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.

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

After earning Pega Certified Senior System Architect (PCSSA) certification, 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 recommends that PCLSA candidates at a minimum become familiar with the features and functions of the latest Pega version prior to starting the PCLSA program. The Senior System Architect mission will help you learn about the latest features and functions.

12+ months experience

Senior System Architect topics include:

  • Customizing Security Requirements in Pega Applications
  • Configuring Background Processing 
  • Customizing the User Experience 
  • Improving Application Performance 
  • Creating Mobile Solutions
  • ...and much more! 

Lead System Architect Course

Senior system architects who pass the LSA Readiness Assessment can take the Lead System Architect mission or register for the Lead System Architect Instructor-Led 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:

  • Pega Platform Design
  • Application Design
  • Data Model Design
  • User Experience Design
  • Security Design
  • Reporting Design
  • Asynchronous Processing Design
  • Work Delegation Design
  • Deployment and Testing Design
application design and build phase

Testing Requirements

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

  • Pega Architecture Exam 
  • LSA Architecture Design/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 cost is $175 per exam attempt. 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. PCLSA candidates only need to pass the Architecture exam once in any version to be eligible for the LSA App Build.

You can prepare for the Pega Architecture exam by taking the PCLSA Architecture Exam Preparation Clinic, available for free. View the schedule in Pega Academy.

PCLSA Application Design and Build

After successfully completing the LSA Architecture exam (in any version), the final step is the PCLSA Application Design & Build. The PCLSA App Design/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:

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

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. Candidates who live in non-native English speaking countries will be allowed 14 days for the Application Design phase of the exam. (View our Pega Academy FAQ for information on which countries are included to receive additional time.)

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.

Each phase of the exam requires approximately 35 hours to complete (depending on experience)This time allocation should give a candidate time to complete the exam with minimal disruption to their normal work schedule.

The PCLSA Application design/build exam is managed by Pegasystems. The cost is $150 per attempt until November 30th, 2021. (NOTE: The price will increase to $600 per attempt starting December 1st, 2021.) Please contact the CLSA Team at to register for the Application Build. 

You can prepare for the PCLSA Application Build with the PCLSA App Design and Build Preparation Clinic, available for free. View the schedule in Pega Academy.

We take the quality of the CLSA App Build practical exam very seriously. Each version of the exam requires significant development time to create and maintain, as well as the time required to grade each individual exam submission. To ensure we are able to maintain the long-term viability of this exam offering, we are raising the price to $600 on October 1, 2021.

Based on candidate feedback, we have decided to extend the time frame to allow more flexibility. The PCLSA App Build Exam is now broken up into two separate exam parts, with each phase demanding approximately 35 hours of work each.

These two portions are administered across two separate weeks. Candidates will receive one full week (7 days) to complete the App Design and submit for grading. If the App Design is approved, candidates can schedule an additional week (7 days) to build the Application based on their proposed design.

The exam is not completed until the candidates receive a passing score on both the Design and the Build.

We want to make the exam as accessible as possible.  We understand the candidates have project work and deadlines to meet.  By expanding the amount of time allowed, we aim to provide more flexibility to complete the App Design and Build during personal hours instead of requiring dedicated time off the project.

App Design grading is based on the candidate’s ability to identify, evaluate, and document possible Pega solutions to solve selected aspects of a business scenario. The candidate should document his design thought process when comparing possible solutions to arrive at an optimal solution. A common error is to present only a single possible design which does not demonstrate the candidate’s architectural experience in identifying and evaluating solutions.

App Build grading is based on the candidate’s ability to fully implement a Pega application based on the optimal solution reached in their App Design phase. Grading criteria includes (but is not limited to): Functionality and implementation method of the required features, best practices, re-usability, security, user experience. A production ready application is expected. A design document is NOT required since it is based on the design submitted in the previous phase.  The candidate should however, submit a functional test document which guides the grader through testing the various requirements presented in the business scenario.

Yes, if you scored above a 60% on your 8.5 CLSA App Design document, you can amend the documentation and resubmit for consideration at no additional cost. If you score below a 60%, the CLSA Team will provide feedback for your review and you may re-attempt the App Design after 3 months. You will be subject to paying the exam fee at that time, as this will be an entirely new exam to complete.
