Each local school district shall make an initial determination of whether a student has an eligibility ruling of speech-language impairment that qualifies under the Individuals with Disabilities Education Act (IDEA) to receive services and funding under the provisions of the IDEA before proceeding to the development of a plan for each speech-language impaired student eligible for educational services or equipment, or both, under Sections 37-23-1 through 37-23-150. Furthermore, these provisions do not prohibit a parent or legal guardian of a student who has an eligibility ruling of speech-language impairment, at any time, from choosing the option of a Mississippi Speech-Language Therapy Scholarship which would allow the student to attend another nonpublic special purpose school.
