Majors, Careers and Earnings
How a declared major connects to career paths, earnings variation, licensing rules, and the cost of changing course — before and after enrollment.
A major shapes which careers are open to you, what additional credentials you may need, and how much your earnings could vary. Knowing those connections before you commit helps you match the cost of a program to what the field realistically supports.
Picking a major is often treated as a statement of identity rather than a decision with financial and logistical consequences. This section treats it as both. The pages here walk through how to research a field before committing, what earnings data exists and what it actually measures, and where a given major leads — including whether it requires graduate school, a license, or an internship to be employable at all.
The pages are grouped to follow a realistic decision sequence. You start by understanding what a major is and how to research one, move into evaluating fields by outcomes and requirements, and then look at the complications — changing your mind, doubling up, and matching your borrowing to what a field can support. Career services and employer skills expectations appear toward the end because they are most useful once you have narrowed your options.
Nothing here tells you which major to choose. These pages give you the questions to ask and show you where the answers are published, so the decision is based on real information rather than assumptions about what a degree title leads to.
This section covers major selection, career pathways, and earnings in the context of choosing a college program. It does not cover how schools compare on graduate outcomes at an institutional level — that is handled in Comparing Schools With Outcomes Data — and it does not cover admissions, applications, or transfer decisions.
What you need to understand first
Field of study vs. occupation
A major and a career are not the same thing. Many occupations draw graduates from several different majors, and many majors lead to more than one occupational path. Understanding this gap is why researching a field means looking at what graduates actually do, not just at the major's name or department description.
Earnings range within a field
Published earnings figures for a major are usually medians, which means half of graduates earn above and half earn below. The spread between low and high earners inside a single field can be wide, driven by industry, geography, employer size, and role. A median alone does not tell you where in that range you are likely to land.
Licensure and credential requirements
Some fields require a state-issued license or certification before a graduate can work legally in the occupation. The requirements — exams, supervised hours, background checks — vary by state and are set by state licensing boards, not by the college. Choosing one of these fields means the major alone is not sufficient to enter the career.
Graduate school as a requirement
In certain fields, an undergraduate major functions as a prerequisite for a graduate or professional degree that is the actual entry credential. The undergraduate program is not the end of the education path; it is the beginning of a longer and more expensive one. Knowing this before enrollment changes the borrowing calculation significantly.
Cost of changing course
Switching majors can add time to a degree, require repeated courses, or disqualify credits already earned. How much it costs depends on when the change happens, how different the new major's requirements are, and whether financial aid covers the additional time. This is not a reason to avoid changing — it is a reason to understand the mechanics before deciding.
Matching borrowing to a field
The amount a student borrows to complete a degree has to be repaid out of income from work. Different fields support different debt loads based on typical starting salaries and salary trajectories. Borrowing figures that are manageable in one field may be difficult to sustain in another, which is why field of study is part of the borrowing decision.
Mistakes to avoid with Majors, Careers and Earnings
Using a major's name as a proxy for career certainty
Why it happens: Major titles sound specific, so students assume they map directly to a single occupation, when in practice most majors feed multiple paths and some common careers hire from many different majors.
What to do instead: Look at the occupational data attached to a major — the Bureau of Labor Statistics Occupational Outlook Handbook lists typical educational backgrounds for specific roles, which shows you the real relationship between a major and a job.
Treating the median salary figure as a personal prediction
Why it happens: Salary data for majors is widely published and easy to find, so it is easy to assume the number applies to you, when it is an aggregate that flattens variation by industry, location, and role.
What to do instead: Look for earnings data broken down by industry and region within a field, not just the overall figure, and note the range from the bottom quartile to the top — that spread is where the real information lives.
Waiting until sophomore year to check graduate school or licensure requirements
Why it happens: Students often assume they have time to figure out post-graduation requirements later, not realizing that some fields require specific undergraduate coursework that must start in the first or second year.
What to do instead: Research the entry requirements for your intended occupation before you enroll, then map those requirements backward to the courses you need to have completed by graduation.
Majors, Careers and Earnings: common questions
Does my major determine my career?
Not in most fields. Many careers hire graduates from several different majors, and many majors lead to more than one type of work. The exceptions are fields with licensure or graduate school requirements, where the academic path is more prescribed. For most students, the major is one factor among several — alongside skills, experience, and credentials — that shapes which opportunities are open.
Where can I find reliable earnings data for a major?
The federal government publishes earnings data through the College Scorecard, which reports earnings by field of study at specific institutions, and through the Bureau of Labor Statistics, which reports earnings by occupation. These are the primary published sources. Neither predicts an individual outcome — they report what past graduates earned, and the figures depend on when the data was collected and how the sample was defined.
Is it bad to be undeclared?
It depends on the field and the timing. Being undeclared in the first year is common and, in many programs, has no lasting cost. Being undeclared past the point when required courses need to begin can delay graduation or require summer coursework to catch up. The page on undeclared students in this section explains which situations are low-risk and which carry real scheduling consequences.
Can I change my major after I start?
Yes, and many students do. Whether it adds time or cost depends on how different the new major's requirements are from the old one, how many credits transfer toward the new program, and when the change happens. A switch in the first year typically costs less than one in the third year. The page on changing majors in this section covers the specific mechanics.
What does it mean when a field requires licensure?
It means a state-issued license or certification is legally required to work in that occupation, and that the license is separate from the college degree. Licensing requirements — including exams, supervised hours, and state-specific rules — are set by state licensing boards. Completing the degree without meeting the licensing requirements means you cannot legally practice in that field in that state.
Do employers care what I majored in?
It varies by employer and role. Some positions require or strongly prefer a specific major; others hire across disciplines and weight skills and experience more heavily than the major itself. The pages in this section on skills employers ask for across majors and career services cover what employers typically look for and how field-specific versus transferable skills factor into hiring decisions.
