Pega Certified Lead System Architect

Lead System Architects are responsible for the design and quality of Pega solutions.

Your PCLSA journey begins here

Pega Lead System Architects lead implementation teams and ensure that solutions leverage the technology to provide optimum business value. They provide technical mentoring and leadership across teams.


    You can accelerate your PCLSA certification time!

The PCLSA Learning Path Overview

This learning path combines Pega Academy courses with on-the-job experience to ensure that system architects get exposure to the breadth and depth of Pega products which is required to perform effectively in a leading role.

PCLSA Prerequisites

PCLSA is the highest level of technical achievement in Pega. Prior to training as a Lead System Architect, individuals must gain field experience and demonstrate their technical aptitude by earning first their System Architect and then their Senior System Architect certifications. 

Build Expertise

Pega recommends that real-world experience of at least 12 months be gained before attempting to achieve the PCLSA certification. Working twelve months or longer implementing Pega applications expands the depth of Pega knowledge and builds the expertise that is required to successfully complete the program.

However, recognizing that each person has different project implementation opportunities, Pega Academy is introducing a self-paced course that helps senior system architects fill potential gaps in knowledge and experience. The Senior System Architect Advanced Topic course is based on the Pega 8.3 Platform. 

  • Please note the Senior System Architect Advanced Topics course is only available in the previous version of Pega Academy.

Senior System Architect Advanced Topics include:

  • Customizing Security Requirements in Pega Applications
  • Configuring Agent Processing 
  • Customizing the User Experience 
  • Improving Application Performance 
  • Creating Mobile Solutions 

LSA Readiness Assessment

When senior system architects are confident that they can configure a Pega solution to successfully meet most business requirements, they can take the LSA Readiness Assessment.  

The LSA Readiness Assessment is an assessment that is taken within the Pega Academy website. This assessment checks knowledge on more advanced configuration topics such as Mobility, Performance, and Authentication. A passing score validates that senior system architects are ready to move to the next level of Pega mastery – design and architecture.

The LSA Readiness Assessment mission is completed in the Pega Academy web site.

Lead System Architect

Senior system architects who pass the LSA Readiness Assessment can register for the Lead System Architect course.  The two week course teaches best practices in technical design and architecture of a Pega application. System architects use their configuration skills to build an application that they design and architect.  

Topics include:

  • Enterprise Design
  • Case Design
  • Data Model Design
  • User Experience Design
  • Security
  • Reporting
  • Asset Design and Reuse
  • Background processing
  • Performance
  • Deployment and Testing

Testing Requirements

To complete the PCLSA certification, system architects must take and pass two exams in the following order:

  • Pega Architecture Exam 
  • LSA Architecture Application Build


Pega Architecture Exam

The Pega Architecture exam validates that system architects have mastered the design and architecture skills taught in the Lead System Architect course and that they can guide an application development team on configuration decisions. 

The Pega Architecture exam is a two hour standard exam that is delivered at Pearson VUE testing centers. The exam blueprint, which includes prerequisites and exam topics, is available here in Pega Academy. Additional exam information and registration is available at the Pearson VUE site.

LSA Application Build

The LSA App Build tests one’s ability to architect, implement and analyze Pega Platform solutions. Working within a set of business requirements, system architects will be required to:

  • Design and implement extensible and reusable solutions for new requirements
  • Analyze key areas of the current design and identify architectural deficiencies
  • Identify problem areas and propose solutions for existing applications
  • Document your analysis and solutions using a supplied documentation template

Now comprised of two individual phases, candidates will be responsible for designing a solution to business scenarios in Phase I. Candidates will then implement a solution based on their proposed design for one of these scenarios in Phase II.

The Application Design phase of the exam is completed over a 7 day period, and requires a score of 75% in order to pass. This portion of the exam will require candidates to review business scenarios and determine optimal designs for various aspects of each solution by documenting their design thought process.

Next, the Application Build phase is also completed over a 7 day period. The App Build requires a score of 75% in order to pass. This portion of the exam will require candidates to fully implement a Pega application based on the optimal designs proposed for one of the business scenarios in the App Design phase.

Both phases of the exam require approximately 30 hours effort to complete. This 30-hour allocation should give a candidate time to complete the exam with minimal disruption to their normal work schedule.

The LSA Application Build is managed by Pega. Please contact the CLSA Team at to register for the Application Build. 

You can prepare for the CLSA Application Build with the CLSA App Build Exam Prep Clinic, available for free on Pega Academy.

Visit the Pega Collaboration Center to find App Build exam samples and receive test taking advice from instructors.
