Referral of students for a full and individual initial evaluation for possible special education services shall be a part of the district's overall, general education referral or screening system. Prior to referral, students experiencing difficulty in the general classroom should be considered for all support services available to all students, such as tutorial, remedial, compensatory, and other services. If the student continues to experience difficulty in the general classroom after the provision of interventions, district personnel must refer the student for a full and individual initial evaluation. This referral for a full and individual initial evaluation may be initiated by school personnel, the student's parents or legal guardian, or another person involved in the education or care of the student. The referral for a full and individual initial evaluation must be completed in accordance with Texas Education Code, §29.004, related to the 60 calendar day time line.
