About the Motivation Assessment Scale


The Motivation Assessment Scale (MAS) is designed to help with a language impaired person’s problem behaviors. An understanding of a person’s motivations becomes a guide for interventions, such as restructuring the environment or teaching that person skills for fulfilling personal needs in a more effective and productive way. The emphasis is on understanding, respect, and helping a person successfully negotiate their environment.

Benefits of using the MAS:

  • Allows you to respond effectively to behavior

  • Quickly assesses motivation, i.e., the function of a problem behavior

  • Improves positive behavioral interventions

  • The MAS is research-based, tested, and validated

  • Can easily be administered in educational and institutional settings

  • Has been used by psychologists and teachers since 1988

​Why Motivation Assessment Scale Software?​​


For best results, the authors recommend administering several scales (to multiple raters and/or in multiple settings) to evaluate a single problem behavior. Software versions of the MAS provide quick professional assistance in combining and analyzing scale results, assistance in creating reports, a convenient way to store data, and other features.​
