A scrum master search works when the string writes the title both ways ("scrum master", as the Scrum Guide does, and "ScrumMaster", as Scrum Alliance's CSM does), adds the neighboring titles that do the same job (agile delivery lead, iteration manager, team coach, release train engineer) and then requires practice words a certificate cannot supply: retrospectives, impediments, flow metrics. A CSM comes from a course and a test, and a PSM from a test that needs no class, so the credential alone does not narrow much.
Below are ten strings by kind of agile role, the credentials behind the terms, and what LinkedIn, Indeed and Google support as of November 2026. For the operators themselves, see Boolean search strings for recruiters; for the first call, see the scrum master screening questions.
Credentials and titles that change what a scrum master search finds
| Credential | Issued by | What it involves, per the issuer |
|---|---|---|
| CSM, Certified ScrumMaster | Scrum Alliance | 16 hours of training, then a 50-question test with 37 correct to pass |
| A-CSM and CSP-SM | Scrum Alliance | Advanced Certified ScrumMaster and Certified Scrum Professional ScrumMaster |
| PSM I, II and III | Scrum.org | Fundamental, advanced and distinguished levels; tests open with or without a class |
| SSM, SASM, RTE | Scaled Agile | SAFe Scrum Master, SAFe Advanced Scrum Master, SAFe Release Train Engineer |
| PMI-ACP | PMI | An experience-based agile certification; PMI lists 2+ years of experience |
| ICP-ATF | ICAgile | Agile Team Facilitation, aimed at scrum masters, agile coaches and team leads |
- Two spellings of one title. The 2020 Scrum Guide says the Scrum Master is accountable for the Scrum Team's effectiveness, and writes it as two words; Scrum Alliance's CSM page writes ScrumMaster as one, as of November 2026. Put both in the title block.
- Scrum Alliance's ladder. Its scrum master track runs from CSM to the Advanced Certified ScrumMaster (A-CSM) and the Certified Scrum Professional ScrumMaster (CSP-SM). The advanced credentials are a better signal of time in the role than the CSM.
- Scrum.org. Its certification page lists PSM I, II and III and a PSM-AI Essentials credential, and says its tests can be taken whether someone has taken a Scrum.org class or not.
- Scaled and experience-based credentials. Scaled Agile's certification page lists SAFe Scrum Master (SSM), SAFe Advanced Scrum Master (SASM) and SAFe Release Train Engineer (RTE). PMI's PMI-ACP page lists 2+ years of experience, and ICAgile describes its Agile Team Facilitation course as designed for scrum masters, agile coaches and team leads.
Ten Boolean strings by kind of agile role
Swap in the tools, industry and setting from your own intake; these are examples. None of them uses graduation years or any other proxy for a protected characteristic, and yours should not either.
Team-level scrum masters
1. Scrum master with practice evidence — LinkedIn general search
("scrum master" OR scrummaster OR "agile scrum master") AND (csm OR psm OR "certified scrummaster" OR "professional scrum master") AND (retrospectives OR "sprint planning" OR impediments) NOT (recruiter OR trainer OR rugby)
2. Practice first, credential optional — LinkedIn Recruiter, Job titles + Keywords filters
("scrum master" OR scrummaster OR "team coach") AND ("facilitated retrospectives" OR "removed impediments" OR "flow metrics" OR "cycle time") NOT ("project coordinator" OR intern)
3. Scrum master on Jira or Azure DevOps — Indeed Smart Sourcing
title: ("scrum master" OR scrummaster OR "agile delivery lead") AND skill: (jira OR "azure devops" OR confluence) NOT ("jira administrator")Scaled agile and coaching
4. SAFe scrum master or release train engineer — LinkedIn general search
("scrum master" OR "release train engineer") AND ("scaled agile" OR "safe scrum master" OR "safe advanced scrum master" OR sasm) AND ("pi planning" OR "program increment" OR "agile release train") NOT recruiter
5. Agile coach — LinkedIn Recruiter, Job titles filter
("agile coach" OR "enterprise agile coach" OR "agile team coach") AND ("icp-acc" OR icagile OR "csp-sm" OR "psm iii" OR "a-csm") NOT ("life coach" OR "career coach" OR "sports coach")
6. Kanban-leaning delivery lead — LinkedIn general search
("delivery lead" OR "agile delivery manager" OR "iteration manager" OR "scrum master") AND (kanban OR "wip limits" OR "flow efficiency" OR "service level expectation") NOT (warehouse OR inventory OR manufacturing)Industry, technical depth and career changers
7. Scrum master in a regulated industry — LinkedIn general search
("scrum master" OR scrummaster) AND (banking OR "financial services" OR healthcare OR "public sector") AND ("pmi-acp" OR psm OR csm) NOT recruiter
8. Technical scrum master — Indeed Smart Sourcing
title: ("scrum master" OR "technical scrum master") AND skill: ("ci/cd" OR devops OR "software development" OR aws) NOT ("scrum master trainer")
9. Project manager moving into scrum — LinkedIn general search
("project manager" OR "program manager") AND ("scrum master" OR csm OR psm OR "pmi-acp") AND ("sprint planning" OR retrospectives OR "daily scrum") NOT (construction OR facilities)Search-engine X-ray
10. Public profiles by credential and city — Google X-ray
site:linkedin.com/in "scrum master" "psm ii" "atlanta" -jobs -recruiter -trainerWhat LinkedIn, Indeed and Google actually support
As of November 2026, LinkedIn's Boolean help page requires AND, OR and NOT in capitals, supports quotes and parentheses, and does not support wildcards, so "scrum master" and "scrummaster" are different terms. LinkedIn Recruiter's Boolean page lists Job titles and Skills and Assessments among its Boolean filters and says the + and - operators are not officially supported; put hyphenated credentials such as "a-csm" and "csp-sm" in quotes so the hyphen is read as part of the term.
Indeed's advanced search
post documents title: for the most recent title and anytitle: for any title held,
and its industry guides document skill:. Use anytitle: to find people who were scrum
masters before a recent promotion to delivery manager.
Google's search operators page documents quotes,
site:, the minus sign and filetype:, but not OR, so string 10 uses one credential at a
time.
Three issuers publish lookups. Scrum.org's certification list lets you search Professional Scrum certification holders and view their certifications. PMI's Certification Registry finds active and retired credential holders, and says holders can opt out. Scaled Agile's support article says it will not disclose certification data, that its directory is opt-in, and that absence from it may not reflect certification status; ask SAFe candidates for their digital badge.
Narrowing by team setup, framework and industry
Team setup comes first. A scrum master for one team, one who supports two or three, and a release train engineer across a dozen are different jobs. Ask the client how many teams and how mature they are, then pick the title block: team-level titles for strings 1 to 3, scaled titles for string 4, coaching titles for string 5.
The framework comes next. A SAFe organization wants PI planning and agile release train language; a Kanban shop wants flow metrics; a team new to Scrum wants someone who has introduced the events, not just run them. One framework block changes the list more than any certificate.
Industry narrows last. Regulated industries often value someone who has worked with audit, change control and release approvals, which string 7 targets. If the client does not care, leave industry out and keep the pool wide.
False positives worth excluding with NOT
- Rugby. Scrum is a rugby term and scrum-half a position. Always search the phrase "scrum master", and add NOT rugby if players and coaches appear.
- Trainers selling the course. Certified Scrum Trainers and training companies list every credential. Exclude "trainer" and "scrum master trainer" for delivery roles.
- Other coaches. Life, career and sports coaches match "coach". Exclude them from agile coach searches, as string 5 does.
- Lean manufacturing and warehouse Kanban. Kanban is also a lean manufacturing method, and warehouse and manufacturing profiles use the word daily. Exclude warehouse, inventory and manufacturing from software delivery searches.
- Recruiters, coordinators and Jira admins. Agile recruiters list every title; project coordinators and Jira administrators share the tools. Exclude them by title.
A worked example: three passes on a SAFe search
An invented search, shown as it actually gets narrowed.
Intake: A bank needs a scrum master for two teams on a payments release train, with PI planning experience, on site three days a week.
Pass 1: "scrum master" AND safe: every scrum master who mentions a safe
environment, safety-critical software or psychological safety, plus SAFe trainers.
Pass 2: ("scrum master" OR scrummaster) AND ("scaled agile" OR "safe scrum master" OR
sasm) AND ("pi planning" OR "agile release train") NOT (trainer OR recruiter): relevant, though it mixes
every industry.
Pass 3: add AND (banking OR payments OR "financial services"). The list is short
enough to call, and the screen asks for the last impediment they escalated beyond the train.
The plain word "safe" was the trap; the framework phrases did the narrowing, and the industry block did the rest.
What a search cannot verify
A string can find someone whose profile shows the right title, framework and credential. It cannot show whether they changed how a team works, handled a difficult product owner or held a retrospective people found useful. The scrum master screening questions test that practice, the project manager phone screen questions help when a client is open to career changers, the 30-60-90 day plan for scrum masters covers the first quarter after the hire, and the project manager strings and product manager strings cover the neighboring roles.
Questions people ask
Should I search scrum master or ScrumMaster?
Both. The 2020 Scrum Guide writes Scrum Master as two words, while Scrum Alliance's credential is the Certified ScrumMaster, one word. LinkedIn does not support wildcards, so a string with only one spelling misses the profiles that copied the other.
Does a CSM or PSM prove someone has run a scrum team?
No. Scrum Alliance's CSM page describes 16 hours of training and a 50-question test needing 37 correct answers, and Scrum.org says its tests can be taken whether or not someone attended a class. Both show knowledge of the framework; practice words such as retrospectives, impediments and flow metrics, and the screen, show whether they used it.
How do I verify a PSM, PMI-ACP or SAFe certification?
Scrum.org publishes a certification holder search, and PMI's Certification Registry finds active and retired credential holders, though PMI says holders can opt out. Scaled Agile says it will not disclose certification data and that absence from its opt-in directory may not reflect status, so ask SAFe candidates for their digital badge.
Why do rugby players show up in a scrum master search?
Because scrum is a rugby term and scrum-half is a position, so a bare scrum search pulls in players and coaches. Use the phrase "scrum master" rather than scrum on its own, and add NOT rugby if they still appear.
