Earning the Looker Certified Explorer credential requires four things: a Google account, a Webassessor registration, enough Looker and LookML knowledge to pass a ~50-question multiple-choice exam, and $200 USD for the exam fee. The process is straightforward, but candidates who skip preparation for the LookML portions consistently struggle.
What Is the Certification Path for Looker Certified Explorer?
Step 1: Create or Confirm Your Google Account
All Google Cloud certifications are tied to a Google account. You need a personal or professional Google account to register on Webassessor. If your company uses Google Workspace, you can use your work email, but personal Google accounts also work. There are no prerequisites for the Looker Certified Explorer exam — Google does not require prior certification or minimum years of experience to register.

Step 2: Register on Webassessor
Google delivers its certification exams through Webassessor (kryterion.com). Create an account at webassessor.com using your Google email, search for "Looker Certified Explorer," and select the exam. You can schedule for any available date and time — the exam is online and proctored, so you take it from your own computer. You will need a valid webcam, a quiet room, and a government-issued photo ID. The exam fee is approximately $200 USD. Verify the current price at cloud.google.com/certification before registering.
Step 3: Prepare — Specifically for the LookML Portions
Google provides an official exam guide at cloud.google.com/certification/looker-explorer. Read it before you start studying to understand which domains are covered. The most frequently underestimated portion is LookML: view files, model files, Explore definitions, dimensions vs measures, derived tables, and the dev mode vs production mode workflow. If you have only used Looker as an end user and have never opened a .lkml file, plan at least 3–4 weeks specifically on LookML concepts.
Useful preparation resources include the Looker developer documentation at developers.looker.com, Google Cloud Skills Boost (the official training platform), and hands-on practice in a Looker instance if your employer gives you access. The Looker Cert Prep PDF guide covers every exam domain with worked LookML examples, a domain-by-domain checklist, and 50 practice questions.
Step 4: Take the Exam
The exam is approximately 50 multiple-choice and multiple-select questions delivered online with webcam proctoring. You have 120 minutes. You cannot use documentation, notes, or any external resources during the exam — it is closed-book. Questions are scenario-based, meaning many questions give you a situation (a data analyst needs to do X in Looker) and ask you to identify the correct LookML approach or platform feature. Pure definitional questions ("what is a measure?") exist but are not the majority.
Step 5: Receive Your Credential and Add It to Your Profile
Google sends exam results within a few minutes of submission for most candidates. If you pass, your credential appears in your Webassessor account and in Google's credential verification system. Looker Certified Explorer credentials are valid for 2 years — Google sends renewal reminders before expiry. Add the credential to LinkedIn using the "Add credential" feature on your profile and reference it on your resume under certifications.
