+## Certification vs Other Content Types
 
 To better understand its unique role, here is a comparison with other content types in the Academy:
 
 | Feature | Learning Path | Challenge | Certification |
 | :--- | :--- | :--- | :--- |
-| **Primary Goal** | To teach and guide through a comprehensive curriculum. | To solve a specific, hands-on problem in a competitive or timed scenario. | To **validate** and **prove** existing knowledge through formal examination. |
-| **Structure** | Hierarchical (Path → Courses → Modules). | Typically a single, scenario-based task. | Flat; a collection of one or more exams. |
-| **Main Content** | Lessons, informational pages, labs, and progressive assessments (Quizzes/Tests). | A set of instructions for a practical task and a validation mechanism. | A series of rigorous exams, potentially with a brief study guide. |
-| **Outcome** | Acquired knowledge and skills. | A score, rank, or completion status. | An **official certificate** and a badge signifying verified expertise. |

-### Directory Structure

-All content for a new certification must reside within the main `content/certifications/orgID` directory. The structure is organized to group certifications by the organization that provides them, ensuring clarity and scalability.
