Why a High School Diploma Still Matters
The numbers tell a clear story. The U.S. Bureau of Labor Statistics reports that workers with a high school diploma earned a median of about $946 per week, compared to significantly less for those without one. Over a year, that gap can exceed $13,000, and over a working lifetime, the difference reaches well into six figures.
Beyond the paycheck, a diploma unlocks options that a GED alone often cannot. Federal financial aid, military enlistment, trade apprenticeships, and many employer tuition-reimbursement programs routinely require a diploma from an accredited high school. Community colleges welcome diploma holders without placement-test hurdles, and some merit-based scholarships simply are not available to equivalency credential holders. According to a National Center for Education Statistics study, roughly 30 percent of high school diploma holders eventually earn a bachelor's degree, while only about 5 percent of GED recipients do.
That said, the GED and HiSET remain legitimate alternatives. For someone who left school many years ago and wants a faster route, passing a four-subject equivalency test can take as little as a few months of prep. But the choice depends on your goals: if college, skilled trades, or the military are on your horizon, a traditional diploma tends to open more doors.
Your Options for Earning a Diploma as an Adult
1. Adult High School Programs at Community Colleges
Many community colleges across the country offer Adult High School (AHS) programs that are often free or low-cost. Cape Fear Community College in North Carolina, for example, launched an AHS program that charges no tuition and issues a diploma recognized by employers and universities alike. South Piedmont Community College offers similar free classes and even provides a voucher for continuing education upon graduation.
These programs are credit-based, meaning if you have prior high school credits, you can pick up where you left off. Classes are offered in person and online, with evening and weekend schedules designed around working adults.
2. Accredited Online High Schools
If your schedule is unpredictable, regionally accredited online schools offer self-paced courses that you can start any time. BYU Online High School runs a Flex On Demand track for adults 18 and older at about $275 per course, with 200-plus courses and teacher office hours. Northgate Academy charges roughly $99 per month with no long-term commitment, so a motivated student who finishes in five months pays only about $495.
The key word is accreditation. A diploma from a regionally accredited school is accepted by colleges, employers, and the military. Before enrolling, verify the school's accreditation through the U.S. Department of Education database or your state's education agency.
3. Library-Based Programs
Public libraries in cities like San José partner with Career Online High School to offer adults 19 and older a chance to earn a diploma plus a career certificate in fields like child care or office management. These programs pair each student with an academic coach and require roughly ten hours of coursework per week. Scholarship availability varies by city, so check with your local library system.
4. High School Equivalency (GED or HiSET)
For adults who prefer testing over coursework, the GED costs about $144 for the full battery in most states, with per-subtest retake fees varying. Many states offer free preparation classes through adult education programs, and the test itself is available in person or online with proctoring. The HiSET offers a paper-based alternative for those who struggle with computer-based testing.
Comparison Table
| Program Type | Example | Typical Cost | Best For | Strengths | Drawbacks |
|---|
| Community College AHS | Cape Fear CC, South Piedmont CC | Often free | Adults with prior credits | In-person support, recognized diploma, no cost | Fixed schedules, limited locations |
| Online High School | BYU Online HS, Northgate Academy | $275/course or ~$99/month | Busy adults needing flexibility | Self-paced, start anytime, accredited | Requires self-discipline, costs add up |
| Library COHS | San José Public Library | Scholarship-based | Adults wanting career training | Diploma + career certificate, coaching | Age/residency requirements, waitlists |
| GED/HiSET | State test centers | ~$144 for GED | Fast test-based route | Quick completion, widely accepted | Some employers/colleges prefer diplomas |
A Real-Life Example
Maria, a 34-year-old warehouse worker in San Antonio, dropped out of high school in her junior year to help support her siblings. For over a decade, every promotion application included the same question: "High school diploma? Yes or No." She always checked "No."
In early 2025, she enrolled in her county's adult education program, which offered free evening classes and covered her GED test fee. She passed all four subjects in five months. The immediate result was a shift supervisor position with a raise of about $4,000 per year. But the bigger change came later: she used her credential to qualify for a community college certificate in logistics, and her employer's tuition program covered most of the cost.
Maria's story illustrates a pattern that adult educators see constantly: the credential itself is the key that turns the lock, and everything else follows.
How to Choose the Right Path
Start by asking yourself three questions.
First, how many credits do you already have? If you completed two or more years of high school, an AHS program lets you finish exactly what is missing. If you barely attended or left long ago, an equivalency test or a self-paced online diploma may serve you better.
Second, what is your timeline? Need something within a year? The GED or HiSET is typically the fastest route. Comfortable taking 18 to 24 months? An online diploma program offers a steadier, more structured experience.
Third, where do you want to go next? If your goal is a four-year university, prioritize a regionally accredited diploma. If you just need to satisfy an employer's baseline requirement, either path works.
Action Steps
- Contact your state's adult education office or your local community college and ask about Adult High School and equivalency prep programs. Many are free and funded by state and federal grants.
- Request your old transcript. Even if you think it is lost, your last school district keeps records, and transferring prior credits can cut months off your completion time.
- Verify accreditation. Use the U.S. Department of Education's database to confirm any online school you consider.
- Check your local library for Career Online High School or similar partnerships.
- Set a study schedule. Whether you choose coursework or a test, consistency matters more than speed. Ten hours per week is the sweet spot for most adult learners.
The Bottom Line
A high school diploma is one of the few credentials that pays for itself almost immediately, in both earnings and opportunity. The barriers that kept you from finishing school years ago do not have to define your future. Between community college programs that cost nothing, online schools that fit around a 40-hour workweek, and library initiatives that add career training on top of a diploma, there is a path that fits your life. The first step is simply picking up the phone or opening an application form. Thousands of adults do it every year, and the only thing they had that you do not is the decision to start.
