Course Description

The Certified Interpretive Guide program from the National Association for Interpretation (NAI) is designed for anyone who delivers interpretive programs to the public. It combines both the theoretical foundations of the profession with practical skills in delivering quality interpretive programming to visitors. Participants have two options:

Option one: take the course without obtaining certification. 

Option two: take the course and add certification as a Certified Interpretive Guide (CIG). You will pay an additional fee for certification and you must complete an open book Core Literature Review exam. The CIG lasts four years and comes with a complimentary one year membership. If you are already a member of NAI, your complimentary membership will be added onto the end of your current membership.

This 32-hour course includes:

  • history, definition, and principles of interpretation
  • making your programs purposeful, enjoyable, relevant, organized, and thematic
  • using tangible objects to connect audiences to intangible ideas and universal concepts in interpretive programs
  • presentation and communication skills
  • certification requirements (50-question literature review; program outline; 10-minute presentation)
  • all materials, workbook, and CIG course textbook
