The ASEBA is a comprehensive evidence-based assessment system developed through decades of research and practical experience. The ASEBA assesses competencies, adaptive functioning, and behaviour, emotional, and social problems from age 1 1/2 to over 90 years.
There are three forms available for the school-age assessment:
- Child Behavior Checklist (CBCL 6-18)
 - Teacher Report Form (TRF)
 - Youth Self Report Form (YSR 11-18)
 
The following cross-information syndromes were derived from all three forms:
- Anxious/depressed
 - Withdrawn/depressed
 - Somatic complaints
 - Social problems
 - Thought problems
 - Attention problems
 - Rule-breaking behaviour
 - Aggressive behaviour
 
Inattention and hyperactivity-impulsivity subscales are scored from the TRF attention problems syndrome. All forms have the parallel internalising, externalising, and total problem scales and there are six DSM-oriented categories:
- Affective problems
 - Anxiety problems
 - Attention deficit/hyperactivity problems
 - Conduct problems
 - Somatic problems
 - Oppositional defiant problems
