As much as possible, answers to test questions should be written on the test itself. All tests with questions which require answers that can reasonably be expected to run for half a page or less should provide space on the test proper for the student to write the answer on the test. Only for questions with answers that can reasonably be expected to run for more than half a page could test makers be allowed to require students to write their answers for such questions on separate paper. Otherwise, unnecessary time demands, difficulty and complexity is introduced during the critical testing period by requiring students to write every answer on a separate sheet of paper and coming up with their own method of formatting and referencing their answers to the questions on the test sheet. Additionally, writing answers on a test would help students more easily catch any answers they may have accidentally skipped over.
