美國的大學入學考試有兩種：SAT和ACT。有的學生喜歡選擇SAT考試，有的學生喜歡選擇ACT考試。具體這兩種考試的特點比較分析、各適合哪些孩子，我們星期天留學資訊平台的微信群裏，請在洛杉磯和北京都辦有留美培訓班的陳老師做過講座，這樣的講座我們在微信群裏還會請來自不同培訓機構的名師來講，因為不斷有新入群的家長和學生提出需求。
那麽SAT和ACT的分數是怎麽換算的，我們先看一下舊SAT和ACT的換算表：
| SAT (with writing test addition) | ACT composite score |
| 2400 | 36 |
| 2340 | 35 |
| 2280 | 34 |
| 2220 | 33 |
| 2160 | 32 |
| 2100 | 31 |
| 2040 | 30 |
| 1980 | 29 |
| 1920 | 28 |
| 1860 | 27 |
| 1800 | 26 |
| 1740 | 25 |
| 1680 | 24 |
| 1620 | 23 |
| 1560 | 22 |
| 1500 | 21 |
| 1440 | 20 |
| 1380 | 19 |
| 1320 | 18 |
| 1260 | 17 |
| 1200 | 16 |
| 1140 | 15 |
| 1080 | 14 |
| 1020 | 13 |
| 9600 | 12 |
| 900 | 11 |
新的SAT推出後，我一直關心新的SAT和ACT的換算關係，今天我看到在College Board的官網上輸入ACT，立刻就出現Comparing SAT® and ACT® Scores的標題，點擊進去可以看到How to Compare Scores怎樣比較分數
1，The most appropriate way to compare SAT and ACT scores is through a concordance table based on research by the makers of each test.
比較SAT和ACT分數的最合適的方法是通過各自考試機構對每個測試的研究得出的一致性表。
2，College admission officers use these tables to understand how students of comparable ability would score on the two exams. The tables clearly show which SAT scores are comparable to which ACT scores.
大學招生官通過這個表來比較學生們在兩個考試分數上各自顯示的能力。這個表清晰地給出了SAT對應於哪個ACT分數。
3，The table below compares Critical Reading and Mathematics sections, and the table on the back of this flyer includes the Writing section.
這個分數對比表還列出了閱讀、數學以及寫作的分項對應分數對比
4，We recommend that counselors use concordance tables to compare SAT and ACT scores. Percentile rankings are not a technically sound (or “appropriate”) way to compare scores across different tests because the rankings are applicable only to the administration of a particular exam to a specific group of examinees. Not only is comparing percentiles inaccurate, it can lead to improper testing guidance.
我們建議顧問使用一致性表來比較SAT和ACT分數。百分位的排名並不適合比較在不同測試上的分數,因為排名隻適用於特定的考試管理的一個特定群體的考生。不僅是比較百分位數不準確，而且可能導致不當測試指導。也就是說這兩種考試不能給出精確比較。
而在ACT的官網也出現這樣的話
ACT官方：
The ACT and SAT are different tests that measure similar but distinct constructs. The ACT measures achievement related to high school curricula, while the SAT measures general verbal and quantitative reasoning.
ACT and the College Board have completed a concordance study that is designed to examine the relationship between two scores on the ACT and SAT. These concordance tables do not equate scores, but rather provide a tool for finding comparable scores.
ACT官方的意思大致是：ACT與SAT是不同的兩種考試，測試的方法相似，但是結構不同，殊途同歸。對於兩種考試的定義，簡單來說一個是針對高中課程掌握程度的考察，一個是對邏輯推理能力的測評，最終目的都是為了評測學生是否具備了進入大學接受高等教育的學習能力。
