<p>@YZamyatin, an example of a diploma being rescinded for using incomplete/false application info. </p>
<p>As to possible punishment for failing to follow a college’s “all scores” rule when applying, it is true that the college could withdraw your admission if it found out but what it could do and what colleges have thus far done seems to be different. The all scores rules began in March 2009 about a month after College Board announced the adoption of score choice which allowed a student to modify his order for sending scores to prevent any one or more tests from being sent to a college – until that time CB automatically allways sent all SAT and SAT II scores it had for you whenever you wanted to send any one score. A number of elitist colleges, particularly Yale, acted liked spoiled children throwing temper tantrums in response to the CB’s announcement, cried that it was the worst decison CB ever made and deprived them of vital information, and quickly adopted all scores rules. </p>
<p>Since that early flurry of elitist temper tantrums, the following has occurred. Instead of the number of schools requiring all scores increasing, majority, including most of the ivies, decided to allow score choice and a number of schools, including some high ranks like USC and Columbia, have dropped the mandatory all scores rules they adopted in 2009, and the trend has been for more to do that every year, with none adding an all scores rule. The all scores colleges have also struggled to come up with a valid excuse for requiring all scores. The one above from Pomona is I believe Pomona’s fourth version in four years in its attempt to explain the reasoning and if you read it several times you will realize that it is really just gobbledygook. If Pomona and Yale have such an absolute need for all scores, why don’t Princeton and Harvard which accept score choice? Finally, to date there has been no report of any college taking any adverse action against a student for not following an all scores request.</p>
<p>^^drusba - some schools require all scores out of fairness to all applicants. There are many students who cannot afford to take multiple SATs and ACTs. These schools would like to see if the ACT score was achieved after taking it 7 times or if it occurred from one testing. </p>
<p>Even for schools that accept score choice, there may be a question in the application that ask you how many times you have attempted. Not sending in all scores is one thing, while lying on the application is another thing. CommonApp has that question if you choose to self-report test scores.</p>
