34 C.F.R. § 462.14
(b) If a test that the Secretary has determined is suitable for use in the NRS is substantially revised—for example, by changing its mode of administration, administration procedures, structure, number of items, content specifications, item types, forms, sub-tests, or number of hours between pre- and post-testing—and the test publisher wants the test to continue to be used in the NRS, the test publisher must submit, as provided in § 462.11(j)(4), the substantially revised test or version of the test to the Secretary for review so that the Secretary can determine whether the test continues to be suitable for use in the NRS.
