The purpose of this study was to analyze the consequential validity of the 2010
Nationwide Academic Achievement Evaluation for students with visual impairments. A
total of 135 students without visual impairments at a middle school in G metropolitan
city were recruited to participate in this study. Sixty-nine students from one boys'
class and girls' class were randomly assigned to the experimental condition, while
sixty-six students from another boys' class and another girls' class were assigned to
the control condition. Students in the experimental condition (Alternate Group) were
asked to solve 28 social studies questions, including 17 alternate ones, and 23 math
questions, including 13 alternate ones. Students in the control condition (Original Group)
were asked to solve 28 social studies questions and 23 math questions without any
alternate ones in either subject. There was no statistically significant difference
between the two groups in the total score of either subject and subtotal scores of
alternate items and nonalternate items in either subject. There was also no statistically
significant difference between the two groups in various types of alternate items,
respectively, in either subject; an exception was that the Alternate Group scored
significantly lower in the modified social studies questions than did the Original Group.
These results imply the high consequential validity of alternate test items on the 2010
Nationwide Academic Achievement Evaluation for students with visual impairments.
