With the change of the CSP blueprint from version 10 (CSP10) to the new version 11 (CSP11) starting August 2025, it has become essential for every professional seeking the Certified Safety Professional certification to understand the key differences and update their study plan. In this article, we highlight the main changes to the domains, content distribution, and the weight of each topic in the exam, linking them to our preparation course, carefully designed to align with the new update.
First, what is a blueprint in professional certification exams?
The blueprint is simply the official map of the exam content. It is prepared by the certifying body, such as the Board of Certified Safety Professionals (BCSP), and is used to define the topics that the candidate should be familiar with, as well as the weight of each topic in the exam content and the level of knowledge required for each topic.
Updating the blueprint does not only mean changing the order of topics; it also reflects the evolution of the profession and market requirements, aiming to ensure that the certificate holder truly possesses the competence to work in the field.
Why was the update made from CSP10 to CSP11?
Periodically (approximately every five years), the Board of Certified Safety Professionals (BCSP) reviews and approves the CSP exam content to ensure it aligns with the latest professional standards in safety, health, and environment. The re-evaluation process began in 2024, leading to the release of the new CSP11 blueprint, which was officially implemented on August 1, 2025.
The key changes in the CSP11 Blueprint
Despite updates to the organization of the knowledge domains and the distribution of content, the vast majority of concepts present in the previous CSP10 blueprint remain in the new CSP11 blueprint.
In other words, the change was not radical; it can be described as a reorganization and enhancement in how the required skills are presented, with greater emphasis on skill-based statements and clarifying the level of knowledge required for each topic.
Below is a summary of these changes.
1. Science and Math
Previously, the principles of mathematics and science were concentrated in Domain 1 of CSP10. Now, in CSP11, they have been distributed across several domains, with basic arithmetic concepts—which are sufficiently covered in the ASP certification—removed, and the focus shifted instead to practical calculations related to safety.
2. Content Consolidation and Reorganization of Domains
| CSP10 Domain Name | Change in CSP11 |
|---|---|
| Domain 4: Advanced Application of Key Safety Concepts | Merged with Domain 1 and Domain 2 in CSP11 |
| Domain 5: Emergency Preparedness, Fire Prevention, and Security | Became Domain 4 titled Emergency Management, retaining fire prevention and security concepts |
| Domain 6: Occupational Health and Ergonomics | Became Occupational Health and Applied Science, integrating chemistry and physics concepts |
| Domain 7: Environmental Management Systems | Became Environmental Management, with REACH and RoHS removed and new concepts on environmental impact added |
| Domain 8: Training/Education | Became Domain 7 titled Training, with focus on the continuous improvement model and adult learning principles |
| Domain 9: Law and Ethics | This domain has been removed in CSP11 |
3. Changes in the Percentage Weight of Each Domain
Some domains experienced a slight decrease in relative weight in the new CSP11 blueprint, such as:
Risk Management
Emergency Management
Environmental Management
Occupational Health and Applied Science
Training
While there was a noticeable increase in focus on:
Advanced Application of Safety Principles
Program Management
These two domains now together represent 50% of the entire exam content, reflecting the shift toward assessing the applied and managerial skills of safety professionals.

Frequently Asked Questions Regarding This Update
No, the changes are not radical. Most of the core concepts you prepared for in CSP10 are still present in CSP11. Some topics have been redistributed, and the contents of certain domains have been merged, but the main topics remain the same. The only notable change is the increased focus on the ‘Advanced Application of Safety Principles’ and ‘Program Management’ domains, which now make up half of the exam content.
No need to worry, because the materials you are already studying cover most of the topics required in CSP11. We just recommend dedicating extra time and review to the ‘Advanced Application of Safety Principles’ and ‘Program Management’ domains, as they now carry more weight.
Yes, absolutely. As mentioned earlier, there are no entirely new topics—only changes in order and emphasis. All core topics are fully covered in our preparation course, with special focus on the domains that have increased in weight, such as ‘Advanced Application of Safety Principles’ and ‘Program Management,’ to ensure comprehensive and effective readiness.
There are no entirely new topics; most of the core topics remain the same.
