Program details

Exam candidate agreement

Please see our terms and privacy policy. You’ll be asked to agree to this before you begin your exam.

Languages available

Our exams are available in English.

Special accommodations

To request an accommodation, please contact us at certification@looker.com before scheduling your exam.

Testing accommodations are considered on a case-by-case basis and may require supporting documentation. Depending on the accommodation requested, it can take 30+ days prior to your test date to arrange the accommodations—so please reach out early.

Retake policy

If you don’t pass an exam, you can retake it after five days. But before you register again, make sure to review the study materials, as you’ll only be allowed three attempts in a 12-month period. Please note that payment is required each time you take an exam.

If you try to get around this policy somehow (including by registering under a different name), your certification will be denied or revoked.

We'd much rather award you a certification than take one away. If you need more than three attempts, please use the rest of that 12-month period to build up your Looker skills using the many resources at your disposal.

Scaled scoring

It’s extremely important to us that you are evaluated fairly when you take a Looker Certification exam. Here are a few ways we ensure that happens:

  • Passing scores are set using statistical analysis, and are subject to change as tests are updated
  • We use scaled scoring models to ensure consistency across multiple exam forms and versions

Because they get updated from time to time, we don’t publish specific passing scores. The important thing is knowing if you passed or not, and we’ll tell you that right away by email.

Receiving a certification / logo

Once you pass a Looker Certification exam, you will immediately receive an email that includes a PDF certificate. Yes, that’s instant bragging rights.


Since the Looker platform is updated regularly, your Looker Certification needs to be updated regularly, too. To keep your certification active each year, you will need to take a recertification exam during the certification maintenance window. Here are the details:

  • Exam type: non-proctored, with multiple choice or multiple response questions
  • Length: 10-20 questions
  • Registration Fee: $20 fee per take
  • Exam duration: 60 minutes
  • Score needed to pass: 80%
  • References: Open book
  • Retakes: Unlimited (see above for cost associated with each retake)
  • Availability: annually, 1st Monday of January through 31st of March (recertification to be taken the calendar year after your pass date)
