Credential Engine has uploaded 14 STEM Advanced Placement (AP®) assessments and courses to the Credential Registry — a cloud-based library that collects, maintains, and connects information on all types of credentials. Each course and assessment entry includes information about the course, exam, and relevant skills. Adding AP coursework and exams to the Credential Registry allows everyone to consistently access, reference, and align key information across providers. 

For example, information about the AP Computer Science Principles coursework, exam, and skills can now be accessed using the Credential Registry, the Credential Transparency Description Language (CTDL) schema, and linked open data applications. The CTDL is the standard common language for credentials so people can easily understand what a credential means, which specific skills and competencies are associated with it, where credentials can be attained, and what outcomes they lead to. Credential information that is in CTDL and uploaded to the Registry can be integrated with student-facing applications for viewing, such as the Credential Finder, so people can easily find and compare their options.

Multiple stakeholders will benefit from having AP assessment and course information in the Registry. For example: 

  • High school students and counselors can now access key information about specific AP coursework and exams using any product that integrates with the Credential Registry. 
  • Postsecondary administrators can now articulate credential connections with AP coursework and exams, such as advanced standing or specific amounts of transfer value.
  • State education officials can now integrate AP coursework and exams into their career pathways via connections with credentials, courses, competencies, occupations, and jobs. 

The Advanced Placement Program offers college-level courses and exams that students can take in high school, giving them the opportunity to challenge themselves, explore their interests, earn college credit and placement. This means students can save time, money, and get a head start on their education when they enter college with credit they have earned through AP.  If you have questions about the Advanced Placement Program or want to learn more, please visit the AP Central webpage.
