Our Assessment Program

The Assessment Program at the California School for the Blind (CSB) is a statewide resource of professionals who have specific expertise in the education of children and young adults who are blind, visually impaired, or deaf-blind. We provide the following services:

  • Parent and Staff Consultation
  • Student Assessment
  • Professional Development

There are two models of student assessment:

  • Center Assessment
  • Field Observation/Consultation

Referral questions and a careful consideration of the characteristics and needs of the individual student determine which model is appropriate. The evaluations conducted by the CSB Assessment Center team do not take the place of initial or triennial Individualized Education Program (IEP) evaluations or Independent Educational Evaluations (IEEs). Our assessments are not a part of the IEP process, and our team does not participate in IEP meetings. Our recommendations are made for IEP teams, including families, to consider for IEPs.


  • Has a visual impairment which, even with best correction, adversely affects educational performance.
  • Has unresolved educational concerns following thorough district assessment.

Our Focus

Areas of the Core and Expanded Core Curriculum form the basis for our service. This may include:

  • Functional vision
  • Speech and Language
  • Cognitive Development
  • Academic achievement
  • Learning/reading media
  • Assistive technology/Augmentative alternative communication
  • Technology needs
  • Orientation and Mobility
  • Recreation and leisure skills
  • Independent Living Skills
  • Social-emotional functioning
  • Self-determination and advocacy

Center Assessment

Referral questions are addressed over three to five days through direct assessment, observations, and parent interviews. Results and recommendations are discussed in a collaborative conference with parents and district professionals. A comprehensive written report completes the process.
This format is appropriate for students who can respond to formal testing on the CSB campus. An apartment is available for family use.

Field Observation/Consultation

Referral questions are addressed during one to two days of direct observation, a parent meeting in the home setting, and discussion with educational team members. A collaborative conference with parents and educational professionals is followed by a written report.
This format is appropriate for students whose strengths and needs are best demonstrated through interactions within their familiar home and school environments.

Consultation and Professional Development

Our staff is available for consultation, group workshops, or trainings to support district efforts and required assessments to provide the best possible education for students who are blind or visually impaired in California. Please review the Consulation FAQs where we have strived to answer many common questions regarding comprehensive student assessment.

If you still have specific questions after reading the Consultation FAQ or are requesting professional development, please fill out the Consult/Training Request and Information External link opens in new window or tab. (Google Form) form, and we will contact you shortly.

Application Information

Please contact the center for an application packet at (If you are only seeking a low vision exam or an Assistive Technology Assessment please contact those departments.) If IEP team members, including families, would like to request an assessment, we require that families and Local Educational Agencies (LEAs) provide access to the relevant records (including Functional Vision Assessment/Learning Media Assessment (FVA/LMA) and triennial evaluation from within the last 3 years), current learning environment, and staff for potential reviews, observations, and dynamic assessments. We require all IEP team members, including a district representative, to attend a collaborative conference to review the evaluation results and recommendations. The collaborative conference is not a IEP meeting.
