Is the student struggling in any areas, such as: reading, writing, speaking, listening, math, science, eye contact, social skills, motor skills, self awareness, self control, etc.
The child struggles in many areas or is displaying exceptionally bad performance in just one or a few.
Speak to the student and ask them about their struggles. Approach the topic with the parents to gain some potential background information. Employ various strategies in the class to help the student succeed. If there is little to no responsiveness to my strategies, it could be a bigger issue.
