SAN DIEGO, Calif. – Syrian refugees are pouring into schools across the country, from Chicago to San Diego to New Haven, Connecticut.

State Department figures estimate that roughly 80 percent of the 11,000 Syrian refugees who arrived in the United States over the last year are children, which equates to about 8,800 students with limited English and severe trauma, Fox News reports.

“The truth is, a lot of them have seen some pretty nasty stuff,” said Eyal Bergman, family engagement officer for the Cajon Valley Union School District just outside of San Diego. “But I also see incredible resilience.”

The El Cajon district took in 76 Syrian refugee students in the first week of school, the latest in a long line of refugees from the Middle East that started with Chaldean Christians fleeing Iraq in the 1970s, according to the news site.

“I’ve had students tell me that maybe some of their family members passed away,” Juanita Chavez, a second-grade teacher, told Fox News. “But I think a lot of them just want to focus on here, on learning. A lot of them don’t focus on the negative things that have happened to them.”

The situation forces district officials to devote a lot of resources to refugee students, including “newcomer” classes to learn English, counselors to help refugees with trauma, hiring Arabic-speaking staff to host “parent academy” lessons on helping their children learn English, one-on-one orientations to help parents understand how the school system works, and other efforts.

The influx of Syrian refugees stems from President Obama’s promise to resettle thousands from their war-torn country in America, a move Democratic presidential candidate Hillary has said she would expand to 65,000 refugees if elected.

Republican presidential candidate Donald Trump, meanwhile, describes the flood of refugees as the “greatest Trojan horse of all time” and has criticized the process for inadequately vetting for potential terrorists, who have snuck into other countries by posing as refugees.

In Canada, now home to 31,919 Syrian refugees, government officials are scrambling to find funds to cover special services for their new residents, a large portion of which are school children, CBC reports.

“Many of the refugees had large numbers of children and that was not completely anticipated in the beginning,” John McCallum, Citizenship and Education Minister, told the news site.

“We know roughly how many families we’ll be getting but we never seem to know the family size,” said Ian Wishart, Manitoba’s Minister of Education.

McCallum said the Canadian government is funding support programs for refugees during their first year in the country, and may increase spending on education for language instructors and programs.

“After that we hope that they would have a job,” he said.

Winnipeg School Division spokeswoman Radean Carter said the school district is asking the government for extra money to hire more language instructors because the $600,000 it received last year to accommodate 170 Syrian students isn’t enough.

“These resources are fully employed and finding more qualified (English as an additional language) teachers and support workers is becoming a challenge,” Carter said.  “While we are expecting additional refugee students into our division this school year, we have not had any numbers or timing confirmed, nor any funding announced.”
