An oral warning can be permissible in training as a way to provide immediate feedback and correction to a trainee. However, it is important to follow up with written documentation to ensure clarity and accountability.

Separating a school class based on performance can be a controversial issue. On one hand, it can allow for more targeted instruction and support for students who may need extra help or challenge.

Ultimately, the decision to separate a class based on performance should be made carefully, taking into consideration the potential impact on students' self-esteem, motivation, and overall educational experience. It is important to ensure that all students have access to high-quality instruction and support, regardless of their performance level. **
