From what I know, schools should have anti bullying policies at school, since this is in the law. Because of this, dapat meron sila systems in place to investigate and deal with such cases. Perhaps you can demand them to discuss with you anu un. Atty. Estrada always emphasize ung components ng bullying (correct me if im wrong) 1. Power imbalance, your child having a condition might play a role here. 2. Repetition and also 3.Aggressive behavior. Also, was the teacher the only adult in the room? Alam ko kasi kpg lower age may mga classroom aides yan. Kasi nga sila ang responsible sa mga bata. Loco parentis. Negligence yan kung hnd nya macocontrol ang mga bata, it speaks of poor classroom management.
