If the IEP is for any type of disability there is a strict 90 day timeline from referral to placement. Placement is offered at the end of the programming meeting (initial IEP written after evaluation and eligibility determination). Parental signature is required for initial placement, so if you've signed to accept placement (not the same as when you signed to consent to testing/evaluation), then the official process would be considered complete for one year unless a review or revise meeting needs to be held for some reason. Some states have gifted IEPs, but I don't believe they are part of IDEA, so probably don't have to follow the same timelines and rules. My state doesn't have them, so I'm no help there, but the IDEA guidelines are federal and apply in all 50 states.
