(d) Conducting an IEP Team meeting without a parent in attendance. A meeting may be conducted without a parent in attendance if the public agency is unable to convince the parents that they should attend. In this case, the public agency must keep a record of its attempts to arrange a mutually agreed on time and place, such as—
(1) Detailed records of telephone calls made or attempted and the results of those calls;
(2) Copies of correspondence sent to the parents and any responses received; and
(3) Detailed records of visits made to the parent’s home or place of employment and the results of those visits.
