The IFS SCALE is being used by clinicians in private and institutional settings around the world to assess the internal systems of their clients. It is generally used as a pre-test/post-test evaluative tool.

The results can give the clinician an overview of the basic dynamics of the internal system:

1) the degree of Self-leadership relative to the most commonly found types of Parts,

2) the types of Managers or Firefighters that predominate in the system,

3) the presence of potentially self-harming Parts,

4) the degree of change (when used as a pre- and post-test).

Method: Clinicians generally ask the client to take the test online via this website. There is a fee of $9.99 payable through PayPal or by credit card. Results can be saved to the desktop or emailed to the client or clinician.
