15% is several times higher than the overall RD admit rate, which was around 4.5% last year and is on pace to be closer to 4% this year. It’s also higher than the admit rate for applicants within any of the stat ranges Stanford lists on the admissions profile page of their website. Acceptance is obviously far from certain, but getting deferred also shouldn’t be dismissed as a polite rejection with “less than 1% chance of an admittance”.</p>
