This document discusses testing writing ability. It outlines five general components of writing: content, form, grammar, style, and mechanics. It compares composition tests and objective tests, noting advantages and criticisms of each. The current moderate position is that well-constructed objective tests correlate highly with writing ability, and composition tests can also be made reliable. Specific writing elements like grammar, style, and organization can be objectively tested through items like error recognition and sentence completion. The mechanics of writing can also be objectively tested. Improving composition tests involves taking multiple samples, clear prompts, anonymous scoring, and establishing standards before marking papers.
