LEA Exam Coverage 2026: Agriculturist Board Exam Subjects, Passing Rate and Qualifications
Updated:
The Agriculturists Licensure Examination, commonly called the LEA or Agriculturist Board Exam, measures an examinee’s knowledge of crop production, animal production, soil management, crop protection, agricultural business and agricultural extension.
This guide presents the six principal LEA subjects, topics to prioritize during review, the current statutory passing requirement, applicant qualifications and practical preparation strategies.
LEA Exam Coverage
The written professional examination for registered agriculturists covers six foundation subjects:
| Subject | Main Area of Study |

To pass the Agriculturists Licensure Examination, an examinee must:
- Obtain an average rating of at least 75 percent across all examination subjects; and
- Have no rating below 50 percent in any subject.
These provisions replace the older information on this page stating that the required average was 70 percent and the minimum subject rating was 60 percent.
Qualifications for the Agriculturists Licensure Examination
At the time of filing the application, an applicant must generally meet the following qualifications:
- Be a citizen of the Philippines or a citizen of a foreign country that grants reciprocity for the practice of the agriculture profession;
- Hold a Bachelor’s Degree in Agriculture or an agriculture-related degree from a government-recognized school, college or university;
- Have completed the prescribed agricultural coursework, including the six foundation subjects;
- Complete the minimum number of agricultural units prescribed by the Professional Regulatory Board;
- Be of good moral character; and
- Have no conviction for a crime involving moral turpitude.
Government agriculture personnel
Certain incumbent personnel holding agriculture positions in national, regional or local government offices, agencies or government-owned or controlled corporations may also qualify, subject to the conditions prescribed by law and the Professional Regulatory Board.
Such applicants may be required to possess professional civil service eligibility and to have completed the prescribed agricultural coursework and minimum units.
General LEA Application Requirements

How to Review for the LEA
1. Start with a diagnostic test
Answer a set of questions from all six subjects before creating your study schedule. Use the results to identify the areas that require the most attention.
2. Divide review time among all six subjects
Do not review only the subjects related to your college specialization. The examination covers the entire agriculture foundation, including technical, economic and extension subjects.
3. Understand concepts instead of memorizing lists
Many examination questions require the application of agricultural principles to a farm, business or community situation. Understand why a management practice is appropriate rather than memorizing its name alone.
4. Practice computations regularly
Include exercises involving fertilizer rates, feed formulation, farm budgeting, production costs, economic analysis, percentages, ratios and other quantitative applications.
5. Review Philippine agricultural conditions
Relate scientific principles to Philippine crops, livestock systems, climate, soils, agricultural policies, markets and rural communities.
6. Review incorrect answers
Keep a record of mistakes and classify them by subject. Determine whether each error resulted from weak content knowledge, a misunderstood question or a computation mistake.
7. Take timed practice examinations
Timed tests help improve concentration, pacing and decision-making. Practice moving past a difficult item and returning to it after completing easier questions.
