Behavior Intervention Monitoring Assessment System 2 (BIMAS-2™)

Behavior Intervention Monitoring Assessment System 2 (BIMAS-2™)

The Behavior Intervention Monitoring Assessment System (BIMAS-2™) is a measure of social, emotional and behavioral functioning in children and adolescents ages 5 to 18 years.  The BIMAS Standard Form includes 34 change-sensitive items that are used for universal screening of behavior concerns and for assessing and monitoring the progress of behavior and mental health related interventions.  The BIMAS items were developed based on over 10 years of research and a scientific model for selecting items that are sensitive to change called Intervention Item Selection Rules (IISRs; Meier, 1997, 1998, 2000, 2004). It is the only commercially available measure comprised of items with demonstrated change sensitivity based on the IISRs model and the only measure build from this perspective in mind from the grounds up.


  1. Universal Screening – By comparing each student’s scores on the BIMAS to a nationally representative normative group, the BIMAS Standard can be employed as a brief screening device to detect students in need of further assessment and to identify their respective areas of need.

  2. Student Monitoring – To provide feedback about the progress of the individual student or groups in intervention programs.

  3. Program Evaluation – To assess changes in behavioral concerns and adaptive skills in a group of students receiving psychosocial interventions (e.g. school-based mental health and special education programs provided on an individual or group basis.
The BIMAS is comprised of standard scales (BIMAS Standard) which can be used as a screening device, to collect baseline data at the beginning of intervention, and for periodical progress monitoring. The BIMAS also is comprised of a pool of items that can be used to develop customized behavioral intervention goals for frequent monitoring (BIMAS Flex).
