Columbia, Yale, Cornell, U Penn and Dartmouth test-optional.

While there are now 6 Ivy league schools that are test-optional, that doesn't mean they are not being considered during the application review process. The exception is Cornell's Agricultural and Architecture programs that "do not require" the SAT or ACT. My opinion is that if you have the ability to take either the SAT, ACT, or SAT II subject tests, you should and you should submit the scores if you get a high score commensurate with your grades, course rigor, and research. If you get lesser, scores, do not submit them. During the next application cycle, all the Ivys will get more applications because more students will apply now that stats are optional. However, if you are competing against similar candidates and have submitted excellent stats, then you have increased the reader's belief that you might succeed at their campus more than the others since you have something tangible like a test score. While some argue that there is no correlation between stats and a student's ability to academically succeed, many others think they are positively correlated and meaningful. That's a different argument than whether or not they are fair, equitable, or hurt disadvantaged applicants from lesser zip codes or poorer backgrounds. If you have a great reason why you can't take the tests, then I would make sure the school knows about this. Otherwise, do whatever you feel necessary to stack the odds in your favor. (the last thing make sure you read each schools policy about taking the TOEFL exam). Best of luck.
