Philosophy

The 16 Visual Behaviors and Compensatory Skills

The Perkins CVI Protocol offers a flexible approach to assessing all students with CVI, and is rooted in Perkins’ framework for understanding CVI: 16 Visual Behaviors and Compensatory Skills. This foundational philosophy encourages assessment of how a student is impacted by CVI and the strategies they use to access their world.

The Perkins CVI Protocol is intended to be conducted by a teacher of students with visual impairments (TVI), ideally with an understanding of CVI. We know that an assessor with a background in CVI may not always be available, so The Perkins CVI Protocol includes a comprehensive introduction to the 16 Visual Behaviors and Compensatory Skills.

Perkins recommends taking the companion course to the Perkins CVI Protocol, “Assessing students with CVI,” on PerkinsAcademy.org, free for a limited time to qualified educators who download the CVI Protocol.

Process

The Workbook

The Workbook is an editable, customizable format of The Perkins CVI Protocol. It offers guidance for conducting an educational CVI assessment and is intended to be completed step-by-step, but also encourages interaction with space and flexibility for taking notes and completing report templates directly in the documents. Assessors are encouraged to tailor components, questions, suggestions, etc. to the needs of each student.

The Workbook provides you with guides, templates, and resources, such as:

  • HIPAA-compliant intake form
  • Parent and team interview questions
  • Concrete ideas for observations and direct assessments
  • CVI evaluation report template
  • Robust list of CVI recommendations

Structured

The Perkins CVI Protocol guides a TVI through the essential steps of conducting a thorough CVI assessment, including:

  • Preparing & gathering information
  • Conducting interviews
  • Observing & assessing
  • Writing the CVI evaluation report
  • Choosing recommendations for IEP
  • Sharing assessment findings

Tried and Tested

The current version of The Perkins CVI Protocol was developed through an iterative, collaborative process:

  • 7 trials between 2022-2024
  • Feedback collected from hundreds of participants (TVIs, clinicians, parents)
  • Improvements made to workflow, usability, & design based on user feedback
  • Future iterations of The Protocol (e.g., digital version) will continue to evolve with our understanding of CVI

Holistic

The Perkins CVI Protocol is a student-centered, inclusive tool intended for assessing all students regardless of age or CVI diagnosis status:

  • Applies to students ages 0-22
  • Provides guidance for students diagnosed with or suspected of having CVI
  • Encourages customization to accommodate students’ needs, abilities, and age
  • Considers students’ likes, dislikes, motivations, & unique impacts of CVI
CVI Protocol Trial Participant TVI

“The CVI Protocol involves a child’s caregivers and team members. It uses parental input and observation to make recommendations. It lends itself to educating families as well.”

CVI Protocol Trial Participant Medical Professional

“This is the first well rounded and well researched method of not only assessing but working out how CVI can be incorporated into the child’s existing goals.”

CVI Protocol Trial Participant TVI

“The CVI protocol provided a means to thoroughly assess a student’s visual access/challenges and provide appropriate steps for support/access. It also enabled the assessment of those students with suspected CVI to support parents in discussing the diagnosis further with medical professionals.”
