Proposals to revise an IEP that occur after a child's annual IEP Team meeting for a school year, may be considered by the entire IEP Team at an IEP Team meeting or by the LEA and parent through documented written agreement, except that the LEA and parent may not agree in writing to revise the child's eligibility status, disability category, or placement to a more restrictive setting outside the LEA.
When proposing to revise the types or amounts of special education or related services through documented written agreement, the LEA shall provide the parent with a written explanation supporting the proposed change including current data and, if relevant, input from the appropriate special education instructor or related service provider.
A proposed revision through documented written agreement shall include signatures from both the LEA and the child's parent to execute the IEP amendment.
If the LEA and parent agree to an amendment, the LEA shall provide the IEP Team with the amendment no later than five (5) business days after a meeting has occurred or documented written agreement has been executed to amend the IEP.
The LEA shall provide the student's parent with a copy of the revised IEP with the amendments incorporated in accordance with Section 3009.8.
