Of the nearly 10,000 students enrolled at Brookdale Community College in central New Jersey, about 17 percent are still in high school.

Some of them travel to the campus during the school day to take courses in introductory English, history, psychology and sociology. Others stay right at their own secondary schools and learn from high school teachers who deliver college-course lessons.

They’re part of a practice, increasingly popular nationwide, that sees teenagers complete advanced classes — mostly offered through community colleges — while juggling typical high school activities like sports practices, part-time jobs and dances.

“One of the reasons why we put a lot of time and effort into the high school programs, to get students started on the college pathway in high school, is it’s going to save them a lot of money, save them a lot of time and hopefully get them to their career goals sooner,” says Sarah McElroy, dean of pathways and partnerships at Brookdale Community College.

Called dual enrollment, the phenomenon grew for the third year in a row this year. And the growth is steep — up 10 percent compared to last year, according to the National Student Clearinghouse Research Center. That’s significant in an era when college leaders are concerned about attracting and retaining students who may be skeptical about the value of a degree and also worried about the impending “enrollment cliff” resulting from fewer Americans of traditional college age coming up in the next few years.

Nationally, about a fifth of students who take community college courses these days are still in high school, according to John Fink, a senior research associate and program lead at the Community College Research Center. In some parts of the country, the share is even higher — it’s almost 40 percent in Iowa and Indiana, for example.

Among people who started ninth grade in 2009, about a third took some type of dual enrollment course, Fink says, adding, “That’s a big penetration into the high school market.”

The trend is catching on with policymakers and educators as they look for ways to spur college-going while also ameliorating high tuition prices.

“People are concerned about the costs of higher education: state legislators and governors, families and students,” says Josh Wyner, founder and executive director of the College Excellence Program at the Aspen Institute. “The idea of getting college credit while you’re in high school is appealing as a way of holding the cost of college down.”

Brookdale Community College is in a state that has named dual enrollment as a priority. By 2028, New Jersey aims to double the number of high school students enrolled in at least one dual enrollment course, ensure all high schools provide dual enrollment options, and close access gaps to these programs for different groups of students.

That push is evident at Brookdale. From 2018 to 2023, the college recorded a 39 percent increase in Monmouth County high school students enrolling in its college-level courses. The institution hopes to increase enrollment among high school students by 50 percent more by 2028.

“We are trying to reach every high schooler in some way,” McElroy says.

Yet Brookdale, other community colleges, and their K-12 school partners face a few challenges in order for dual enrollment to “live up to its potential as a lever of access and equity to college and careers,” Fink says.

Good for Everyone?

Dual enrollment takes many forms and goes by many names. Some programs are run through well-organized early-college high schools that help students earn a full associate degree by the time they graduate. Others are more free-form, allowing students to take one or two courses as they please — a style some observers have critiqued as “random acts of dual enrollment.” Brookdale offers several different models through its high school partnerships.

Across these varied formats, dual enrollment seems to have become popular because it’s beneficial for all parties involved, according to education experts.

It’s good for students, Fink says, citing two decades of research that shows it leads to better high school and college completion rates. It’s good for community colleges, which advance their missions to serve their surrounding area — and also possibly create “a larger pool of students coming back to you” for additional classes after high school, too, he adds.

In fact, dual enrollment is “the most consistent source of enrollment growth for community colleges over the past decade,” says Nick Mathern, director of K-12 partnerships for Achieving the Dream, a nonprofit that supports a network of community colleges. “Depending on how you break down the age cohort, there is a way in which you see it’s the only source of enrollment growth for community colleges over the last decade.”

Especially in states that provide extra public funds to support dual enrollment, it’s good for school districts and public schools, proponents argue, since they can use those programs as a selling point for attracting families and students who might otherwise look to private schools, or public schools elsewhere.

These dual-enrollment programs are not replacing Advanced Placement courses, which have been a mainstay at high schools for decades and remain popular, Wyner says. Among the three-quarters of high schools that offer advanced coursework, about 78 percent offer dual enrollment compared to 76 percent that offer AP classes. But one advantage dual enrollment may have over the AP program is that it offers a much wider catalog of options, including some career and technical courses, which may appeal to a broader set of students.

“For a lot of students who are not eager to take more purely academic courses — or about test-taking and writing papers — this is an enormous opportunity to get excited about higher education through fields of study not offered in high schools,” Wyner says.

Some of the high schools that feed into Brookdale offer dual enrollment, AP courses and the advanced International Baccalaureate curriculum all at once, McElroy says: “We are finding students are taking a menu of options.”

One bonus she sees regarding the dual enrollment courses: Students know they’ll earn college credit for taking them, whereas they’ll only get college credit for AP classes if they score high enough on standardized exams.

“It transfers so widely. Four-year colleges are taking those credits,” McElroy says. “That’s helped to elevate dual enrollment across the state.”

Addressing Inequality

Yet data on dual enrollment reveals that not all student groups participate at the same rate.

Racial minorities, men and students who would be the first in their families to go to college are underrepresented in these programs. In the county that feeds into Brookdale Community College, for example, “our Black and Hispanic students are not finishing at the same rate white students are,” McElroy says.

There are a few factors that contribute to this inequality, Fink says. For instance, some schools use standardized test scores to determine which students are eligible to participate, creating barriers since some groups of students consistently score lower than others. Many dual enrollment courses are taught by high school teachers who have the credentials needed to instruct at the community college level — typically a master’s degree in a relevant discipline — and at some high schools, there is a shortage of qualified teachers. And while some states have arrangements that make dual enrollment courses free for students, in other regions, families have to pay.

“If you have to pay extra to take college courses in high school, you’re going to get wealthier, whiter families taking advantage,” Fink says.

Then there is an older mindset to contend with, one that views dual enrollment primarily as an option for academically advanced students who are looking for enrichment.

It is true that some students choose dual enrollment through Brookdale to improve their chances of being accepted into a selective four-year university, McElroy says.

“We know from the research that dual enrollment courses are more rigorous than the standard- issue high school course,” Wyner says. “And so for a lot of parents and students who are eager to be challenged, they see dual enrollment as an opportunity to get exposure to college-level work and get challenged in their coursework.”

But some educators and researchers hope dual enrollment can serve as an opportunity to broaden access to higher education for “students on the margins of going to college,” Fink says, by boosting their confidence, by introducing them to topics they won’t learn about in high school that might inspire them to consider going to college, and by creating momentum for possible postsecondary studies.

“I don’t begrudge middle-class students and college-bound students the opportunity to take classes in high school,” Mathern says. “But if we are not intentional about how we deploy these programs, we are not actually changing how many students in any given community earn a college credential.”

To that end, Brookdale offers college readiness courses to its high school students who participate in dual enrollment programs, designed to teach them skills they need to succeed in advanced classes.

“It shows students they can do it,” McElroy says. “College could be for them.”

For more high school students to succeed in dual enrollment, experts stress that schools and colleges have to specifically look out for them and guide them through the process.

“We think colleges should be establishing a shared vision with their local school districts about what they want to achieve for dual enrollment,” Mathern says. “As we open the door wider, we can’t just give more students access to college classes and call it good.”

After all, if a student tries a dual enrollment class and doesn’t succeed in it, the experience can leave them worse off than if they hadn’t attempted it all, either by wasting their tuition dollars, leaving them with a low grade that will follow them on a transcript or by discouraging them from pursuing more higher education.

“It’s unethical to really not provide the supports and advising,” Fink says. “Unless you’re doing all of those things, it can be harmful and have the opposite of the intended effect.”

To that end, Brookdale has a dedicated team of support staff for its dual enrollment programs, McElroy says, explaining, “We want to serve the students as much as possible.”

Despite the flaws that remain in many dual enrollment programs, Fink is optimistic that, with fine-tuning, they can serve as a promising pathway to better college and career-training options for more young people.

“There are a lot of reasons we would want to do things differently in the college-to-career transition. It’s largely producing poor and inequitable outcomes,” he says. “What do we do with senior year of high school? Students are checked out. By bringing more career and postsecondary training into high school, you’re blurring the line, and that’s a positive thing for students.”
