What is a Teacher of the Visually Impaired?

A Teacher of the Visually Impaired (TVI) has received specialized training in the education of students with visual impairments, skills specific to visual impairment, and accessibility needs. They provide services for students with visual impairments ranging from low vision to blindness. These services can include specially designed instruction, preparation of accessible materials, and training for school staff on student needs.


A teacher of the visually impaired is a certificated teacher with an endorsement in special education and additional training from an accredited college or university in the education of students with visual impairments. Many TVIs have a master’s degree in special education.


We empower students with visual impairments to lead their most independent lives through access to education and their environment.

A TVI teaches a series of subjects known as the Expanded Core Curriculum (ECC). The ECC is a set of areas in which students may require specially designed instruction due to their visual impairment. Some areas of the ECC are

  • Compensatory skills (braille, reading tactile graphics, abacus, large print access, use of magnifiers)
  • Assistive technology (screenreading software, magnification software, digital magnification, other digital and analog tools)
  • Self-determination and self-advocacy
  • Sensory efficiency (using hearing, touch, smell, taste, and any functional vision effectively)
  • Independent living skills (non-visual and low vision strategies for daily living tasks)

The TVI works closely with other members of a student’s team to make sure that vision needs are met when planning programming. For example, a TVI may collaborate with the speech language pathologist in choosing tactile objects or visual icons for augmentative and alternative communication (AAC).

What is an Orientation and Mobility Specialist?

Certified Orientation & Mobility (O&M) Specialists have received specialized training to teach students who are blind or who have low vision the techniques needed to determine their position in space and safely navigate their environment. The O&M Specialist's training emphasizes the acquisition of knowledge and skills necessary for teaching safe and efficient independent travel within realistic learning environments. O&M Specialists collaborate with classroom teachers, parents, and other service providers who are involved in the students’ educational program. Students must meet criteria for Vision Services to qualify for O&M Services. 


O&M Specialists will have a Master’s Degree in Orientation & Mobility. Certified O&M Specialists (COMS) are certified through the Academy for Certification of Vision Rehabilitation & Education Professionals, or ACVREP, & ongoing professional development in O&M is required to maintain certification.

  • Concept Development, e.g. body awareness, directional/positional awareness
