Relationships among testing medium, test performance, and testing time of high school students who are visually impaired

This study compared the test scores and time required by high school students who are blind, sighted, or have low vision to complete tests administered in written and oral formats. The quantitative results showed that the blind students performed better on multiple-choice tests in braille and needed more time while taking tests in braille. The interviews revealed inconsistent relationships between the students' preferred media and performance.
