FAQs (Frequently Asked Questions)

What is the Agricultural and Biosystems Engineer Licensure Examination?

The Agricultural and Biosystems Engineer Licensure Examination (ABELE) is a national board exam administered by the Professional Regulation Commission (PRC) in the Philippines. It evaluates whether graduates of Agricultural and Biosystems Engineering or Agricultural Engineering programs have the technical competence, ethical grounding, and practical understanding required to practice as licensed engineers in fields such as farm machinery, irrigation, post-harvest technology, environmental management, and biosystems engineering.

Who is eligible to take the ABELE?

You are eligible to take the exam if you hold a bachelor’s degree in Agricultural and Biosystems Engineering or Agricultural Engineering from a PRC-recognized institution. Your program should include board-related subjects such as farm machinery, soil and water engineering, post-harvest technology, agricultural structures, and environmental management. You must also be of good moral character and have no conviction involving moral turpitude, as certified by your school or local authorities.

How often is the exam given and where is it held?

The ABELE is typically conducted once a year, although the exact frequency and dates depend on PRC’s official schedule and resolutions. Examinations are held in selected PRC testing centers, which may include major cities such as Manila and regional hubs where there is sufficient demand. Applicants choose their preferred testing center when they register through the PRC Licensure Examination and Registration Information System (LERIS).

How do I apply for the ABELE through PRC?

To apply, you must first create or update your account on the PRC LERIS website. After completing your profile and uploading a compliant ID photo, you can select the Agricultural and Biosystems Engineer Licensure Examination from the available list and choose your preferred testing center and schedule. Then you pay the examination fee through PRC’s payment channels. On your appointment date, you must appear at your selected PRC office with your documentary requirements for verification and issuance of your Notice of Admission (NOA).

What are the main subjects covered in the exam?

The exam is usually divided into two broad subject areas. The first covers farm machinery and power, agricultural mechanization, agricultural buildings and structures, post-harvest facilities, environmental management, and renewable energy systems. The second focuses on land and water resources engineering, which includes hydraulics, irrigation design, soil and water conservation, drainage, watershed management, and soil classification. All questions are typically multiple-choice and require both computation skills and conceptual understanding.

What is the passing rate and grading system?

To pass the ABELE, you must obtain a general weighted average of at least 70 percent, with no rating lower than 50 percent in any subject. This means that consistently poor performance in one subject can cause you to fail even if your overall score appears high. PRC typically releases the official list of passers within several working days after the examination, along with the names of topnotchers and top-performing schools. Exact pass rates vary by year, depending on the examinees’ performance.

How should I prepare effectively for the ABELE?

Effective preparation combines reviewing core concepts, solving many practice problems, and simulating test conditions. Start by revisiting your university notes and standard textbooks for machinery, irrigation, soil and water conservation, post-harvest technology, and environmental engineering. Dedicate regular blocks of time for computation drills, especially for hydraulics, pump design, tractor power, and irrigation scheduling. Many examinees also enroll in review centers or join peer study groups to gain access to mock exams, structured review plans, and coaching from licensed engineers.

Do I need to enroll in a review center to pass?

Enrolling in a review center is not mandatory but can be beneficial, especially if you prefer guided study, scheduled lectures, and curated materials. Review centers offer organized coverage of topics, regular quizzes, and simulated board exams. However, many examinees pass the ABELE through self-study, especially if they are disciplined, have strong fundamentals from their university training, and use high-quality review materials. Your choice should depend on your learning style, budget, and available time before the exam.

What calculators and materials are allowed during the exam?

PRC allows only non-programmable calculators that comply with its latest guidelines, so it is important to check the current list of permitted models before exam day. You are usually required to bring your Notice of Admission, a valid government-issued ID, pencils, a black ballpen, and a clear plastic envelope. Scratch papers are typically provided by the examination room proctors. Unauthorized materials, such as notes or communication devices, are strictly prohibited and may lead to disqualification.

What should I wear and bring on exam day?

PRC generally requires examinees to follow a professional dress code, typically a white collared shirt or blouse and dark pants or skirt, with closed shoes. You should bring your Notice of Admission, a valid ID, allowed calculator, pencils, ballpen, and basic personal items such as snacks and water in clear containers if permitted. Arrive early at the testing center to avoid stress and to give yourself time to locate your assigned room and seat.

What happens if I fail the exam? Can I retake it?

If you fail the ABELE, you can apply to retake it in the next scheduled examination cycle, subject to PRC’s rules and deadlines. Many repeat takers adjust their strategy by doing a detailed review of their weak areas, taking more practice tests, or enrolling in a review center. Failing once does not prevent you from becoming a licensed engineer; what matters is learning from the experience, improving your preparation, and approaching the next attempt with a more focused and realistic study plan.

What career opportunities are available after passing the ABELE?

Passing the ABELE and becoming a licensed Agricultural and Biosystems Engineer opens doors in both public and private sectors. You can work in farm systems design, irrigation and drainage projects, post-harvest and food processing facilities, environmental and waste management, renewable energy systems, and agricultural equipment companies. Employment opportunities are available in government agencies, agribusiness firms, research institutions, consulting firms, and development projects. With experience, you may also establish your own engineering consultancy or agri-tech enterprise.
