Individuals at this level have a basic understanding of Terraform's purpose and can perform simple tasks like installation and executing basic commands. They are familiar with the documentation and can create simple configuration files, but require guidance for more complex tasks.

Novices can define variables, manage state files, and use providers to interact with cloud services. They can write basic modules and understand resource dependencies, but still rely on structured guidance and support for troubleshooting and advanced configurations.

Intermediate users can manage remote states, use data sources, and create reusable modules. They are capable of implementing conditionals and loops, and can troubleshoot common errors independently. They begin to optimize configurations and integrate Terraform into CI/CD pipelines.

Advanced practitioners design complex infrastructure solutions and ensure compliance and security in their Terraform code. They integrate Terraform with CI/CD pipelines and implement policy as code. They focus on performance optimization and can handle large-scale deployments with minimal supervision.

Experts architect large-scale, multi-cloud solutions and contribute to Terraform open-source projects. They develop organizational standards, lead training sessions, and evaluate new technologies. Their deep expertise allows them to innovate and drive strategic initiatives within their organizations.
