The individual skills and challenges that each person on the autism spectrum presents is truly fascinating. I always say that the "I" in IEP must have been specifically designed for "individuals" with Autism. Each and every IEP I have ever worked on have been a truly individual design. The goals and objective, the assessments are all unique, and the ways we all come up with on how to achieve these milestones are just as unique.
This can make the IEP process confusing for parents who assume that everyone gets the same as everyone else. But, as the experienced IEP team members know, that's not the case. And that fact has both positives and negatives to it - the positive is that no 2 kids are alike so it would be disastrous to start treating them in a cookie cutter fashion; the negative is that some kids end up with a "Cadillac" level of service whle others get a whole lot less.
Don't stress out about every detail in an IEP - focus on creating supportive relationships with the people who work with your child. It's amazing how far a kind word will go. Balance that with sane and honest meetings and comments, and you've got the basis of a wonderful educational experience, no matter how the IEP is worded.
