High School Courses Career Guide

What Electricians Do

Electricians install, maintain, and repair electrical power systems, communications, lighting, and control systems in homes, businesses, and factories. As a residential electrician, you'll wire new homes, upgrade electrical panels, install outlets and fixtures, troubleshoot circuits, and make sure everything meets the National Electrical Code.

This isn't just pulling wire — you're solving spatial puzzles, reading blueprints, calculating loads, and making sure families are safe in their homes. Electricians are licensed professionals whose work is critical to every building that exists.

A Day in the Life

A typical day might start at 7 AM at a new-construction site where you're roughing in wiring for a home — running Romex through studs, placing outlet boxes, and pulling wire to the panel. After lunch, you might head to a service call at an existing home where a homeowner's breaker keeps tripping. You use a multimeter to diagnose the issue, find an overloaded circuit, and install a dedicated line for their new home office. You're usually done by 3:30 or 4:00 PM.

Some days are all about new construction; others are troubleshooting and repairs. The work is physical — you'll climb ladders, crawl in attics, and work in tight spaces — but it's mentally engaging too. Every job site is a different puzzle.

Why Electricians Are In Demand

Nearly every building needs electricity, and the demand is accelerating. The push toward solar energy, EV charging stations, data centers, and smart-home technology means electricians are more needed than ever. About 81,000 job openings are projected each year through 2034, and more electricians retire annually than new ones enter the field. This is one of the most in-demand trades in the country.

Work Environment

You'll work both indoors and outdoors — in homes, commercial buildings, and sometimes at height. Residential work tends to be more predictable hours (weekdays, daytime) compared to commercial or industrial. Most electricians work full time, and self-employed electricians often set their own schedules. Safety is paramount: you'll work with live circuits and must always follow proper lockout/tagout procedures.

What Plumbers Do

Plumbers install and repair the piping systems that carry water, gas, and waste in and out of homes and buildings. As a residential plumber, you'll install water heaters, run supply and drain lines, set fixtures (sinks, toilets, showers), repair leaks, and clear stoppages. You're the reason clean water flows and waste disappears — it's foundational infrastructure work.

A Day in the Life

Your morning might start at a new-construction site where you're roughing in drain lines and water supply for a home — measuring, cutting, and soldering copper pipe or cementing PVC, making sure everything slopes correctly for drainage. After a lunch break, you might respond to a service call: a homeowner with a leaking water heater. You assess the situation, shut off the supply, drain the old unit, and install a replacement. Between jobs you're loading materials, documenting work, and communicating with homeowners or general contractors.

Plumbing is physical — you'll work in crawl spaces, under sinks, and sometimes dig trenches — but it's also highly technical. Understanding water pressure, grade calculations, and building codes takes real expertise.

Why Plumbers Are In Demand

Every building with running water needs plumbing, and aging infrastructure across the U.S. is driving huge demand for repair and replacement work. About 44,000 openings per year are projected through 2034. Plumbing can't be outsourced or automated — someone has to physically be there, and that means strong job security for decades to come.

Work Environment

Plumbers work in homes, commercial buildings, and sometimes outdoors. The work involves lifting, crouching, and working in confined spaces. Many plumbers are on call for emergencies (burst pipes, sewer backups), and self-employed plumbers can earn premium rates for urgent work. Weather is a factor when working on exterior piping or new construction sites.

What HVAC Technicians Do

HVAC (Heating, Ventilation, and Air Conditioning) technicians install, maintain, and repair the systems that keep buildings comfortable year-round. That includes furnaces, air conditioners, heat pumps, ductwork, thermostats, and refrigeration units. You'll work with electricity, refrigerant, gas lines, and sophisticated computerized controls.

Modern HVAC is increasingly high-tech — today's systems include smart thermostats, variable-speed compressors, and IoT-connected monitoring. Technicians who understand both the mechanical and digital sides of the trade are especially valuable.

A Day in the Life

In summer, your day might involve installing a new central AC system in a home — setting the outdoor condenser unit, running refrigerant lines, mounting the evaporator coil, connecting electrical, and charging the system. In winter, you might troubleshoot a furnace that won't ignite — checking the ignitor, flame sensor, gas valve, and control board with diagnostic tools. In between, there's routine maintenance: cleaning coils, changing filters, checking refrigerant levels.

HVAC work is highly seasonal — summers and winters are busy with AC and heating emergencies, while spring and fall are maintenance season. You'll use multimeters, manifold gauge sets, leak detectors, and combustion analyzers daily.

Why HVAC Techs Are In Demand

Climate control isn't optional — and systems are getting more complex. The BLS projects 8% growth from 2024 to 2034, with about 40,100 openings per year. Rising temperatures, energy efficiency mandates, and the transition from older refrigerants to new-generation alternatives all create ongoing demand. HVAC technicians who specialize in heat pumps and energy-efficient systems are particularly sought after.

Work Environment

You'll work in homes, schools, hospitals, and commercial buildings — plus on rooftops where outdoor units are installed. The work involves crouching in attics, crawl spaces, and mechanical rooms. Summer attic work can be extremely hot; winter outdoor work can be cold. Most HVAC techs work full time, and schedules often include evenings and weekends during peak season.

What Carpenters Do

Carpenters construct, repair, and install building frameworks and structures made from wood and other materials. In residential construction, that means framing walls and roofs, installing doors and windows, building decks and stairs, hanging drywall, running trim and finish work, and sometimes concrete form-work. Carpentry is arguably the broadest of the building trades — it touches nearly every phase of a building project.

A Day in the Life

On a new-construction site, your morning might start with framing exterior walls — measuring and cutting 2x4s, nailing together wall sections on the deck, then raising them into place and bracing them plumb. Afternoon might shift to sheathing the walls with OSB and installing house wrap. On a remodel job, you might be tearing out an old kitchen, rebuilding the cabinet layout, and hanging new cabinets with precision measurements. Finish carpenters spend their days installing crown molding, baseboards, and custom shelving with meticulous attention to tight joints and clean lines.

Carpentry is deeply satisfying — you can literally see a building take shape from a flat slab to a completed home over the course of a project. You'll use everything from circular saws and framing nailers to hand planes and chisels.

Why Carpenters Are In Demand

Carpenters are the backbone of construction. With about 74,100 openings projected annually through 2034, demand is steady and broad — residential, commercial, remodel, and specialty markets all need skilled carpenters. The aging housing stock in the U.S. drives consistent remodeling work, and new residential construction continues, especially in growing areas.

Work Environment

Carpenters work on construction sites, in homes, and in workshops. The work is highly physical — standing, climbing, lifting, and kneeling for extended periods. You'll work outdoors in all weather conditions, and job sites change regularly. Most carpenters work full time; overtime, evenings, and weekends are common to meet construction deadlines.

What Welders Do

Welders use hand-held or remotely controlled equipment to permanently join metal parts together — or cut them apart. They work with processes like MIG (wire-fed gas shielded), TIG (precision gas tungsten arc), stick (shielded metal arc), and flux-core welding, each suited to different metals and applications. Welders read blueprints, calculate dimensions, inspect materials, and select the right filler metals, gas mixtures, and machine settings to produce joints that are stronger than the base material itself.

Welding shows up everywhere: structural steel for buildings, pipe for oil and gas, auto body repair, shipbuilding, aerospace components, farm equipment, and artistic metalwork. It's one of the most transferable skills in the trades — once you can weld, you can work in almost any industry.

A Day in the Life

In a fabrication shop, your morning might start by reviewing blueprints for a set of custom steel brackets. You measure and cut flat bar on a bandsaw, tack the pieces together in a jig to hold alignment, then lay down MIG welds on each joint — watching the puddle through your auto-darkening helmet to ensure full penetration with no porosity. After grinding the welds smooth, you check dimensions with calipers and mark them for powder coating.

In the afternoon, a structural project comes in: welding I-beams for a building frame. You switch to flux-core for the thicker material, working in multiple passes to build up the joint. Between runs, you chip slag and wire-brush the weld face. Other days might involve TIG welding thin-wall stainless pipe, stick welding in the field on a repair, or running a plasma cutter to fabricate parts from sheet metal.

Welding is physical and requires intense focus — your eyes are locked on a molten pool of metal at thousands of degrees. But there's genuine craft in it. A clean stack of dimes on a perfect bead is deeply satisfying.

Why Welders Are In Demand

About 45,600 welding positions open up each year, many from retirements. While overall growth is modest at 2%, the retirement wave is significant — the average welder is nearing 55 years old, and the workforce simply isn't replacing itself fast enough. Infrastructure spending (bridges, buildings, pipelines), renewable energy construction (wind towers, solar frames), and ongoing manufacturing all keep demand strong. Specialized welders — underwater, aerospace, pipeline — can command significant premiums.

Work Environment

Welders work in fabrication shops, construction sites, shipyards, refineries, and repair facilities. The work involves exposure to heat, bright arc light, fumes, and loud noise — all managed with proper PPE (helmet, gloves, leathers, respirator). You'll stand, kneel, and sometimes work overhead or in confined spaces. Many welders work full time; some manufacturing plants run two or three shifts. Overtime is common, especially in construction and pipeline work.

What CDL-A Drivers Do

Heavy and tractor-trailer truck drivers transport goods over long distances in vehicles with a gross vehicle weight rating (GVWR) exceeding 26,001 pounds. You'll operate combination vehicles — a tractor pulling one or more trailers — hauling everything from consumer goods and building materials to refrigerated food and hazardous materials. A Class A commercial driver's license (CDL-A) is required, and additional endorsements (HazMat, tanker, doubles/triples) unlock higher-paying specialty loads.

Trucking is the backbone of the American economy. Trucks move 72.7% of all domestic freight by tonnage, generating over $906 billion in annual revenue. If you see it in a store, a truck brought it there. CDL-A driving offers one of the fastest paths from zero experience to a middle-class income — many drivers are earning within weeks of completing training.

A Day in the Life

Over-the-road (OTR) driver: You wake up at 5 AM in your sleeper berth at a truck stop in Oklahoma. After a pre-trip inspection — walking around the rig checking tires, lights, air lines, coupling devices, and load securement — you log on to your ELD (electronic logging device) and head west on I-40. You've got 600 miles to cover today, delivering a load of consumer electronics to a distribution center in Albuquerque. You manage your 11-hour drive window carefully, stopping for fuel and a 30-minute break. At the receiver, you back into a dock, wait for unloading, get your paperwork signed, and check your dispatch app for the next load.

Regional/dedicated driver: You run a regular route between Kansas City and Dallas, home every weekend. You know the lanes, the shippers, the receivers. The work is more predictable — less adventure, more routine, better home time. Either way, the cab is your office: climate controlled, satellite radio, comfortable seat, and nothing but open road ahead of you.

Why CDL-A Drivers Are In Demand

This is one of the highest-volume career openings in the entire U.S. economy — about 237,600 positions per year. The trucking industry has faced a persistent driver shortage for years; the American Trucking Associations estimates the gap at 60,000–80,000 drivers. High turnover rates (especially in long-haul), an aging workforce, and growing freight demand all contribute. Many carriers are offering sign-on bonuses, tuition reimbursement, and first-year pay packages that would have been unheard of a decade ago.

Work Environment

OTR drivers spend days or weeks on the road, living in their truck's sleeper cab. Regional and local drivers may be home nightly or on weekends. The work involves long hours of sitting, loading dock wait times, and navigating traffic and weather. Federal Hours of Service regulations limit driving to 11 hours per day within a 14-hour window, with mandatory 10-hour rest breaks. The lifestyle requires independence, self-discipline, and comfort with solitude. It's not for everyone — but for those who love driving, the freedom of the open road is genuinely appealing.

What Diesel Technicians Do

Diesel service technicians inspect, repair, and overhaul trucks, buses, and equipment powered by diesel engines. These are the big rigs — Class 6 through Class 8 vehicles that haul freight, pour concrete, and move earth. You'll work on engines with 10 to 15 liters of displacement, transmissions with 10 to 18 speeds, air brake systems, hydraulic lifts, refrigeration units, and complex emissions aftertreatment systems (DPF, DEF, SCR).

Diesel technology has become extremely sophisticated. Modern trucks use electronic engine controls, telematics, automated manual transmissions, and emissions systems that rival the complexity of anything in the automotive world. If you like working on big, powerful machines and solving problems, diesel tech is an outstanding career.

A Day in the Life

You arrive at the fleet shop at 6 AM — trucks need to be ready to roll by 7. First up is a Freightliner Cascadia with a check engine light: you plug in the OEM diagnostic laptop, pull fault codes from the aftertreatment system, and find a failed NOx sensor. You replace it, perform a forced DPF regen, clear codes, and road test. The driver's back on the road by 7:30.

Mid-morning, a Kenworth T680 comes in for a DOT annual inspection. You go through the entire vehicle systematically: brakes (measure drum and shoe, check slack adjusters), suspension (kingpins, bushings, spring hangers), steering (tie rod ends, drag link), tires, lights, air system, frame — 150+ inspection points. After lunch, you're elbows-deep in an engine-out repair on a Peterbilt 389 — replacing a turbocharger that failed and sent metal through the intake. The work is physical and demanding, but the satisfaction of keeping these machines running is real.

Why Diesel Techs Are In Demand

About 26,500 diesel technician positions open up each year. The trucking industry moves 72.7% of all domestic freight by tonnage — and every one of those trucks needs maintenance. Fleet managers consistently rank technician shortage as a top concern. The average age of commercial trucks is increasing, which means more maintenance and repair work. And diesel emissions regulations (EPA 2010, GHG Phase 2) have made these vehicles far more complex to service, raising the skill bar and the pay.

Work Environment

Diesel techs work in truck dealership service bays, fleet maintenance shops, construction equipment yards, and mobile service trucks. The environment is noisier and more physical than auto work — you're dealing with components that weigh hundreds of pounds, working under vehicles on creepers or in pits, and handling heavy tools. Safety gear (steel-toes, gloves, hearing protection) is essential. Many shops run extended hours or 24/7 operations; evening and weekend shifts are common. Overtime is frequent and well-compensated.

What Quick Service Technicians Do

Auto detailers and lubrication/tire technicians handle the high-volume, entry-level service work that keeps vehicles running and looking their best. Detailers wash, clay bar, polish, wax, and protect vehicle exteriors and clean, condition, and protect interiors — from daily drivers to high-end collectibles. Lube and tire techs perform oil and filter changes, tire rotations, mount-and-balance, fluid top-offs, and multi-point inspections.

These are the on-ramp roles of the automotive industry. They're accessible with minimal training, provide immediate income, and — critically — they put you inside a shop where you can learn from experienced technicians and decide which direction to take your career.

A Day in the Life

As a detailer: You arrive at the detail shop at 8 AM with three vehicles scheduled. First is a full interior/exterior detail on a black BMW — wash, decontaminate, clay bar, compound to remove swirl marks, polish, and apply ceramic sealant. The interior gets steam-cleaned carpets, leather conditioning, and glass. It takes about 4 hours and the result is stunning. Your afternoon includes a basic wash-and-wax on a minivan and a pre-sale detail for a used car dealer.

As a lube/tire tech: You're in a quick-lube bay performing oil changes and tire rotations at a pace of 6–8 per hour across a team. Each vehicle gets a multipoint inspection: check tire tread and pressure, top off fluids, inspect belts, hoses, and air filter, and note any issues for the customer. When a car comes in for new tires, you mount, balance, and torque to spec. The work is fast-paced and repetitive, but you're developing fundamental automotive skills with every vehicle.

Why These Roles Matter

Quick service and detailing positions are the proving ground for the automotive industry. They're how most technicians start — and they're always hiring. For students exploring whether automotive work is right for them, these 20-hour Peaslee Tech programs are the lowest-risk way to find out. You invest less than $300 and one week of time to gain skills that are immediately employable. Many students use these programs as a stepping stone into the full Auto Service Technician program.

Work Environment

Detailers work in dedicated detail shops, car washes, dealership detail departments, and mobile detailing operations. The work is physical — lots of bending, scrubbing, and polishing — but the environment is generally clean and pleasant. Lube and tire techs work in quick-lube facilities, tire shops, and dealership express service departments. Both roles are typically daytime hours with some weekend work. The pace can be fast, especially in high-volume shops.

What Robotics Technicians Do

Robotics and automation technicians install, program, maintain, and troubleshoot the robotic arms, automated assembly lines, conveyor systems, and programmable logic controllers (PLCs) that run modern factories. You're the person who keeps a $500,000 robotic welding cell running — diagnosing faults, replacing servo motors, tuning motion parameters, and writing PLC ladder logic to coordinate the entire production line.

This is the cutting edge of manufacturing. As factories adopt Industry 4.0 technologies — collaborative robots (cobots), vision systems, IoT sensors, and AI-driven quality inspection — the technicians who can install and maintain these systems are among the most valuable people on the shop floor.

A Day in the Life

Your morning might start with scheduled preventive maintenance on a 6-axis robotic palletizer — greasing joints, checking cable harnesses, calibrating the tool center point, and backing up the robot's program. At 10 AM, an alarm fires on a packaging line: a proximity sensor on the conveyor has failed. You pull up the PLC program on your laptop, trace the logic to identify the faulted input, swap the sensor, and have the line running again in 30 minutes.

After lunch, you're part of a team commissioning a new robotic welding cell. You help set the robot's home position, teach weld paths by jogging the arm through each point, configure the welder interface, and run test cycles — adjusting travel speed and torch angle until the weld quality meets spec. The work blends mechanical skills (wrenches and multimeters) with digital skills (programming and networking).

Why Robotics Techs Are In Demand

The BLS projects 13% growth for industrial machinery mechanics and related automation roles through 2034 — more than four times the national average. This is one of the fastest-growing occupations in the country. Factories are investing billions in automation, but robots don't maintain themselves. Every robot installed creates demand for technicians who can keep it running. About 54,200 openings per year are projected, and employers routinely report difficulty finding qualified candidates.

Work Environment

Robotics techs work in manufacturing plants, distribution centers, food processing facilities, automotive plants, and anywhere automation is deployed. You'll wear steel-toed boots, safety glasses, and hearing protection. The work involves a mix of physical tasks (crawling under machines, pulling wire) and desk work (programming, data analysis). Most work full time; on-call and overtime are common since downtime is extremely expensive.

What Cosmetologists Do

Cosmetologists provide haircutting, coloring, styling, chemical treatments, and other beauty services. A full cosmetology license (which Kansas requires 1,500 training hours to earn) also qualifies you for skincare, makeup application, and nail services — though most cosmetologists specialize in hair. You’ll learn cutting techniques, color theory, chemical processing (perms, relaxers, keratin treatments), updos and styling, sanitation, and the business side of running a chair or salon.

This is one of the most entrepreneurial careers in the trades. Many cosmetologists start as employees, build a clientele, then either rent a booth, open their own salon, or go mobile. The earning potential is heavily influenced by your skill, reputation, location, and business savvy — official BLS numbers significantly undercount actual earnings because they don’t capture self-employed income or tips.

A Day in the Life

Your first client arrives at 9 AM for a full highlight and cut. You consult on the look she wants, section her hair, apply foils with a balayage technique, process, tone, wash, cut, and blowdry — two hours of focused, creative work. Next is a men’s fade with a beard trim, followed by a corrective color (a client who went box-dye and needs rescue). After lunch, you have a bridal consultation — trial updo and makeup for a wedding next month.

Between clients, you respond to booking requests on your Instagram, restock your color inventory, and clean your station. Your last appointment is a teenager getting her first real haircut — the excitement is contagious. By 6 PM, you’ve served 6–8 clients, earned your service fees plus tips, and no two days look exactly the same. The creative expression, personal connections, and schedule flexibility are what keep cosmetologists in the career for decades.

Why Cosmetology Is Growing

The BLS projects 5% growth for cosmetologists through 2034, with about 84,200 openings per year — one of the highest volumes of any occupation. People always need haircuts, and demand for specialized services (color correction, extensions, textured hair care, bridal) continues to grow. Social media has transformed the industry, allowing talented stylists to build massive followings and premium pricing. Automation can’t replace the human touch of a great stylist.

Work Environment

Cosmetologists work in salons, barbershops, spas, hotels, resorts, and their own studios. The work requires standing for long periods and involves exposure to chemicals (color, perms) — ventilation and protective equipment are important. Schedules are flexible but often include evenings and weekends when clients are available. Many cosmetologists work part-time by choice, and the career is exceptionally accommodating for parents, students, and those building a side business.
