The Sentence Correction section tests a test taker's knowledge of American English grammar, usage, and style.
Sentence correction items consist of a sentence, all or part of which has been underlined, with five associated answer choices listed below the sentence. The first answer choice is exactly the same as the underlined portion of the sentence. The remaining four answer choices contain different phrasings of the underlined portion of the sentence. The test taker is instructed to choose the first answer choice if there is no flaw with that phrasing of the sentence. If there is a flaw with the original phrasing of the sentence, the test taker is instructed to choose the best of the four remaining answer choices.[5]
Sentence Correction questions are designed to measure a test taker's proficiency in three areas: correct expression, effective expression, and proper diction. [5] Correct expression refers to the grammar and structure of the sentence. Effective Expression refers to the clarity and concision used to express the idea. Proper Diction refers to the suitability and accuracy of the chosen words in reference to the dictionary meaning of the words and the context in which the words are presented.[5]
