Early Intervention

Trust your instincts. Your son seems to be fine with his communication. I am wary of such programs. Not that the people involved don't really care and think they are doing good, I just don't like the idea of some government program labelling a kid when it's unnecessary and I would never allow unknown people from some "program" into my home.

All kids develop their speech and communications skills at a different rate. If in the future you become concerned do some research, talk to other parents and I'm sure you will do whats best for your child, not what some program thinks is best.
