"White students in New York City are 10 times as likely as Asian students to have a 504 designation that allows extra time on the specialized high school entrance exams."

"White students are also twice as likely as their black and Hispanic peers to have the designation. Students in poverty are much less likely to have a 504 for extra time.... Students with 504s make up a small percentage of all students who took the specialized school exam with more time. Most students granted extra time are served under laws for students with severe disabilities. Using extra time, students with 504s — and therefore less severe disabilities — performed better than the median test-taker, while students with more severe disabilities performed worse. It sometimes falls to families to request 504s, which are typically granted after an often expensive consultation with a professional.... As the number of students using 504s has ballooned nationally over the last decade, experts have questioned whether the practice has become another way for parents to game standardized tests, including the SAT and ACT."
