In 2006, ETS announced plans to enact significant changes in the format of the GRE. Planned changes for the revised GRE included a longer testing time, a departure from computer-adaptive testing, a new grading scale, and an enhanced focus on reasoning skills and critical thinking for both the quantitative and qualitative sections.
On April 2, 2007, ETS announced the decision to cancel plans for revising the GRE. The announcement cited concerns over the ability to provide clear and equal access to the new test after the planned changes as an explanation for the cancellation. The ETS stated, however, that they do plan "to implement many of the planned test content improvements in the future", although specific details regarding those changes have not yet been announced.
Changes to the GRE took effect on November 1, 2007, as ETS started to include new types of questions in the exam. The changes mostly center on "fill in the blank" type answers for both the mathematics and vocabulary sections that require the test-taker to fill in the blank directly, without being able to choose from a multiple choice list of answers. ETS currently plans to introduce two of these new types of questions in each quantitative or vocabulary section, while the majority of questions will be presented in the regular format.
On January 2008, the Reading Comprehension within the verbal sections has been reformatted, passages' "line numbers will be replaced with highlighting when necessary in order to focus the test taker on specific information in the passage" to "help students more easily find the pertinent information in reading passages."
In December 2009, ETS announced plans to move forward with significant revisions to the GRE in 2011. Changes include a new 130-170 scoring scale, the elimination of certain question types such as antonyms and analogies, the addition of an online calculator, and the elimination of the CAT format of question-by-question adjustment.
