自从SAT改革以后，写作部分被分拆：essay单列，语法部分更名为Writing and Language Test。此外，语法测试将融入阅读文章考察。也就是说，目前SAT语法的句子挑错，句子改进和文章改进题三种题型，将合并为文章改进题一种题型。官方原文如下：
Students can demonstrate college and career readiness proficiency in revising and editing a range of texts in a variety of content areas, both academic and career related, for expression of ideas and for conformity to the conventions of standard written English grammar, usage, and punctuation。
详细说来，改革后的sat语法考察四个方面：
1.词语的正确使用
动词(单复数，时态，语态，语气)，代词(人称，指代不清，所有格)，名词(一致)，介词(固定搭配)易混词，比较结构。
2.句子结构修改
句子连接，句子残缺，主从句，平行结构，修饰语位置错误
3.文意表达(expression of ideas)
①行文：提出论点，论据支持，主题相关度和数据信息(proposition，support，focus，quantitative information)
②结构：句子先后顺序，导入，结尾和衔接。(Logical sequence, Introductions,
conclusions, and transitions)
③有效性：
准确：用词的准确和恰当
简洁：用词的不赘余(避免wordiness和redundancy)
新增考点：
根据文章需要，保持风格，语调和修辞的合适(style，tone and syntax)
4.标点符号(punctuation)
句末标点(End-of-sentence punctuation);
句中标点(Within-sentence punctuation);
新增考点：
所有格名词和代词(Possessive nouns and pronouns);
词间标点(Items in a series);
非限制和附加成分(Nonrestrictive and parenthetical elements);
不必要标点(Unnecessary punctuation)
