Evaluations by a Teacher for Blind/Visually Impaired and Orientation and Mobility Instructor are required when meeting eligibility requirements for services and determining the needs of your student.

Evaluations performed by a Certified Teacher for Blind/Visually Impaired

Functional Vision Evaluation

The Functional Vision Evaluation is designed by the TBVI according to your student's learning materials, school activities and specific visual diagnosis, often including:
  • Observations of your student's visual behaviors within the educational environment and familiar routines
  • Informal assessment of acuity, contrast sensitivity, visual fields, color vision and more using a set of activities presented by the Teacher for Blind/Visually Impaired
  • Interpretation of ophthalmological reports (must be on file for eligibility)
  • Interviews with staff and/or parents about the students visual behaviors

Learning Media Evaluation

The Learning Media Evaluation is used to determine the most effective sensory channels for instruction as well as the appropriate design of learning materials (braille, large print, contrast, etc.)  Your TBVI will consider the following during a Learning Media Evaluation.
  • How does the student appear to access and/or participate in school activities:
    • Visually
    • Auditorally
    • By touch and tactile exploration and/or feedback
    • Using one sensory channel at a time
    • Using multiple sensory channels
    • Effective print and picture sizes
    • Effective colors and contrast for the individual student
