Developmental Level Competencies

The Developmental Level interpretive competencies build off of the Entry Level competencies, which are recommended prerequisites. Conducted Activities, Demonstrations & Illustrated Programs, and Curriculum-based Programs build directly from Foundations & the Interpretive Talk. Informal Visitor Contacts are woven throughout the formal programs and park operations in many ways – pre and post program conversations, in-between stops on a guided tour, visitor centers or while roving the resource or a campground before a program and any other time interpreters may interact with visitors outside their programs. Interpretive Writing is directly connected to the principles and processes found in both Foundations and the Interpretive Talk.


Click on the list to the left to see the description and standard for each Developmental Level competency. Those indicated as "benchmark" are core competencies.

Note: A key role of the Interpretive Development Program is to facilitate periodic review and updating of the competencies and related learning resources. Some core competencies have been recently revised, or are awaiting revision, accounting for the different formats of some pages and resources in this website. And, under the new I&E Academy structure, many more competencies await definition and description.
