Summary

Accommodation

The purpose of this study was to examine the effects of extra time, at 150% (or 1.5 times) the standard time allotted for completion of the Graduate Record Examination General Test.

Participants

The participants included a national (U.S.) sample of 15,948 postsecondary students who chose to take an additional test after a standard administration of the Graduate Record Examination. Three subsets of participants were compared: low ability, medium ability, and high ability; however, no disabilities were reported for participants. 

Dependent Variable

The verbal and quantitative sections of the Graduate Record Examination General Test comprised the dependent variable measured for the impact of being administered with standard time limits and at 1.5 times the standard time allotted.

Findings

Extra time added about 7 points to verbal scores and 7 points to quantitative scores. The accommodation appeared to have a greater impact on the quantitative scores of lower ability examinees.
