Course Progression

BEST Preservation Workshops build upon one another, following the natural progression of a historic preservation project. Inquiry courses lead to Documentation & Investigation courses which lead to Treatment courses which in turn lead to Maintenance courses. So:

I → D&I → T → M

This structure identifies major categories that take a project from concept to reality, and from design to implementation. This structure was originally designed and implemented by the Vanishing Treasures Program and has been in use since 2017 offerings.

  • Inquiry: Courses cover the basics of historic preservation and are strongly recommended for all students before taking more advanced courses.
  • Documentation & Investigation: Documentation workshops focus on researching historic resources and recording existing conditions in the field. Investigation workshops teach problem-solving strategies for defining deterioration problems and quantifying their potential impact.
  • Treatment: Workshops cover the construction strategies, condition assessment, treatment, and conservation science of major building materials. Treatment workshops are hands-on and split between the field and the classroom.
  • Maintenance: Workshops introduce students to methods and best practices for continued stewardship of historic resources after preservation, including how to evaluate treatments, write and follow maintenance and lifecycle plans, and bring historic resources into asset management programs.

  • What is the BEST Preservation Workshop Series? The BEST Preservation Workshop Series trains NPS employees at all levels in the preservation of traditionally built historic resources using problem-based and hands-on learning.
