Assessment Resources

This section provides resources about different assessment tools and when they might be most helpful. This can be complex because there is no single assessment tool for students with visual impairments. Instead, there are various tools specific to different needs - some for skills, some for cognitive assessment, some for other needs.

It is crucial to remember that the vast majority of assessment tools are designed for students who are sighted, and assessment tools should not penalize students with visual impairments for not being able to perform tasks that require vision.

Most teachers use a combination of formal and informal assessment tools. Some are designed specifically for students with visual impairments, while others are adapted or modified.
