Starting in January 2016, HiSET is changing the Writing exam.
Switch Freely Between Parts
While the test is still 120 minutes total, they will now allow the student to switch back and forth between the multiple-choice part and the essay. For most test-takers this will allow more time for the essay because the majority of people finish the first part with time left over. I encourage everyone to take advantage of this extra time due to the other major change. . .
Essays in Context
The essay prompt is now in the context of two opposing-sides essays. The test-taker must read the two essays and write a persuasive essay defending their side while acknowledging the opposition and citing the original texts.
