Choosing a college major can feel overwhelming—especially if you’re unsure about your future. But picking a major isn’t about locking yourself into one job forever. It’s about creating a smart plan that can guide your college journey, help you graduate on time, and even save your family money.
Too often, students skip career assessments that could help them discover new options and avoid costly detours. These simple tools can match your interests and strengths with real careers and majors you may not have considered.
In this post, we’ll cover why picking a major matters, how to explore your options, and two free tools that can help you make a more confident choice.
Why Does Picking a Major Matter?
Your college major is the main subject you'll study while in school. It shapes the classes you'll take, the clubs you might join, and the kinds of internships and job opportunities you'll hear about. Picking a major can help you focus your time and energy—and sometimes even your money.
Some careers pay more than others, and your major can affect your future salary. For example, majors like nursing, computer science, or engineering are often tied to high-paying jobs and strong career demand. Other majors, like history or music, may open up different career paths and might require extra schooling if you want to specialize.
It's also important to know that some colleges limit how many students can choose certain majors. These are called "impacted" or "competitive" majors. If you're applying to a program like nursing, business, or computer science, you may need to choose that major when you apply to the college. If you wait too long, it may be harder—or even impossible—to switch into it later.

Most Students Change Their Majors—And That’s Okay
It's completely normal to change your mind. In fact, more than half of all college students change their major at least once. Some students enter college thinking they want to be doctors, only to realize they love teaching or business instead. Others might start off in a major they enjoy but find a new passion in a class they didn't expect to like.
So if you're feeling unsure, you're not alone. College is a time to explore, grow, and learn about yourself. It's better to try something and realize it's not for you than to never try at all.
When Do You Have to Decide?
Every college is different, but most students choose their major by the end of their second year. That gives you time to explore other classes and figure out what feels like a good fit. But if you want to apply for a limited-space major, like engineering or nursing, you may need to decide sooner—sometimes even before applying to college.
That's why it's a good idea to start thinking about your strengths and interests now, even if you're not ready to commit to a major yet.
How to Explore Majors and Careers
Start by thinking about what you enjoy doing and what subjects interest you most. Do you like solving problems? Working with your hands? Helping people? Creating things? These clues can help point you toward a field that fits your personality.
One of the best ways to explore careers is by using a free online tool like CareerOneStop, which is sponsored by the U.S. Department of Labor. On this website, you can do a self assessment which help you discover what you're good at and what you enjoy by asking questions about your interests and strengths. When you choose a career that matches these things, you're more likely to enjoy your work and do well in it.
You can also explore careers based on your interests on CareerOneStop, watch videos about different jobs, and learn how much each career pays. It also tells you what type of education or training is needed, whether the field is growing, and even links to job opportunities in your local area. It's a great way to learn what different careers actually look like in the real world.
Your high school might also offer access to a program like Naviance, which has tools to help you learn more about your interests and personality. The Career Interest Profiler asks you questions about what you like and suggests possible careers or majors to explore. Another feature, called Do What You Are, matches your personality type to careers that might be a good fit. Ask your school counselor if you have access to this program.

Don’t Forget About Internships and Real-Life Experience
You don't have to wait until after college to try out a career. Internships, job shadowing, part-time jobs, or even volunteering can give you a real look at what a job is like. Programs like Urban Alliance internships in Detroit or the Dallas Mayor's Interns program are available to high school students. This kind of experience can help you decide whether a career feels right—or helps you rule something out.
Internships are also a great way to build your resume, make professional connections, and sometimes even land a job offer after college. Many students get their first job through someone they met during an internship. So, don't underestimate how valuable real-world experience can be.
Worried About Choosing the “Wrong” Career?
Many students worry that the major they choose will decide their entire future—but that's just not true. Most adults change jobs several times in their life, and many end up working in fields that are different from what they studied in college. Some people go back to school later, start their own business, or build a career based on something they learned through a hobby or side job.
Your first career is just that—your first. It's a starting point, not a forever decision. That's why the best thing you can do right now is learn about yourself and the options available to you. The more you explore now, the more confident you'll feel when it's time to choose.
Choosing a Major with the Future in Mind
As you think about your major, it’s also smart to look at how the world is changing. Fields like artificial intelligence, cybersecurity, data science, and environmental tech are growing fast—and they’re shaping the future of work.
Even if you’re not into coding, there are roles in these areas that need strong writers, problem-solvers, and creative thinkers. So, while it’s important to follow your interests, keep an eye on emerging industries and the skills employers will be looking for in the next few years. Choosing a major with the future in mind can open more doors after graduation.
How Choosing a Major Can Save You Time and Money
Choosing a major early on—especially one that fits your interests and career goals—can actually help you save thousands of dollars in college. Here's why: every extra semester you stay in school costs money. Whether you're paying out of pocket or taking on student loans, time is money when it comes to college.
When students change majors multiple times or take too long to decide, they often end up with extra classes that don't count toward their new degree. That means more tuition, more books, and sometimes even an extra year or two before graduation.
But when students explore majors and careers early—by taking career assessments, using tools like CareerOneStop, or talking with a coach or counselor—they're more likely to find a good fit the first time around. That leads to better planning, fewer unnecessary credits, and more chances to graduate on time.
In short, choosing a major with intention doesn't just help with direction—it can help your family pay less for college.
Final Thoughts
Picking a major is important, but you don't need to have everything figured out right away. What matters most is being curious, staying open to new experiences, and using the resources around you to learn more about yourself.
Start with simple steps: take a career quiz, browse CareerOneStop, or talk to someone who works in a field that interests you. Ask questions. Try new things. And remember—it's okay to change your mind. Your college journey is about discovering what you want to do and who you want to become.
