1.1 MELE Facts, RA 8495 & Board Organization

Quick Answer: The Mechanical Engineering Licensure Examination (MELE) is the national licensure examination administered by the Professional Regulation Commission (PRC) and the Board of Mechanical Engineering under Republic Act No. 8495 (The Philippine Mechanical Engineering Act of 1998). To pass, examinees must achieve a General Weighted Average (GWA) of at least 70% with no individual board subject rating falling below 50%. The exam evaluates three major subjects: Machine Design, Materials & Shop Practice (30%), Power & Industrial Plant Engineering (35%), and Mechanical Engineering Ethics, Allied Subjects & Industrial Plant Design (35%).

Republic Act No. 8495: The Statutory Basis of Mechanical Engineering Practice

Republic Act No. 8495, officially titled the "Philippine Mechanical Engineering Act of 1998", was signed into law on February 12, 1998, repealing Commonwealth Act No. 294. RA 8495 establishes the legal framework for the regulation, licensing, and professional practice of mechanical engineering across the Philippines.

The legislative policy of RA 8495 mandates the state to supervise and regulate the practice of mechanical engineering to safeguard life, health, property, and public welfare. It defines the exact scope of mechanical engineering practice, sets up the administrative machinery for professional licensure, and establishes clear qualifications and responsibilities for all mechanical engineering practitioners across commercial, industrial, and institutional sectors.

Organization and Powers of the Board of Mechanical Engineering

The Board of Mechanical Engineering (BME) is an administrative body created under RA 8495, operating under the administrative supervision and executive control of the Professional Regulation Commission (PRC).

Composition and Appointment

The Board consists of a Chairman and two (2) Members, appointed by the President of the Philippines from a list of three (3) recommendees per vacancy submitted by the PRC. These recommendees are chosen from a list of five (5) nominees per vacancy submitted by the Accredited Integrated Professional Organization (AIPO) of Mechanical Engineers—the Philippine Society of Mechanical Engineers (PSME).

Qualifications of Board Members

Under Section 5 of RA 8495, each Board member must satisfy the following statutory requirements at the time of appointment:

• Be a natural-born citizen and resident of the Philippines.
• Be at least thirty-five (35) years of age.
• Hold a valid Certificate of Registration and Professional Identification Card as a Professional Mechanical Engineer (PME), with active practice for at least ten (10) years prior to appointment.
• Not be a faculty member of any school, college, or university where a degree in mechanical engineering is conferred, nor have any pecuniary interest in any review center or institution conducting review classes for board examinations.
• Must not have been convicted of any offense involving moral turpitude.

Board members serve a term of three (3) years and may be reappointed for another three-year term.

Categories of Mechanical Engineering Practice

RA 8495 establishes three distinct professional categories for mechanical engineering practice in the Philippines, each defined by specific educational qualifications, experience levels, and legal scopes of authority:

MELE Subject Breakdown, Weights, and Syllabus Coverage

The Mechanical Engineering Licensure Examination (MELE) is administered over two consecutive days and tests examinees across three major weighted subjects:

+-----------------------------------------------------------------------------------+
|                           MELE SUBJECT BREAKDOWN & WEIGHTS                        |
+-----------------------------------------------------------------------------------+
|  Subject 1: Machine Design, Materials & Shop Practice (MDME)          -->  30%    |
|  Subject 2: Power & Industrial Plant Engineering (PIPE)               -->  35%    |
|  Subject 3: ME Ethics, Allied Subjects & Plant Design (MEEBES)        -->  35%    |
+-----------------------------------------------------------------------------------+

1. Machine Design, Materials & Shop Practice (MDME) — 30% Weight

• Kinematics & Dynamics of Machinery: Linkages, cams, gears, velocity and acceleration analysis, flywheels, governors.

• Internal Combustion Engines & Gas Turbines: Engine cycles, performance parameters, fuel injection systems, supercharging, gas turbine power plants.
• Steam Power Plants & Auxiliaries: Boilers (fire-tube, water-tube), steam turbines, condensers, feedwater heaters, economizers, air preheaters, draft systems.
• Refrigeration & Air Conditioning (RAC): Vapor compression and absorption cycles, psychrometrics, cooling load calculations, air distribution, duct sizing, chillers.
• Fluid Machinery & Piping: Centrifugal and positive displacement pumps, fans, blowers, air compressors, hydraulic turbines, ASME piping standards.
• Hydroelectric & Non-Conventional Energy: Hydroelectric power plant design, solar, wind, geothermal, and biomass energy conversion systems.

3. ME Ethics, Allied Subjects & Industrial Plant Design (MEEBES) — 35% Weight

• Engineering Laws & Ethics: RA 8495, ME Code of Ethics, PSME Code, contracts, obligations, professional liabilities, and labor laws.
• Engineering Economics & Management: Present worth, annual cost, rate of return, depreciation methods, breakeven analysis, project scheduling.

The 70% GWA & 50% Subject Rating Passing Rule

Passing the MELE requires satisfying a dual-criterion grading rule evaluated by the PRC computer system:

1. General Weighted Average (GWA): The examinee must achieve a final GWA of 70% or higher, calculated using the official weighted formula:

$\text{GWA} = (\text{MDME Score} \times 0.30) + (\text{PIPE Score} \times 0.35) + (\text{MEEBES Score} \times 0.35)$

1. Subject Floor Rule: The examinee must not score below 50% in any individual subject.

Illustrative Grading Scenarios

• Candidate A: MDME = 72%, PIPE = 74%, MEEBES = 76%. $\text{GWA} = (72 \times 0.30) + (74 \times 0.35) + (76 \times 0.35) = 21.6 + 25.9 + 26.6 = 74.1%$. RESULT: PASSED (GWA $\ge 70%$ and all subject ratings $\ge 50%$).
• Candidate B: MDME = 90%, PIPE = 85%, MEEBES = 48%. $\text{GWA} = (90 \times 0.30) + (85 \times 0.35) + (48 \times 0.35) = 27.0 + 29.75 + 16.8 = 73.55%$. RESULT: FAILED (GWA exceeds 70%, but MEEBES rating of 48% violates the 50% floor rule).
