(a) A written report of a full individual and initial evaluation of a student for purposes of special education services shall be completed as follows, except as otherwise provided by this section:
(1) not later than the 45th school day following the date on which the school district, in accordance with 20 U.S.C. § 1414(a), as amended, receives written consent for the evaluation, signed by the student’s parent or legal guardian, except that if a student has been absent from school during that period on three or more days, that period must be extended by a number of school days equal to the number of school days during that period on which the student has been absent; or
(2) for students under five years of age by September 1 of the school year and not enrolled in public school and for students enrolled in a private or home school setting, not later than the 45th school day following the date on which the school district receives written consent for the evaluation, signed by a student’s parent or legal guardian.
(a-1) If a school district receives written consent signed by a student’s parent or legal guardian for a full individual and initial evaluation of a student at least 35 but less than 45 school days before the last instructional day of the school year, the evaluation must be completed and the written report of the evaluation must be provided to the parent or legal guardian not later than June 30 of that year. The student’s admission, review, and dismissal committee shall meet not later than the 15th school day of the following school year to consider the evaluation. If a district receives written consent signed by a student’s parent or legal guardian less than 35 school days before the last instructional day of the school year or if the district receives the written consent at least 35 but less than 45 school days before the last instructional day of the school year but the student is absent from school during that period on three or more days, Subsection (a)(1) applies to the date the written report of the full individual and initial evaluation is required.

(a-2) For purposes of this section, “school day” does not include a day that falls after the last instructional day of the spring school term and before the first instructional day of the subsequent fall school term. The commissioner by rule may determine days during which year-round schools are recessed that, consistent with this subsection, are not considered to be school days for purposes of this section.
(a-3) Subsection (a) does not impair any rights of an infant or toddler with a disability who is receiving early intervention services in accordance with 20 U.S.C. § 1431.
(b) The evaluation shall be conducted using procedures that are appropriate for the student’s most proficient method of communication.
(c) If a parent or legal guardian makes a written request to a school district’s director of special education services or to a district administrative employee for a full individual and initial evaluation of a student, the district shall, not later than the 15th school day after the date the district receives the request:
(1) provide an opportunity for the parent or legal guardian to give written consent for the evaluation; or
(2) refuse to provide the evaluation and provide the parent or legal guardian with notice of procedural safeguards under 20 U.S.C. § 1415(b).
