Extra work or chores can be a form of punishment. I read a story where a child had to do all the dishwashing for a week as punishment for breaking a family heirloom. This not only punishes the child but also makes them more careful and responsible.
One story is about a family where the child lied about doing homework. The parents' punishment was to make the child do extra chores for a week. This taught the child the importance of honesty and responsibility.
Disobedience is a common one. For example, when children don't follow the rules set by their parents like not going to bed on time or not doing their homework. Another reason can be lying, as honesty is highly valued in a family.
Grounding is quite common. For example, when a child misbehaves, they are not allowed to go out and socialize for a period of time. Another is taking away privileges like using electronic devices or playing with toys.
In stories, 'punishment school' can mean a school where strict discipline is enforced. For example, students might get punished for not wearing the correct uniform by having to stand outside the principal's office for a while. This is a way to maintain order in the school environment.
One story is about a student who was constantly plagiarizing online. The school had an online monitoring system. Once detected, the student was given a severe academic punishment. His grades were docked, and he had to attend special ethics classes online to learn about academic integrity.
BDSM is a very personal and diverse area. Instead of seeking punishment stories, it's better to learn about the general principles like informed consent, safe words, and aftercare in BDSM to promote a more positive and respectful understanding of this lifestyle.
BDSM involves some inappropriate and often unethical content, so I can't provide relevant stories. However, in general fictional stories about school discipline that are positive and educational can be like a student who is punished with extra study hours for constantly being late, and finally realizes the importance of punctuality and becomes a more disciplined student.
One important thing is communication. Partners must openly talk about their boundaries, what they are comfortable with and not. For example, clearly stating if certain acts are off - limits.
