether they can give practical solutions to their own problems.
Then qualified students can also listen to one day or several classes in the institution to see how the teachers in this institution are and whether the teachers' teaching level is qualified. Then choose the best.
If there are some warranty agreements or other agreements, it is recommended that parents and institutions sign contracts to avoid disputes later.
