As Northern Virginia became home to more immigrant families in recent decades, Fairfax County officials say they started programs to teach English as a second language at every school – about 200 of them. Except one.
The holdout was the region’s hallowed magnet school, Thomas Jefferson High School for Science and Technology, where many assumed that steep admissions standards rendered such a program for English language learners unnecessary.
But next year, at the behest of the school’s teachers, Thomas Jefferson – often called TJ – plans to hire its first instructor to cater to a growing number of students who thrive in math and science classes but sometimes struggle with English.
The decision to hire the half-time teacher has reinvigorated a debate about TJ’s mission – namely, how heavily the school’s admissions policy should favor math and science standouts over well-rounded applicants with superior reading and writing abilities.
