Editor's note: Given the ups and downs of Chinese church-state relations, we have changed names and dropped cities that would give potential persecutors geographic hints.

(WNS)--In China, when 7th-grader Lei became depressed and unresponsive, his parents wondered what had happened. He hardly spoke when they picked him up from his public boarding school on Saturdays and dropped him off again on Sundays. It took months before Lei told his parents what was wrong: His grades were slipping, even though he studied almost every waking hour and often barely slept.

Like any student falling behind in China—where grades are based solely on test scores—Lei knew that poor grades would affect his prospects for high school, college, and a future career. Disturbed, his parents began inquiring about U.S. high schools.

With only one main education track in China—a secular public school system—a growing number of parents are looking for alternatives for their children. Like Lei's parents, some believe the stress of China's test-driven education system is too high, and parents with only one child are able to pay for an alternative. Meanwhile, Christian parents don't want their kids attending schools that teach God doesn't exist.

But there are few alternatives—private schools are held under the same rules and regulations as public schools, and Christian schools are illegal. Some parents choose to homeschool their children or send them to other alternative schools, but they lack legitimacy and authorities could raid them at any time. Some are choosing to send their children to the United States. And with schools in the United States desperate for more money, an increasing number of Chinese students are applying for American high schools: In 2005 only 65 Chinese students attended U.S. private high schools, but last year the number was 6,725.

When Lei's parents heard about a program that sends Chinese students to attend a Christian high school in California, they jumped at the offer. They were impressed by the school's 100 percent college acceptance rate, with 50 percent of students going to University of California schools. The high school also includes daily Bible classes, weekly chapels, and an application of biblical worldview to all subjects, and the students live with Christian host families. Lei's parents, who are not Christians, didn't mind the Christian influence because they "figured Christian teachers and students would be kind," he said.

Now Lei enjoys working in the high school's science lab, tinkering in the robotics club, playing basketball—things he wouldn't have had the time to do in China—and pursuing a dream: "I am not afraid of China education. ... I have a lot of friends who come to America, Canada, or England, and some of them I know are avoiding it, some of them don't have a dream, but I do. I want to be a businessman."

Sarah, a school consultant in China, said she meets many students like Lei's friends who come to the United States to take the easy way out and will "bring problems from China to the United States. I see the movement growing in an alarming rate, and my biggest concern is quality control on both sides." For the high school in California, this means a three- to six-month screening process that includes meetings with the families, interviews with the students, and English assessment tests. Sarah tells prospective students what to expect at the school, and if students are still interested, they are asked to fill out the application, file for a U.S. visa, and take an English prep program.

Parents often pay education agents thousands of dollars to send their kids to schools overseas, and some agents help students lie on their transcripts to get into American schools. In one instance, an agent referred to Sarah a Chinese student who had spent some time in a juvenile reform school. When she asked the agent about the stint, he responded that the student was there for a weight-loss program, but she learned the student had actually been sent there because of his gang involvement.
