Academic probation counts as IA. On AACOMAS they ask, "Have you ever been disciplined for academic performance (e.g. academic probation, dismissal, suspension, disqualifification, etc.) by any college or school?" If yes, you have to explain.
I was also put on academic probation about 10 years ago. I failed a writing class my freshman year. I just gave a short explaination and said what I did to change it and how I made Dean's List the next semester. I was actually asked about it during my interview, but I was still accepted by the school anyways.
