IDEA requires that the EC in making the determination of a speech-language impairment consider how the disability affects the progress and involvement of the student in the general curriculum.
The EC must consider each student individually to determine how the student's disability adversely affects educational performance. Documentation of adverse effects on educational performance can be gathered from a thorough assessment of communication skills. The assessment must include student, parent, and teacher input. An assessment of a student's ability to communicate, rather than isolated skill assessment, will provide information on how the impairment affects the student.
The following examples may be considered when determining how the student's ability to communicate may adversely impact educational performance:. Sound errors, voice quality, or fluency disorders inhibit the student from reading orally in class, speaking in front of the class, or being understood by teachers, peers, or family members.
Sound errors, voice quality, or fluency disorders embarrass the student. Peer relationships suffer as a result, or peers may make fun of the student.
