(d) The ARD committee shall make its decisions regarding students referred for a full and individual initial evaluation within 30 calendar days from the date of the completion of the written full and individual initial evaluation report. If the 30th day falls during the summer and school is not in session, the ARD committee shall have until the first day of classes in the fall to finalize decisions concerning the initial eligibility determination, the IEP, and placement, unless the full and individual initial evaluation indicates that the student will need extended school year (ESY) services during that summer.
