Millions of workers are choosing vocational training over university degrees to avoid massive debt

Many people are opting for vocational training instead of traditional four-year degrees since there are rewarding careers at lower educational costs. The current top trade opportunities include electricians, diesel mechanics, HVAC technicians, and renewable energy technicians.

According to the Organisation for Economic Co-operation and Development (OECD), in 2024, 43% of students in high school were enrolled in a vocational education and training (VET) program. It's clear that there's been a shift in educational attitudes; students typically chose traditional university programs in the past, but that's no longer the case.

In today's world, students are opting for vocational training instead, and for good reason.

What Is the Definition of Vocational Training?

Vocational training is a type of non-traditional education that prepares students for a specific occupation by teaching the practical skills and technical knowledge needed to perform that job. In traditional classrooms, there's an emphasis on theoretical learning, but in vocational schools, they focus on hands-on experience and industry-specific techniques.

You can receive vocational training at:

• Trade schools
• Community colleges
• Technical institutes
• Employer-sponsored apprenticeships

The length of vocational school programs is different as well, with some lasting several weeks while others last multiple years.

One of the biggest trade school benefits is that students don't incur large debt when going through education. This is why many people are flocking to trade schools instead of universities.

What Are the Current Top Trade Opportunities?

There's an increase in skilled labor demand across the country, which makes vocational training even more worth it. But what are the top opportunities out there?

These are the main trade careers you should consider.

Electricians

Electricians will always have a place in the world, especially as we expand our electrical infrastructure and modernize aging buildings. There are also more energy-intensive facilities being built, which need electricians on the job, too.

Specializations in this industry include:

• Residential installations
• Commercial construction
• Industrial maintenance
• Advanced electrical systems

What's great is that you can start with an apprenticeship that usually combines on-the-job experience with classroom instruction. You'd then get your state license afterward; each state's requirements vary, so do your research before starting out.

Being an electrician can be highly rewarding if you enjoy practical problem-solving and working with electrical systems.

Diesel Mechanics

The diesel mechanic route can be interesting for those who are interested in engines, diagnostics, and heavy equipment, as in this role, they'll inspect, maintain, and repair not only diesel-powered vehicles but also machinery.

This role is now evolving, too, as technology becomes more advanced. This means that in addition to technical skills, diesel mechanics must also develop skills in things like electronic control systems and computerized diagnostics.

Employers can include:

• Trucking companies
• Equipment dealerships
• Repair shops
• Public transit agencies
• Construction businesses

People can look at top-earning diesel mechanic roles if they get industry certifications. Even with basic certification or an associate degree, the heavy equipment technician income is very decent.

HVAC Technicians

HVAC technicians are also in high demand because most houses have air conditioning and/or heating. These systems need regular inspections, maintenance, and repairs to keep running smoothly, and expert knowledge will always be needed. Not only do existing HVAC systems need servicing, but so do those in new builds.

Potential specializations here include:

• Commercial refrigeration
• Building automation
• Industrial climate control

In general, training will involve a technical program or apprenticeship. Once you've received your certifications, you can then work in various areas, such as emergency calls or outdoor installations. With enough experience, you can even advance into service management or business ownership.

Renewable Energy Technicians

According to S&P Global, the US is projected to add over 90 GW of new capacity in 2026 (51.2 GW of solar, 25.7 GW of energy storage, and 13.1 GW of wind). There's more and more focus on renewable energy, which means there's a growing demand for renewable energy technicians.

How you enter the industry will depend on what career you're interested in. For example, solar installers may take technical courses, while wind turbine technicians complete a specialized postsecondary program.

You may be well-suited as a renewable energy technician if you enjoy mechanical systems and electrical troubleshooting, and you like to travel and aren't afraid of heights.

Frequently Asked Questions 

What Is the Long-Term Value of a College Degree?

The long-term value of a college degree is that you have higher earning potential and access to specialized careers. In addition, you'll have more opportunities for professional advancement.

Not only can you access good employment, but you can also benefit from:

• Professional networks
• Transferable analytical skills
• Eligibility for management positions

Not every degree is worth the same, though, as you'll have to account for:

• Field of study
• Tuition costs
• Student debt
• Availability of relevant jobs

What Trade Is Quickest To Learn?

One of the quickest trades to learn is commercial cleaning. Many entry-level positions require only a short period of practical instruction (days or weeks).

Do note that some specializations require additional training or certifications, such as:

• Industrial cleaning
• Hazardous material cleanup
• Healthcare facility sanitation

If you want to start your own cleaning business, then you'll also need to learn about topics such as customer service and pricing.

In general, there's a low barrier to entry in this industry, but your earnings may vary based on your location and specialization, as well as your employer and working hours.

What Is the Least Valuable Degree?

There's no universal "least valuable degree" because it depends on what your goals and financial circumstances are.

With that said, a bachelor's degree in general studies may have a weaker return on investment since it focuses on broad education. If you want better opportunities, then it may be better to pursue certifications, internships, or work experience to stand out.

The most important thing to do before committing to a degree is to check not only the total educational costs, but also employment outcomes.

Give Vocational Training a Try

If you've been wanting a career change but don't want to go back to university to make it happen, then give vocational training a try. Not only are these educational paths shorter, but they're usually more affordable, too.
