Philosophy:   In accordance with federal and state guidelines, DISD provides a full range of academic, behavioral, emotional and related evaluation services. Evaluations are conducted by qualified staff using the most current, appropriate norm and criterion referenced assessment instruments.  DISD assessment staff assist campus with referrals. DISD assessment staff can evaluate for dyslexia, 504 evaluations, and conduct full individual evaluations (FIE) for special education eligibility determination.  
Goals:   To provide a comprehensive, timely, and relevant written report of an evaluation that addresses the referral question as well as subsequent evaluation issue discovered during the evaluation and that will assist the parents and instructional team in planning for the student’s educational needs. To maintain a high level of professional development in all required continuing education categories.
The DISD Assessment team consists of Educational Diagnosticians, Licensed Specialists in School Psychology, and a Licensed Professional Counselor.  The team coordinates all evaluations for students suspected of having a disability or in need of a reevaluation for special education services, other than students who are only suspected of having a speech impairment.

Process:   All initial referrals to the assessment team are via the campus referral team. Students participate in the Student Intervention Team and, when appropriate, a multi-tiered system of supports (MTSS) or response to intervention (RTI) process prior to a referral. The referral team determines the referral question (and thus, the nature of the evaluation, e.g. whether it is a dyslexia evaluation or a Full Individual Evaluation for special education) and forwards it to the assessment department.  An assessment team leader (ATL) is assigned – this can be either an LSSP, SLP or diagnostician.  While dyslexia and 504 evaluations are conducted primarily by a sole evaluator with input from teachers, all FIEs are conducted by a multi-disciplinary team (to include general and special education teachers and other relevant related service providers, such as an OT, or nurse).
DISD assessment staff maintain the highest standards in ongoing professional development requirements.  Staff regularly attend professional development focused on evaluation techniques, interpretation methodology, report writing and implementation strategy.
