What is the Salesforce Certified Platform Developer II Exam?
The Salesforce Certified Platform Developer II certification is designed for IT professionals and seasoned developers who possess a deep understanding of the advanced programmatic capabilities of the Lightning Platform. It validates an individual's expertise in data modeling, building complex business logic, and crafting sophisticated user interfaces using Salesforce technologies. Candidates are expected to demonstrate their ability to design, develop, test, and deploy maintainable, reusable, and object-oriented programmatic solutions that adhere to best practices.
Achieving the PDII certification signifies mastery in several critical areas, moving beyond the foundational knowledge of Platform Developer I. It proves a developer's capacity to handle intricate scenarios, optimize performance, and implement robust, scalable solutions on the Salesforce platform. This credential is a testament to an architecturally minded approach to development, focusing on efficiency, security, and long-term maintainability.
About the Salesforce Certified Platform Developer II Certification Process
The Salesforce Platform Developer II certification is unique in that it's a two-part process, requiring both a comprehensive exam and the completion of specific Trailhead Superbadges. Unlike many other certifications that are solely exam-based, PDII combines theoretical knowledge validation with practical skill demonstration through real-world scenarios on Trailhead.
To earn this highly respected credential, candidates must first hold the Salesforce Certified Platform Developer I credential. Following that, the process involves:
- Passing the Salesforce Platform Developer II Certification Exam: This proctored exam assesses your theoretical knowledge and understanding of advanced concepts.
- Earning Three Specific Trailhead Superbadges: These hands-on challenges demonstrate your practical application of advanced development skills.
The superbadges required are:
- Apex Specialist: Demonstrates mastery of Apex programming best practices, including triggers, Visualforce controllers, batch Apex, and test methods.
- Data Integration Specialist: Focuses on integrating Salesforce with external systems using various API methods, including SOAP, REST, and Apex callouts.
- Advanced Apex Specialist: Challenges candidates with complex Apex scenarios, including asynchronous processing, error handling, and governor limit management.
You can complete the exam and the Superbadges in any order you prefer. The Salesforce Certified Platform Developer II certification is automatically awarded once both components are successfully completed.
Typical Exam Details for Salesforce Certified Platform Developer II
While specific exam details can evolve, the Salesforce Certified Platform Developer II exam typically follows a standardized structure to assess a candidate's advanced development knowledge. Here's a general overview based on historical and common Salesforce exam characteristics:
- Exam Questions: Approximately 60 multiple-choice/multiple-select questions, which may include up to 5 non-scored questions used for statistical analysis.
- Exam Duration: Candidates are usually allotted 120 minutes to complete the exam.
- Passing Score: A passing score of around 70% is generally required.
- Exam Fee: A standard fee (historically around USD 200) applies, with retake fees also typically incurred for subsequent attempts.
It's important to always check the official Salesforce Trailhead website for the most current information regarding exam registration, pricing, and policies before scheduling your exam.
Prerequisites for Salesforce Certified Platform Developer II
Before embarking on the PDII journey, candidates must meet specific prerequisites to ensure they have the foundational knowledge required for advanced topics. The primary prerequisites include:
- Salesforce Certified Platform Developer I Credential: This is a mandatory prerequisite, validating your basic skills and knowledge in developing custom applications on the Lightning Platform. It confirms your proficiency in declarative automation, basic Apex, Visualforce, and data modeling.
- Practical Experience: While not a formal certification, significant hands-on experience is crucial. Candidates should have spent considerable time developing, deploying, and maintaining solutions on the Lightning Platform. This practical application of skills is what the Superbadges are designed to test.
- Completion of Required Trailhead Superbadges: As mentioned, the three specific superbadges (Apex Specialist, Data Integration Specialist, and Advanced Apex Specialist) are an integral part of the certification process, not just preparatory material. Each superbadge provides a practical, scenario-based challenge that solidifies your advanced development skills.
