(CNN)Only a few students can say that they have been accepted into every Ivy League school in the United States: Harvard, Yale, Brown, Columbia, University of Pennsylvania, Dartmouth, Princeton and Cornell.
Among those who can call themselves members of this exclusive club are Augusta Uwamanzu-Nna and Kelly Hyles. They received acceptance letters last year from all eight of the Ivy League schools. Harold Ekeh did so the year before last.
Students like Martin, 17, and Kwasi, 20, are often celebrated for their successes. Yet the spotlight is seldom turned on their parents -- the adults who raised them.
Kwasi, who is from Shirley, New York, described a jovial childhood with high expectations. "More or less, I have African 'tiger parents,' " Kwasi said.
Martin, who lives in Fargo, North Dakota, described his parents as more hands off. "They let me be a free spirit," he said.
Here's a look at how two different parenting styles, in two different states, led to Martin and Kwasi being accepted into all eight schools.
'People think my opinion is crazy, but ... it can be done'
Kwasi's parents, Ebenezer Enin and Doreen Enin, immigrated to the United States from Ghana in their late 20s. They raised Kwasi and his sister, Adwoa, to always value education, he said. Adwoa is now 17, and awaiting her own college acceptance letters.
"Looking at their perspective, in Ghana, for example, only the richest people can go to college because they're the only ones who can pay for it, because loans don't exist. Everybody would want to go, if able. In America, there's always a way to make it happen, provided there's some financial support and stability," Kwasi said.
"My parents really, really don't like seeing smart, able-bodied people not perform to the best of their abilities," he said. "I think that is the overarching mentality that they've applied to me academically while growing up, and that's kind of the life motto I have."
Ebenezer said that he would not tolerate any grades on Kwasi's report cards lower than a 95%, and that was because he knew such grades -- even though they were good -- were not the best that his son could achieve.
"I would say a 95 to 100, that should be your goal, that should be your score in any class that you're taking. Stay very focused, and you can do it," said Ebenezer, who is a registered nurse. His wife, Doreen, is a nurse assistant.
"People think my opinion is crazy, but look, it can be done," Ebenezer said.
"You have all of the resources in this country to do extremely well," he said. "You have libraries. You have computers. You have teachers. You have online resources. There are so many things to help you. If only you are serious, you can do it. It doesn't matter your background."
Meanwhile, Martin in North Dakota said that his parents rarely checked his grades.
"My parents, they're the reasons I got into all of these colleges, but not in the way that a lot of people would assume," Martin said.
"They never really pushed me academically. They sort of just let me do what I wanted. They let me be a free spirit and from that I was able to motivate myself heavily to pursue the subjects I want," he said. "That's also important for college because within a college environment, there's no parent telling you what to do."
Kris Altenburg, Martin's mother, said that since Martin's interests were productive -- he enjoyed science and playing his violin -- her husband Kent and she gave him a lot of independence.
"I just think, if they're doing something positive, just kind of sit back and let kids do what they need to do," said Kris, who is a licensed practical nurse. Kent is a fund raiser for a PBS affiliate in Fargo and works for the Fargo stage union.
As for Martin, "He just really likes to learn," she said. "His dad and I, we never pushed him. In fact, through the course of high school, I told him to slow down and cut back on things, because I worry more about the health aspect if he stresses himself out and doesn't get enough sleep."
Kris said that she applies similar principles while raising Martin's two younger sisters, who are 11 and 13. "I just want them to be happy," she said.
A tale of two scholastic superstars
When Martin was a young boy, he would sit in his family's basement in Fargo, and read old math books. With his big blue eyes scanning the words on the page, he would dream of using mathematical equations to chase down tornadoes and other extreme weather events.
At that age, if you asked Martin what he wanted to be when he grew up, he would say without hesitation, a meteorologist.
"This year, I was president of my school's environment club and a lot of the projects we did this year focused on a shift in communication efforts," Martin said. "Environmental concerns aren't appreciated that much within my school and within my state, and I want to change that."
Some 1,500 miles away in Shirley, New York, Kwasi Enin also had aspirations to change his community -- and the medical field.
"Somewhere between kindergarten and second grade, I was asked the typical, 'What do you want to be when you grow up?' and I just said, 'A doctor,'" Kwasi recalled.
"It was first a little dream," he said. "Now it is trying to actually finish the path to get to medical school and practice someday."
As a child, Kwasi was quick to smile, had a big heart for those in need, and developed a love for music. He said that next year he will be singing with the Yale Whiffenpoofs, the world's oldest collegiate a cappella group.
In high school, Kwasi sang in his church's choir, played the viola and volunteered at a local hospital in his hometown, about an hour and a half outside of New York City.
Now, he continues to volunteer at medical centers in New Haven, Connecticut, and conducts independent biology research.
Last summer, "I was studying basically how stem cells work in planarians, which are little flatworms. These flatworms, if you cut them up down to one 300th of their size, they can completely regenerate," Kwasi said. "We want to see what key biological markers, what key proteins in these stem cells allow them to be so hyperactive."
He said that high school is when students should not only pinpoint what career fields they're interested in, but also pursue extracurricular activities in those fields.
"Spend a summer in high school to shadow a doctor and see what that's like. Or, work in a law firm or even find a music producer in the area and see if you can work with them if that's what you're interested in," Kwasi said. "Try to get exposed to different career paths because often the best chances of doing well starts before college."
For himself, Martin, and others, Kwasi said that he thinks straight As and high standardized test scores were not the only factors that helped them get accepted into all eight Ivy League schools. They also volunteered; and not just participated in, but held leadership positions in extracurricular activities, he said.
"These schools are really interested in people who help their community and I think all of those factors, put together, influence why we fit well into the mold of each of these schools," said Kwasi, who also works as a college admissions consultant for the SAT and ACT test preparation company Prep Expert.
Martin and Kwasi aren't the only ones who have something in common. Their parents have some commonalities, too. Three to be exact.
'I had an inkling'
First, when Kwasi realized he was accepted into all of the Ivy League schools, his father Ebenezer asked, "What's the financial aid look like?"
Similarly, when Martin's family realized that he had been accepted into all of the Ivy Leagues, his parents asked how much of a dent the schools would leave in their wallets.
"A lot of times my first question is, 'How much does it cost?'" said Martin's mother, Kris.
Both families, who describe themselves as being of middle class, said that they have been awarded financial aid and scholarship packages, which make some Ivy League schools more affordable than a state college.
Second, both pairs of parents want the world to know that their sons are not nerds.
"This year I made the homecoming court, so I'm fairly well-liked by other students," Martin said. "My mom actually said that I need to mention that I made homecoming court so people don't think I'm a big nerd."
Kwasi's father had the same sentiment.
"He wasn't like a nerd, always studying. He had fun, too," Ebenezer said about his son. "He had friends who would come around, and they would go to the beach and have fun. So he had a complete life."
Third, both parents were not surprised to see the wave of Ivy League school acceptance letters bearing their child's name.
"I had an inkling that something like that could be possible," said Kris Altenburg.
Kwasi's family felt the same way, he said, adding that they expected him to excel academically.
How academic success can be a family affair
It turns out that parents and their parenting practices can influence children's academic success, said Nancy Hill, a developmental psychologist and professor at the Harvard Graduate School of Education.
" 'Hands-off' parenting can work quite well when students are doing well and have strong positive relationships with teachers and other adults at school. For students who are not well connected and well supported by adults at school, 'hands-off' parenting can leave youth feeling marginalized and disconnected from their schoolwork," Hill said.
"Strict parenting can be beneficial for youth in contexts where there are challenges to success. For example, many students of color experience discrimination, negative teacher bias and are subject to negative stereotypes," she said. "In these contexts, strict parenting can be beneficial and has been shown to be positively related to achievement, especially grades, test scores and behavioral engagement."
The report involved a survey of about 540,000 students, around 15 years old, across 72 questions.
Among the students who completed the survey, those whose parents reported "spending time just talking to my child" were two-thirds of a school year ahead of their peers in science learning; and even after accounting for socio-economic status, the advantage remained at one-third of a school year.
For all parents, Hill said that focusing on developing your child's love for learning and helping them find their passion and purpose can be beneficial.
"In our research with adolescents, we find that parenting practices that include helping youth link their education to future goals, looking for ways to increase students opportunities for autonomy, are positively related to achievement, in part because it helps students see the value and meaning of schoolwork," Hill said.
"That is far more important than focusing on acceptance into the Ivy League school. I don't say this to belittle the accomplishments of these two very talented and fortunate students. But, because without meaning and purpose, it will be far less fulfilling," she said. "With meaning and a sense of purpose, students can find success and contentment at many schools."

Kwasi and Martin seem to agree.
"Try to find colleges that match your interest," Kwasi said when asked about advice he has for high school students. "Schools like Ivy Leagues have different strengths and weaknesses in different fields, and knowing what their strengths and weaknesses are can help you."
Martin said that students should apply to their dream schools, even if they fear they won't get accepted.
"Still apply," he said. "If you're able to get into these colleges, you're probably going to be able to succeed in this environment and you're going to succeed in whatever college environment you put yourself into, whether it's community college or state college or Ivy League college."
