I have a student in my classroom this year that I am having a lot of trouble dealing with and was hoping that someone here may have some advice. I had already been warned about this student prior to the school year based on her experience in first grade. The student has diagnosed ADHD and is on medication for it. The first four weeks of school ran smoothly without any major issues with the student. However, this week she ran out of medicine and turned into a completely different person. There were two major melt-downs this week. Both were pretty similar, but it was worse today. As we prepared to take a test today and the class moved quietly to their seats, the student refused to sit in her seat. A countdown began for her to move to her seat and the student still did not move, so my assistant picked up the phone and dialed her mom. The student stated she did not care if we called her mom. We were not able to reach Mom. At this point, the student stood up and then started hopping on all fours around the room making loud animal noises while the other students sat in silence, unsure of what to do. My assistant opened the door to walk her down to the office, and she bolted out the door. I continued on with the test. I was told that my assistant had to chase her down the hall until she was restrained by a teacher in the hallway and carried to the front office where she began biting, spitting and kicking the office staff. Many of my students expressed to me that they had witnessed similar incidents regularly last year. As I mentioned previously, the student takes meds for ADHD, which seem to be working. However, I want to prepare in advance if a similar incident happens again since I work in a low-income school where her mom may let her prescription run out again due to lack of money. I also do not have an assistant to help me in circumstances like this every day of the week. Occurrences like this are a huge distraction to the entire class, so I am looking for any ideas to deal with a child like this and if anyone has any previous experience working in any type of similar situation? I am not sure exactly what sorts of things set her off, but I know the past two times it has been when she did not want to take a test.
