How to become a chemical engineer

1. 1Take chemistry, physics and calculus in high school

   Time: 4 years (high school)Sources 1

   Chemical engineering programs expect you to start calculus and college chemistry in your first semester, so take the most advanced math and science your school offers: chemistry, physics, biology, and math through precalculus or calculus. AP or dual-enrollment chemistry and calculus can free up space in a crowded degree plan.

2. 2Earn a bachelor's degree in chemical engineering

   Time: 4 years (about 5 with co-op)Cost: $12,456/yr median public in-state tuitionSources 4, 1, 7

   Pick a program accredited by ABET's Engineering Accreditation Commission; graduates of ABET-accredited engineering programs can become licensed PEs in every state through the FE and PE exams and work experience. After general chemistry, organic chemistry, physics and calculus through differential equations, you take mass and energy balances, thermodynamics, fluid flow, heat and mass transfer, reaction engineering and process control. Most programs end with a plant design project done in a team.

3. 3Get plant or lab experience through co-ops or internships

   Time: 1-3 summers or co-op terms during schoolCost: Usually paidSources 1

   Employers in chemicals, refining, pharmaceuticals and food processing often fill entry-level jobs from their own interns and co-op students. A co-op usually alternates semesters of school with full-time paid work, which can add a year but gives you real process engineering experience. Undergraduate research in a professor's lab is another option for students aiming at research and development work or graduate school.

4. 4Take the FE Chemical exam (optional)

   Time: Senior year or soon after graduationCost: $225 (2026)Sources 2, 5

   The NCEES Fundamentals of Engineering exam is a computer-based test with 110 questions in a 6-hour appointment, given at Pearson test centers. Chemical engineering students take the Chemical version. It is designed for students close to finishing an accredited engineering degree, so taking it while coursework is fresh makes sense. Many chemical engineers in manufacturing never take it, but it keeps the PE option open.

5. 5Start work as a process, design or research engineer

   Time: First years on the jobCost: Paid workSources 1

   Common first jobs are process engineer at a plant, project engineer at a design firm, or development engineer in a lab or pilot plant. Expect to learn the specific process, its safety systems and its data tools from senior engineers and operators. Moving into supervising engineers or managing a plant usually takes several years of this experience.

6. 6Earn a PE license if your work calls for it

   Time: About 4 years of experience, then the examCost: $400 exam fee (2026) plus state feesSources 3, 5, 6

   Most states require about four years of progressive engineering experience before the PE exam or license. The PE Chemical exam has 80 questions in a 9-hour appointment and is offered year-round at Pearson centers. You then apply to your state board with your results and verified experience. The license matters most for consultants and engineers who seal designs or serve the public directly.

Programs, tuition and graduates’ earnings

U.S. Department of Education, College Scorecard (most recent cohorts, released 2026-10-15). Scorecard groups programs by 4-digit field, so a row can include related programs. Tuition is the median published undergraduate tuition and fees of the colleges offering the program (shown only for undergraduate credentials); debt is the median of programs’ median federal loan debt at completion; earnings are the national median for the field and credential four years after completion.

Requirements differ by state. Check your state’s rules in the CareerOneStop License Finder (U.S. Department of Labor) before you enroll.

Thermodynamics and transport math

Sizing a column or heat exchanger means solving mass, energy and heat-transfer balances, often with calculus and numerical methods.

Process safety judgment

Chemical engineers set the limits for pressure, temperature and reactive materials, and a bad call can cause a fire, release or explosion.

Data analysis

Troubleshooting a unit means sifting through months of process data to find the variable that changed.

Process simulation software

Designs and plant changes are tested in simulation and CAD tools before money is spent on equipment.

Working with operators and other engineers

Fixes only stick when the operators running the plant and the mechanical and controls engineers understand and agree with them.

O*NET 31.0 rates these skills as most important for the occupation: science, critical thinking, reading comprehension, active learning, mathematics.

Pay above the all-jobs median vs. cost

Low: 4 years x College Scorecard median public in-state tuition for chemical engineering bachelor's programs, $12,456 = $49,824, plus the NCEES FE exam ($225) and PE Chemical exam ($400). High: 5 years at the same tuition, for students who take 5 years (co-op or a combined bachelor's-master's program), $62,280, plus the same exam fees. Not included: campus fees, books, housing, state license fees and review courses. Private universities cost far more; the median federal loan debt for these graduates is $21,524. The exams are optional, so a degree-only path costs $625 less.

Rough guide only: ignores taxes, aid, interest and earnings given up during training. How we calculate it.

• Engineering manager or technical lead

  Usually takes several years of experience, often under a senior engineer, before leading engineers and technicians or managing an engineering group.

• Plant or operations manager$105,770 median

  Process engineers who learn production, maintenance and budgets can move into running a unit or a whole plant; some add an MBA.

• Project manager$102,320 median

  Engineers at design firms and on plant expansions often move into leading capital projects; some earn a PMP certification.

• Mechanical engineer$104,110 median

  Engineers who gravitate to equipment design and reliability can shift toward mechanical roles, though some employers want a mechanical degree for design work.
