Whether a typo or purposeful, this absolutely needs to be corrected. I would email the IEP team now and ask for an amendment. If they prefer to wait until the annual meeting/renewal, at least get them to acknowledge the mistake in your email correspondence with them and that it will be corrected on the next IEP document. One exception would be if they are doing a re-evaluation and do not plan to set forth previous results in the new IEP document under the argument that they are no longer "present levels" (this has, unfortunately, been successful in some cases). In that scenario, you would definitely want the current IEP changed now.
