When Specialized Assessment Services are Needed, California’s Diagnostic Centers Can Help
Unique to California, the Diagnostic Centers are the California Department of Education’s foremost providers of specialized services and assistance to special education students, their families, and local education agencies (LEAs). The Diagnostic Center Teams are committed to providing a quality service that makes a positive difference for students, their families, and educators.
Established more than 50 years ago, the Diagnostic Centers provide high quality assessments to hundreds of students each year, as well as professional development opportunities for families and educators throughout the state.
California’s three Diagnostic Centers, located in Fremont, Fresno, and Los Angeles, can help LEAs with their most difficult-to-serve special education students ages 2.9 through 22 years. These services are provided at no charge to the LEA or family.
Referrals may be made by the school district when:
- A student is not making progress, even after all local resources have been used.
- A student has complex behavioral and/or learning profiles, in addition to assessment needs that cannot be addressed locally.
Providing Comprehensive, In-Depth Assessments
Dynamic, Transdisciplinary Process
Each assessment is carefully planned and is:
- Highly individualized
- Guided by a set of educationally relevant diagnostic questions
- Designed to support the local district by providing specialized strategies, interventions, and programming options.
- Conducted by a team of experts
Assessment in a Variety of Settings
A student may be assessed in the school, at the Center, or in a combination of both environments.
Parents as Partners
Collaboration with parents is an essential, highly valued, and integral part of the assessment process. Parents assume an active role in the team process through input into the referral questions, participation in portions of the assessment, and extensive interviews with Diagnostic Center assessment staff.
Sharing Assessment Results
After completion of the assessment, Diagnostic Center staff members meet with families and school staff to share assessment findings, including practical teaching strategies and interventions. In addition, the district and parents receive a comprehensive written report.
Linking Assessment Results With Instruction
Consultation and Instructional Support
The Diagnostic Center offers a variety of consultative and/or technical assistance services to school staff to assist with students who have been previously served by the Diagnostic Center.
Regional Workshops, Conference Presentations
Each Diagnostic Center offers state-of-the-art professional development and training programs for both district staff and parents. These presentations and workshops are typically prescheduled through regional workshops and in-services, presentations at major state and national professional conferences, and sponsorship of major conferences on a regional or statewide basis.
