CLDR training (for new linguists)

Before getting started to contribute data in CLDR, and jumping in to using the Survey Tool, it is important that you understand the CLDR process & take the CLDR training. It takes about 2-3 hours to complete the training.

*If you (individual or your organization) have not established a connection with the CLDR technical committee, start with Survey Tool Accounts.

Critical reminders (for all linguists)

You're already familiar with the CLDR process, but do keep the following in mind:

Tip: The Reports are a great way to validate consistency across related logical groups, e.g. translations of date formats. Use them to proofread your work for consistency.

Tip: The links in the Info Panel will point you to relevant instructions for the entry you’re editing/vetting. Use it if in doubt.
