Starting in March 2005, the SAT, taken annually by more than 1.4 million college-bound students, will undergo its most significant change since 1994, when the College Board, which sponsors the test, first allowed calculators into test rooms, added open-ended math questions, and eliminated antonyms and added more critical-reading passages in the verbal section. Now, in addition to math and verbal (renamed Critical Reading) sections, the SAT will include a writing section comprising a 25-minute essay question and questions that will require students to identify sentence errors and improve sentences and paragraphs. The revised SAT and its essay question will help because the demands for writing in college are way beyond what most high schools now require. There are also other changes. Testing time will increase from three hours to three hours and forty-five minutes. The classic SAT maximum score of 1600 will become obsolete, replaced by a maximum of 2400. Some observers, including teachers, have concerns about the new SAT. The revised test's tilt toward English could hurt students who are better at math and those who speak English as a second language.
