Scrum Master Certification Guide 2026: CSM vs. PSM and How to Get Certified

Scrum Framework Overview

Scrum is a lightweight agile framework for developing and delivering products and services iteratively. Originally developed for software development in the 1990s, Scrum is now widely applied across product development, marketing, healthcare, and other industries. Scrum organizes work into fixed-length iterations called Sprints (typically 1 to 4 weeks) and emphasizes transparency, inspection, and adaptation throughout the development process.

Scrum Accountabilities (Roles)

Scrum defines three accountabilities within the Scrum Team: Product Owner: responsible for maximizing the value of the product by managing the Product Backlog — a prioritized list of work items. The Product Owner makes decisions about what the team builds and in what order, represents stakeholder interests, and ensures the team is working on the highest-value items. Scrum Master: responsible for the effectiveness of the Scrum Team. The Scrum Master is a servant-leader who coaches the team on Scrum theory and practices, removes impediments, facilitates Scrum events, and helps the organization understand and adopt Scrum. The Scrum Master does not manage the team — they enable the team to manage itself. Developers: the professionals who create the product Increment each Sprint. The Developers are self-organizing and cross-functional — they collectively have all the skills needed to create a potentially shippable product Increment each Sprint without depending on others outside the team. In the current Scrum Guide (2020), all members who work on the Sprint (other than the Product Owner and Scrum Master) are called Developers regardless of their specific discipline.

Scrum Events

Scrum defines five events: Sprint (the container for all other events) — a fixed-length iteration of 1 to 4 weeks during which the team creates a potentially shippable Increment; Sprint Planning — at the start of each Sprint, the team plans what work will be done and how; Daily Scrum — a 15-minute daily event for the Developers to inspect progress toward the Sprint Goal and adapt the Sprint Backlog; Sprint Review — at the end of the Sprint, the Scrum Team and stakeholders inspect the Increment and adapt the Product Backlog if needed; Sprint Retrospective — the Scrum Team inspects itself (processes, tools, relationships) and creates a plan for improvements.

Scrum Artifacts

Scrum has three artifacts: Product Backlog — an ordered list of everything needed to improve the product, maintained by the Product Owner; Sprint Backlog — the Sprint Goal, selected Product Backlog items for the Sprint, and a plan for delivering the Increment; Increment — the sum of all completed Product Backlog items during the Sprint and the value of all previous Increments, meeting the Definition of Done. Each artifact has a commitment: the Product Backlog's commitment is the Product Goal; the Sprint Backlog's commitment is the Sprint Goal; the Increment's commitment is the Definition of Done.

Scrum Certifications Compared

Several organizations offer Scrum certifications. The two primary credentials for Scrum Masters are the CSM (Certified ScrumMaster, from Scrum Alliance) and PSM I (Professional Scrum Master I, from Scrum.org). Understanding the differences helps candidates choose the right certification for their situation.

CSM vs. PSM I: Key Differences

Certified ScrumMaster (CSM) — Scrum Alliance: Requires attending a 2-day in-person or live virtual Certified Scrum Trainer (CST)-led course before taking the exam. The course is mandatory — you cannot take the CSM exam without first completing the course. CSM exam: 50 multiple-choice questions, 60 minutes, 74% passing score. The course cost includes the exam fee — typical total cost $1,000 to $1,500. CSM certification requires renewal every 2 years (Scrum Education Units required). The course requirement means CSM candidates receive structured instruction and networking before certification. Professional Scrum Master I (PSM I) — Scrum.org: No training course required — candidates can register and take the PSM I exam directly without attending a course. Scrum.org provides free online study resources. PSM I exam: 80 multiple-choice questions, 60 minutes, 85% passing score (higher bar than CSM). Exam fee: $200. No renewal required — PSM I is a lifetime certification. PSM I has a higher exam bar and no training requirement, while CSM requires training but has an easier exam. Both are widely recognized by employers. PSM I is generally considered the more rigorous of the two.

Other Scrum Certifications

Beyond CSM and PSM I, candidates may pursue: CSP-SM (Certified Scrum Professional — ScrumMaster, Scrum Alliance) — advanced Scrum Master credential for experienced practitioners; PSM II and PSM III (Scrum.org) — advanced levels of PSM for experienced Scrum Masters; PSPO (Professional Scrum Product Owner, Scrum.org) and CSPO (Certified Scrum Product Owner, Scrum Alliance) — Product Owner credentials; SAFe Scrum Master — for organizations using the Scaled Agile Framework (SAFe), which extends Scrum to enterprise scale; PMI-ACP (Agile Certified Practitioner, PMI) — broader agile practitioner credential covering multiple agile frameworks including Scrum.

CSM Certification Guide

The Certified ScrumMaster (CSM) from Scrum Alliance is one of the most recognized Scrum credentials globally and is the most widely held Scrum Master certification. The mandatory course requirement makes CSM accessible to candidates with no prior Scrum experience.

CSM Course

The CSM course is a 2-day (16-hour) course led by a Certified Scrum Trainer (CST) — a practitioner certified by Scrum Alliance to teach CSM. Courses are available in in-person format at training facilities and as live virtual classrooms (Zoom-based, still instructor-led and interactive). The course covers the Scrum framework in depth: Scrum theory and values, events, artifacts, and accountabilities; the Scrum Master role and servant leadership; practical application through exercises and simulations; and Q&A with an experienced Scrum practitioner. Course cost varies by provider and format — $495 to $1,495 is typical, with the exam fee included in most course registrations.

CSM Exam

After completing the course, Scrum Alliance grants you access to the CSM exam. The exam: 50 multiple-choice questions; 60-minute time limit; 74% passing score (37 of 50 correct); no cost beyond the included first attempt (a fee applies for retakes). The exam is administered online through Scrum Alliance's website. Content covers the full Scrum framework as taught in the course — events, artifacts, accountabilities, Scrum values, and Scrum Master responsibilities. Most candidates who attended the course attentively and review the Scrum Guide before the exam pass on the first attempt.

CSM Renewal

CSM certification is valid for 2 years. Renewal requires earning 20 Scrum Education Units (SEUs) — continuing education in agile and Scrum through workshops, webinars, courses, coaching, and other qualifying activities — and paying the renewal fee (approximately $100). SEUs can be earned from a wide variety of agile learning activities. The renewal requirement keeps the credential current and motivated holders to continue developing their agile skills.

PSM I Certification Guide

The Professional Scrum Master I (PSM I) from Scrum.org is a globally recognized Scrum Master credential with a higher bar than the CSM — an 85% passing score on an 80-question exam with no mandatory training requirement. PSM I is often preferred by experienced practitioners and organizations that value the more rigorous credential.

PSM I Study Resources

Scrum.org provides free, high-quality PSM I preparation resources: The Scrum Guide — the authoritative document defining the Scrum framework (available at scrumguides.org). Reading the Scrum Guide multiple times and understanding every sentence is the foundation of PSM I preparation. Scrum.org Open Assessments — free online assessments (Scrum Open, Product Owner Open, Developer Open) that simulate the question style of the actual PSM I exam. Taking the Scrum Open assessment repeatedly until you consistently score 100% is a strong readiness indicator. Nexus Guide — the guide to Scaled Scrum (while optional for PSM I, familiarity helps with harder questions). PSM I-focused training courses (not required but available from Scrum.org Professional Trainers) provide structured learning for candidates who want guided preparation.

PSM I Exam

The PSM I exam: 80 multiple-choice questions; 60-minute time limit; 85% passing score (68 of 80 correct); $200 fee per attempt. The exam is taken online through Scrum.org — candidates register, pay, and take the exam independently without attending a course. Unlike the CSM, there are no first-attempt-included exam fees in a course; each attempt costs $200. The higher passing threshold (85% vs. CSM's 74%) means candidates must have thorough understanding of the Scrum Guide — surface-level familiarity is not sufficient. Questions on PSM I test nuanced understanding of Scrum theory, the rationale behind Scrum rules, and how to apply Scrum in complex situations.

Scrum Certification Career Value

Scrum master certifications have become standard credentials for agile practitioners — appearing in job postings for Scrum Masters, Agile Coaches, Project Managers, and Product Owners across technology, financial services, healthcare, retail, and government sectors.

Scrum Master Salary

Certified Scrum Masters in the United States earn median salaries of approximately $100,000 to $130,000, with experienced practitioners and those in enterprise environments earning $140,000 to $170,000 or more. Scrum Master positions are concentrated in technology companies, financial institutions, and large enterprises that have adopted agile at scale. Entry-level Scrum Master positions (with CSM or PSM I and 1 to 2 years of experience) typically start at $80,000 to $100,000. The Scrum Master role is a career rather than a stepping stone — experienced Scrum Masters advance to Agile Coach, Release Train Engineer (in SAFe environments), or Portfolio Manager roles.

Which Certification to Pursue First

For candidates new to Scrum: CSM is the more accessible starting point due to the mandatory course — the 2-day training provides foundational knowledge and is appropriate for those who benefit from instructor-led learning. For candidates with technical or project management backgrounds who prefer self-study: PSM I is appropriate — the Scrum Guide provides all needed content; the higher exam bar rewards thorough study. For career advancement in enterprise agile environments: both credentials are recognized; additional credentials (PSM II, SAFe SM, PMI-ACP) add differentiation. Many practitioners hold both CSM and PSM I — the combination demonstrates commitment and multi-perspective understanding of Scrum.
