Most online tools let us pick one or more languages to present to our participants. This usually covers the tool-supplied prompts and UI controls that the tool shows to participants during the tree test.

A single language

If we’re running our test in a single language, then our job is simple:

1. We pick the tool language that we need, to cover the tool prompts and controls.

2. We write our content (tree, tasks, and other text) in that same language.

Several languages

If we’re running our test in several languages, most tools will make us create a separate test for each language.

For each instance of the test:

1. We pick the tool language that we need, to cover the tool prompts and controls.

2. We write our content in that language.

3. We make sure that any revisions we make (e.g. during our pilot testing) are applied to each instance of the test as needed.

4. When it comes to analyzing the results later, we’ll need to manually compare the results between tests.
