Question 8

What is the passing score for the Terraform Professional exam?

Accepted Answer

HashiCorp does not publicly disclose the exact passing score for the Terraform Authoring and Operations Professional exam. Grading is based on validation of your configuration syntax, Terraform state files, and the actual settings on the provisioned infrastructure resources. Each lab is scored independently.

Question 9

Do I need the Terraform Associate certification before taking the Professional exam?

Accepted Answer

While the Terraform Associate certification is not a hard prerequisite, HashiCorp strongly recommends holding it or having equivalent knowledge before attempting the Professional exam. The TAO-Pro is designed for practitioners with extensive production experience in both authoring and operations. Training without deep hands-on experience is not sufficient preparation.

During the exam you have access to Terraform documentation, AWS provider documentation on the Terraform Registry, limited Terraform Registry access, limited AWS documentation, and the AWS console.

Question 11

Which cloud provider is used in the Terraform Professional exam?

Accepted Answer

The current version of the TAO-Pro exam uses the AWS provider exclusively. Candidates must have extensive production experience using Terraform with AWS. HashiCorp is developing an Azure edition of the exam, which is expected to release in the second half of 2026.

Question 12

How long is the Terraform Professional certification valid, and how do I renew it?

Accepted Answer

The Terraform Authoring and Operations Professional certification is valid for 2 years.

If your certification has already expired, you can retake the exam at any time to receive a new set of credentials with a new expiration date.

Question 13

What Linux skills do I need for the TAO-Pro exam?
