The Professional Regulation Commission (PRC) announces the result of the first phase of this years’ Licensure exam for mechanical engineers. Out of 1134 examinees, 601 passed the said exam (53%). Registration for the issuance of Professional Identification Card (ID) and Certificate of Registration will start on Monday, April 5 until Wednesday, April 21, 2010. Requirements for registration are as follows: Duly accomplished Oath of Professional (Panunumpa ng Propesyonal) form Current Community Tax Certificate (cedula), 2 pieces passport size picture (colored with white background and complete nametag) 1 piece 1x1 picture (colored with white background and complete nametag) 2 sets of metered documentary stamps 1 short brown envelope with name and profession For MECHANICAL ENGINEER Initial Registration Fee of P600 Annual Registration Fee of P450 for 2010-2013 For CERTIFIED PLANT MECHANIC Initial Registration Fee of P450 and Annual Registration Fee of P420 for 2010-2013 Th

The Professional Regulation Commission (PRC) successfully administered the March 2010 Mechanical Engineering board examination to the qualified examinees. It was held last Saturday and Sunday, March 27 and 28 respectively. This new schedule is actually a month earlier than the previous one. The exam is divided into three main categories or topics, Mathematics (Economy, Laws, and Engineering Sciences), Machine Design (and machine Shop Practices), and Power (Power and Industrial Plant Engineering). The board of mechanical engineering (BME), as directed by RA 8495 or The Philippine Mechanical Engineering Act of 1998 , is the sole body in-charge of making the exam questionnaires. This year’s board members are the following. Alfredo Y. Po (Chairman) Vicente B. Vosotros (Member) Leandro A.
