The Philippine Criminologist Licensure Examination (CLE) is a rigorous three-day board examination administered by the Professional Regulation Commission (PRC) and the Professional Regulatory Board for Criminology. Success demands a mastery of statutory provisions, criminal procedure, tactical law enforcement operations, forensic sciences, and correctional frameworks. Techsider Solutions publishes this master study guide alongside CLEReady, our offline-first Android and web practice tool.

The 3-day examination structure and area weights
The CLE distributes 100% of the overall rating across six specialized subject areas tested over three consecutive days. Understanding the weight of each area dictates where to allocate your study hours:
| Examination day | Subject area | Board weight | Questions (typical) |
|---|---|---|---|
| Day 1 Morning | Criminal Law and Jurisprudence (CLJ) | 20% | 100 items |
| Day 1 Afternoon | Law Enforcement Administration (LEA) | 15% | 100 items |
| Day 2 Morning | Crime Detection and Investigation (CDI) | 20% | 100 items |
| Day 2 Afternoon | Forensic Science (Criminalistics) | 15% | 100 items |
| Day 3 Morning | Criminology (Theories & Human Behavior) | 20% | 100 items |
| Day 3 Afternoon | Correctional Administration (CA) | 10% | 100 items |
Passing criteria under the Criminology law mandate a general weighted average of at least 75%, with no single area rating below 50%. Triage your study time so high-weight areas (CLJ, CDI, Criminology at 20% each) anchor your average, while technical areas (Forensic Science) do not drop below the 50% threshold.

Exam-day strategy: pacing across a 3-day marathon
- Stamina over speed: The CLE is an endurance test. Tucking in white collars, sitting through long hours, and managing mental fatigue across three consecutive days requires physical preparation and adequate hydration.
- Eliminate distractors first: For legal questions, identify the exact element missing in the scenario. A single missing element (such as absence of intent or absence of force) frequently converts one crime to another.
- Daily diagnostic review: Before each day’s subjects, review concise key points and avoid cramming complex new statutes late at night.
