The Pre-Delegation Testing (PDT) process allows ICANN to determine if registries meet specific “technical and operational requirements” deemed necessary to maintain a new gTLD. ICANN staff has estimated that the average length of PDT from starting PDT to receiving results has been 3-4 weeks, as opposed to the previously suggested 6 weeks. PDT includes testing registry system operations and DNS server operational infrastructure.  Resources, from self-testing tools to PDT FAQs can be found on ICANN's Pre-Delegation Testing Page.
- The PDT process is being changed and updated currently regarding data escrow requirements.
ICANN identified key elements in PDT as:
- Agreeing upon a test appointment date with ICANN through the Customer Service Portal
- Beginning data entry after receiving notification and completing all entries before the test appointment
- PDT service providers conduct the testing.
- Registries are given their test results through the Customer Service Portal.
