Hi there. I can't say whether this is the term or not without context, but I did see it used with IEP to mean Foundations of Technology. Hopefully that works in your context.
Initially I thought it may have something to do with Occupational Therapy, as 'experts' often use the term OT as a short form.
Just by the by, you may also consider using custom photo picture symbols. We tried that with our son and it made a HUGE difference, especially with behaviour. It worked so well that I actually began my 'web-life' by setting up to offer them to other parents and teachers as well. You can find more info here if you're interested:
