FAQs (Frequently Asked Questions)

What is the Geologist Licensure Examination?

The Geologist Licensure Examination is a national board exam administered by the Professional Regulation Commission (PRC) for geology graduates who want to become licensed and legally practice as professional geologists. It assesses your understanding of general geology, petrology and mineralogy, and applied geology, including geohazards, resource exploration, and engineering and environmental applications.

Who is eligible to take the Geologist Licensure Examination?

You are generally eligible if you hold a bachelor’s degree in Geology or a related program recognized by the Commission on Higher Education (CHED). You must present your Transcript of Records, birth certificate, valid ID, photos, and other standard PRC requirements. Foreign graduates may need to secure equivalency or validation documents as required by Philippine regulations.

How do I apply for the exam through PRC?

Applications are usually processed online through the PRC Licensure Examination and Registration Information System (LERIS). You need to create an account, fill in your personal and academic details, upload the required documents, choose your examination schedule and testing center, pay the examination fee, and then print your application form and Notice of Admission. Always refer to the latest PRC announcements for updated procedures.

What subjects are included in the exam coverage?

The exam typically covers three main areas: General Geology, Petrology and Mineralogy, and Applied Geology. General Geology focuses on earth processes, geomorphology, structural geology, stratigraphy, and paleontology. Petrology and Mineralogy emphasize rock and mineral identification, classification, and properties. Applied Geology covers engineering geology, hydrogeology, environmental geology, economic geology, geological mapping, and geohazard assessment.

What is the usual format and duration of the exam?

The Geologist Licensure Examination is usually administered over multiple days, with each major subject assigned its own session. The questions may include problem-solving items, essay-type questions, map interpretation, and diagram-based problems. You will be given several hours per subject, so effective time management and a clear answer structure are important for completing the exam on time.

What rating do I need in order to pass?

To pass the Geologist Licensure Examination, you typically need a general weighted average of at least seventy-five percent (75%), with no rating below fifty percent (50%) in any of the three major subjects. Failing to meet the required average or getting a very low score in one subject can result in failing the entire examination, even if your other scores are relatively high.

How long should I prepare before taking the exam?

Most successful examinees prepare seriously for at least four to six months before the exam. During this period, it is advisable to review your undergraduate notes, focus on core geology concepts, answer practice questions, and work on mapping and interpretation exercises. Your ideal preparation time may vary depending on your academic background, work experience, and how long ago you finished your degree.

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

Enrolling in a review center is not mandatory, but many candidates choose to do so for structure and guidance. Review centers can provide updated review materials, mock exams, and insights into common board exam patterns. However, it is still possible to pass through self-study, provided you follow a disciplined review plan, use reliable references, and practice regularly with past or sample questions.

What materials and references are recommended for reviewing?

Commonly used review materials include standard geology textbooks in general geology, structural geology, mineralogy, petrology, and applied fields such as hydrogeology and engineering geology. Some examinees also use lecture notes from university courses, review center handouts, geology atlases, geological maps, and online open-access resources. It helps to build a focused reading list rather than trying to study too many books superficially.

What should I bring and remember on exam day?

On exam day, bring your Notice of Admission, valid government-issued ID, several sharpened pencils, a good eraser, and an approved calculator if allowed by PRC rules. Arrive early at the testing center to avoid stress from traffic or unexpected delays. Read instructions carefully, manage your time per question, keep diagrams neat and labeled, and remain calm even if you encounter difficult items.

What happens after I pass the Geologist Licensure Examination?

If you pass, PRC will announce the list of successful examinees and issue instructions for the oath-taking ceremony. After taking your professional oath, you can claim your Professional Identification Card (PRC ID) and Certificate of Registration. You may then legally practice as a Registered Geologist in the Philippines and apply for positions in mining, engineering, environmental consulting, government agencies, research institutions, and other geology-related sectors.

What career paths and opportunities are available for licensed geologists?

Licensed geologists may work as exploration geologists, hydrogeologists, engineering or environmental geologists, geohazard specialists, or consultants in mining, infrastructure, and development projects. There are also opportunities in government offices dealing with natural resources and hazard management, as well as in universities and research institutions. With experience, geologists can advance to senior technical positions, project leadership roles, or management-level posts in local and international companies.

Can I work abroad after becoming a licensed geologist in the Philippines?

Many Filipino geologists eventually pursue opportunities overseas, especially in countries with active mining, oil and gas, and infrastructure sectors. While the Philippine license demonstrates your professional qualification, some countries may require additional licensing, certifications, or recognition of foreign credentials. It is important to research the specific requirements of your target country and prepare documentation of your education, licensure, and work experience.
