Who we are and what we do

The Assessors' Association Of Pennsylvania was founded in 1948 by a group of county assessors with the intent of promoting more education and professionalism. Today, the AAP has grown to become a leading association offering a wide variety of services for county assessors.

The AAP Mission is to:

  • improve assessment practices in the Commonwealth of Pennsylvania
  • provide for the collection, distribution, and exchange of information relating to the field of assessing among its members
  • improve public relations
  • inform members of legislation intended to improve assessment functions
  • cooperate with other interested agencies in the promotion of the objectives of this Association
  • encourage a fair and just distribution of the tax burden
