Diversity lags at highly selective Thomas Jefferson High School

Jay Matthews:

When I first heard complaints that the admissions process at Thomas Jefferson High School for Science and Technology had gone soft, I guessed that the cause of the unrest was an effort by our nation’s most selective school to become more diverse.
Of the freshmen who entered the Fairfax County public school in 2010, only 13 were Hispanic and four were black. That amounted to 3.5 percent of the class, even though 52 Hispanic and 29 black applicants had academic records good enough to survive the first cut. I assumed that the school, reacting to those numbers, had begun to admit more Hispanic and black students, which in turn might be the source of criticism for a downturn in this year’s freshman grades.
I was wrong. More freshmen this year needed remediation, but growing ethnic diversity cannot be the reason.
