California Code, Education Code - EDC § 99160.5

(a) A test agency shall immediately initiate an investigation upon learning of a complaint or a notice of inadequate or improper test conditions relating to an administration of an Advanced Placement test.  In order to expedite the investigation and ensure a timely resolution, the school in charge of the test site shall cooperate with the test agency's investigation by providing information requested by the test agency within five business days.  If, upon completing the investigation, the test agency determines that the inadequate or improper test conditions will prevent it from reporting valid test scores, the test agency shall notify the school in charge of the test site of the decision within two business days.  Upon notification from the test agency that the test agency has determined that the inadequate or improper test conditions will prevent it from reporting valid test scores, the school in charge of the test site shall notify the affected test subjects of the decision within two business days.  The school in charge of the test site shall provide all affected test subjects with at least five business days' prior notice of an opportunity to retest.  That retest shall be administered within 30 calendar days of the completion of the investigation.

(b) Proctors administering an Advanced Placement test shall create a seating chart, including the seat location of each test subject, for each Advanced Placement test administered at the test site.  The test agency shall provide seating chart templates for use by each test site.  The school in charge of the test site shall retain and preserve each seating chart created pursuant to this subdivision for at least one year after the administration of the Advanced Placement test to which that seating chart applies.  The school in charge of the test site shall submit these seating charts to the test agency upon its request to assist with its investigation of a complaint or notice of inadequate or improper test conditions.
