📢 RME SEPTEMBER 2026 EXAM ALERT: The Professional Regulation Commission (PRC), through the Board of Mechanical Engineering, will administer the next Mechanical Engineer Licensure Examination on Saturday and Sunday, September 26–27, 2026 — about three months away. The Mechanical Engineer (ME) Licensure Examination grants the right to design, supervise, and certify mechanical systems for buildings, power plants, manufacturing, HVAC, and industrial operations across the Philippines. This guide covers the official three-subject syllabus, a focused 12-week study plan, the recommended Filipino reviewers, and the strategies that consistently produce passers and topnotchers in one of the more technically demanding PRC board exams.
Understanding the RME Examination
The Mechanical Engineer Licensure Examination is administered by the PRC Board of Mechanical Engineering under Republic Act No. 8495 (Philippine Mechanical Engineering Act of 1998). Passing the ME exam grants the title of Registered Mechanical Engineer (RME), which is required for signing and sealing mechanical designs, supervising mechanical installations above certain capacity thresholds, and signing mechanical plans for building permits, factory operations, boilers, and pressure vessels.
To pass, you must achieve a general weighted average of 70%, with no grade below 50% in any subject. Recent batches have shown passing rates between 50% and 70%, reflecting the technical depth of the exam but also that disciplined preparation reliably converts to a passing score.
The Board of Mechanical Engineering also administers the Certified Plant Mechanic (CPM) examination (a sub-professional credential) and the Professional Mechanical Engineer (PME) examination (a higher credential requiring four years of post-licensure practice). This guide focuses on the entry-level RME.
The Three RME Subjects (with Weights)
The ME Licensure Examination consists of three subjects spread across two days, with each subject typically running about 5 hours with 100 multiple-choice items. The official Board syllabus assigns the following coverage and weights:
- Subject 1 — Mathematics, Engineering Economics, and Basic Engineering Sciences (30%): algebra, plane and spherical trigonometry, analytic and solid geometry, differential and integral calculus, differential equations, advanced engineering mathematics, statistics, engineering economy, statics, dynamics, mechanics of materials (strength of materials), thermodynamics, fluid mechanics, heat transfer.
- Subject 2 — Industrial and Power Plant Engineering (35%): power plant engineering (steam, diesel, geothermal, hydro, gas turbine, combined cycle), internal combustion engines, refrigeration and air conditioning (HVAC), industrial plant engineering, plant utilities, energy management, environmental engineering, control systems, instrumentation.
- Subject 3 — Machine Design, Materials, and Shop Practice (35%): machine elements (shafts, gears, bearings, belts, chains, springs, fasteners, brakes, clutches), strength of machine parts, fluid power (hydraulics and pneumatics), engineering materials (ferrous and non-ferrous metals, polymers, ceramics), heat treatment, manufacturing processes (machining, casting, welding, forming), metrology, and machine shop safety.
Power Plant Engineering and Machine Design carry the heaviest weights at 35% each — together they account for 70% of your total score. Strong preparation in these two areas is the single most reliable predictor of a passing GWA.
Your 12-Week Study Roadmap
Weeks 1–2 (Early-Mid June): Diagnostic and Mathematics
Take a full-length mock RME in your first week to identify your weakest subject. Then dedicate two weeks to Mathematics and Engineering Economy — the spine of Subject 1 and a recurring tool across the other two subjects. Drill algebra, trigonometry, calculus (especially differential and integral), differential equations, and basic statistics. For Engineering Economy, master present worth, annual worth, rate of return, payback period, and depreciation methods. Target 30 items per day.
Weeks 3–4 (Mid-Late June): Basic Engineering Sciences
Master the foundational sciences: Statics (equilibrium, friction, centroids), Dynamics (kinematics, kinetics, work-energy, impulse-momentum), Strength of Materials (stress, strain, torsion, beams, columns), Thermodynamics (first and second law, cycles, properties of pure substances), and Fluid Mechanics (Bernoulli, continuity, friction in pipes). These directly feed Subjects 2 and 3.
Weeks 5–7 (July): Power Plant and Industrial Plant Engineering
Spend three weeks on Subject 2. Cover steam power plants (Rankine cycle, boilers, turbines, condensers, feedwater systems), diesel power plants, gas turbine and combined cycle plants, hydroelectric basics, geothermal, internal combustion engines (Otto and Diesel cycles), refrigeration and HVAC (vapor compression cycle, psychrometrics, cooling load calculation, duct sizing), and industrial plant engineering (plant layout, utilities, energy audits). Target 40 items per day with case-based reasoning.
Weeks 8–10 (August): Machine Design, Materials, and Shop Practice
Spend three weeks on Subject 3. Master the design of machine elements — shafts under combined loading, gears (spur, helical, bevel, worm), bearings (rolling and journal), belts and chains, springs, fasteners, brakes and clutches. Cover engineering materials and heat treatment, manufacturing processes, fluid power systems (hydraulics and pneumatics), and the basics of metrology and shop safety. Target 40 items per day.
Weeks 11–12 (Early-Mid September): Full Mocks and Code Review
Take two full-length mock RMEs (one per weekend) under timed 5-hour-per-subject conditions. Review every wrong answer with the underlying formula or theory. The final week is for the Philippine Mechanical Engineering Code, the Philippine Society of Mechanical Engineers (PSME) Code, R.A. 8495 and its IRR, the National Building Code (P.D. 1096) provisions on mechanical works, and the ASHRAE Handbook highlights for HVAC. Stop learning new content the week before the exam.
Recommended Reviewers and References
- Capote Mechanical Engineering Board Exam Reviewer — the long-standing Filipino gold standard, with comprehensive coverage across all three subjects.
- Vergel Power Plant Engineering Reviewer — deep on Subject 2 with detailed thermodynamic cycles and worked examples.
- Faires — Design of Machine Elements — the classical reference for Subject 3 machine design. Still widely used in Philippine ME programs.
- Shigley’s Mechanical Engineering Design — modern alternative to Faires with updated formulas.
- Sta. Maria Refrigeration and Air Conditioning — the standard local reference for HVAC items.
- Frankel Facilities Engineering and Management Handbook — for industrial plant engineering items.

- R.A. 8495 (Philippine Mechanical Engineering Act) and its IRR — ethics and practice questions are often verbatim.
- ASHRAE Handbook — Fundamentals — gold standard for HVAC calculation methods.
Top Test-Taking Strategies for the RME
- Answer easy items first. With 100 items in 5 hours per subject, you have 3 minutes per item. Don’t lose more than 5 minutes on any one problem in the first pass.
- Estimate before computing. Many RME answer choices are an order of magnitude apart — a rough estimate eliminates impossible options instantly.
- Convert units carefully. Mix-ups between English (BTU, lb, ft) and SI (kJ, kg, m) units cause more wrong answers than incorrect formulas. ME items routinely test both systems.
- Memorize the steam tables format. You will get steam tables on the exam — practice extracting saturated and superheated property values quickly and accurately.
- Bring at least two calculators. Battery dies happen. The PRC permits non-programmable, non-printing calculators only — Casio FX-991 series is the gold standard.
- For machine design, draw the free body diagram. Always. Even simple problems are easier when you sketch the load path.
- Never leave a blank. There is no penalty for wrong answers. Always shade something — a blind guess gives you a 25% chance.
Exam-Day Checklist
- Notice of Admission (NoA), printed for each day
- Original PRC-recognized ID with photo and signature
- Two or more non-programmable scientific calculators (Casio FX-991, Sharp EL-W516, or equivalent)
- Spare batteries for your calculator
- At least two black ballpoint pens (no erasable ink)
- Several No. 2 pencils with eraser for scratch work
- Long brown window envelope (PRC requirement)
- Transparent water bottle and high-protein snacks (5-hour subjects demand sustained focus)
- Analog watch (no smartwatches inside the testing room)
- Decent shoes and a jacket (testing rooms are heavily air-conditioned)
Arrive at the testing center by 6:30 AM. Visit the venue the day before if possible — weekend morning traffic and parking around major PRC testing centers can wreck your nerves.
Common Mistakes That Cost Eligibility
- Bringing a programmable calculator (instant confiscation and disqualification).
- Underestimating Engineering Economy — it consistently appears in Subject 1 and is worth easy points if mastered.
- Skipping the Philippine Mechanical Engineering Code — code-based items appear in every batch.
- Confusing thermodynamic cycle states (1-2-3-4) and the direction of the cycle on T-s and P-v diagrams.
- Mixing up gear nomenclature (module vs diametral pitch, pressure angle conventions).
- Cramming the night before instead of resting — 5 hours of computation per subject demands stamina.
After the Exam
The PRC has historically released ME Licensure results in 3 to 5 working days post-exam. For September 2026, target release is on or before October 2, 2026. Passers should monitor the PRC LERIS portal for their registration appointment and the schedule of the mass oath-taking ceremony. Once registered as a Registered Mechanical Engineer (RME), you can sign and seal mechanical designs, pursue specialized practice in HVAC, power plants, manufacturing, and energy management, or apply for senior positions in private firms, government agencies (DOE, DPWH, DENR, Bureau of Energy Efficiency), and the construction sector.
The PSME (Philippine Society of Mechanical Engineers) is the official accredited professional organization — joining unlocks Continuing Professional Development (CPD) units required for license renewal every three years and connects you to the broader Filipino mechanical engineering community.
A Final Word for Future RMEs
The RME is rigorous because mechanical engineering touches almost every productive sector of the Philippine economy — from the power plants that keep the grid running, to the HVAC systems that cool every modern building, to the manufacturing lines that produce the goods Filipinos depend on every day. Three months of structured preparation, daily problem solving, and disciplined code review are enough to pass. Trust your training, manage your stamina across the two demanding test days, and remember why you chose this profession. The Philippines is industrializing, the energy transition is accelerating, and the country needs more well-prepared mechanical engineers ready to design and operate the systems of the next decade.
Good luck, future Registered Mechanical Engineer. We’re rooting for you.
