KENNETT SQUARE, Pa. — The cheerful sign outside Jane Cornell’s summer school classroom in Pennsylvania’s wealthiest county reads ‘‘Welcome’’ and ‘‘Bienvenidos’’ in polished handwriting.
Inside, giggling grade-schoolers who mostly come from homes where Spanish is the primary language worked on story-telling with a tale about a crocodile going to the dentist. This poster and classroom at the Mary D. Lang Kindergarten Center are a subtle representation of America’s changing school demographics.
For the first time ever, US public schools are projected to have more minority students than non-Hispanic whites, a shift largely fueled by growth in the number of Hispanic children.
Non-Hispanic white students are still expected to be the largest racial group in the public schools this year at 49.8 percent. But according to the National Center for Education Statistics, minority students, when added together, will now make up the majority.
About one-quarter of the minority students are Hispanic, 15 percent are black, and 5 percent are Asian and Pacific Islanders. Biracial students and Native Americans make up a smaller share of the minority student population.
The shift brings new academic realities, such as the need for more English language instruction, and cultural ones, such as changing school lunch menus to reflect students’ tastes.
But it also brings up some complex societal questions that often fall to school systems to address, including issues of immigration, poverty, diversity, and inequity.
As the population becomes more diverse, schools are becoming more racially divided.
The result, at times, is racial tension.
In Louisiana in July, Jefferson Parish public school administrators reached an agreement with the federal government to end an investigation into discrimination against English language learners. In May, police had to be called to help break up a fight between Hispanic and black students at a school in Streamwood, Ill., a Chicago suburb, after a racially-based lunchroom brawl got out of control.
Issues of race and ethnicity in schools also can be more subtle.
In Pennsylvania’s Kennett Consolidated School District, superintendent Barry Tomasetti described parents who opt to send their kids to private schools in Delaware after touring diverse classrooms. Other families, he said, seek out the district’s diverse schools ‘‘because they realize it’s not a homogenous world out there.’’
The changes in the district from mostly middle-to-upper class white to about 40 percent Hispanic were in part driven by workers migrating from Mexico and other countries to work the mushroom farms.
‘‘We like our diversity,’’ Tomasetti said, even as he acknowledged the cost. He has had to hire English language instructors and translators for parent-teacher conferences. He has cobbled money together to provide summer school for many young English language learners who need extra reading and math support.
The new minority-majority status of America’s schools mirrors a change that is coming for the nation as a whole. The Census Bureau estimates that the country’s population also will have more minorities than whites for the first time in 2043, a result of higher birth rates among Hispanics and a stagnating or declining birth rate among blacks, whites, and Asians.
Even as the population becomes more diverse, schools are becoming more racially divided, reflecting US housing patterns.
The disparities are evident even in the youngest of black, Hispanic, and Native American children, who on average enter kindergarten academically behind their white and Asian peers. They are more likely to attend failing schools and face harsher school discipline.
Later, they have lower standardized test scores, on average, fewer opportunities to take advanced classes, and lower graduation rates.
Education Secretary Arne Duncan said the country needs to make sure all students ‘‘have an opportunity to have a world-class education, to do extraordinarily well.’’
