My biggest challenge faced at my current job would have to pertain to working with a student that was extremely aggressive, both towards himself as well as his peers and other staff. To resolve this problem, we looked at various methods on how to work with the student via like ABA programming. I have been sent to different trainings for my job, so I resorted back to some of the notes that we took during those trainings, and we had to essentially go through trial and error for this student, but essentially we came up with a plan and the plan worked and now we're seeing a decrease in challenging behaviors from the student and an increase of positive behaviors.
