About this course
Over the next handful of lessons you will learn what a tree test actually measures, when it earns its place in a project, and how it differs from the other structure studies in Fernpath. We walk through writing findable task wording, trimming a bloated hierarchy down to something testable, and reading the first-click paths your participants leave behind. Bring a sitemap — you will be editing it by the end.
