Scoring: X/0-3 scale, identifies multiple functions
Automated Scoring
Subscale scores calculate automatically as raters complete items. No manual tallying or spreadsheet formulas required.
- Automatic subscale score calculations
- Function ranking with differentiation scores
- Primary and secondary function identification
- Confidence levels (high, moderate, low, undifferentiated)
- Validity assessment for missing or inconsistent items
Multi-Rater Agreement
When multiple informants complete the same assessment, agreement statistics help identify convergent and divergent perspectives.
- Pairwise agreement percentages between raters
- Intraclass correlation coefficient (ICC) with 95% CI
- Function agreement matrix visualization
- Discrepancy flagging when primary functions differ
- Narrative summary of agreement patterns
Standardized administration
Items present in validated order with consistent instructions. Raters complete independently without influence from other responses.
Function ranking reports
Subscale scores rank from highest to lowest with differentiation scores showing how clearly one function stands out from others.
AI-assisted interpretation
Generate narrative summaries that highlight primary functions, note alternative considerations, and suggest direct observation targets.
Clinical documentation
Export PDF reports with scoring summaries, subscale comparisons, and rater agreement data suitable for FBA reports and treatment plans.
What teams gain from standardized indirect assessment
Indirect assessments provide structured informant input that complements direct observation and interview data in the FBA process.
Function hypothesis documentation
Standardized assessment results provide evidence-based support for function hypotheses in FBA reports and treatment plans.
Multi-perspective convergence
When multiple raters agree on function, teams have stronger confidence. When they disagree, the data highlights where to focus observation.
Baseline for treatment planning
Pre-intervention assessment scores establish baselines that can be compared post-intervention to document treatment effectiveness.

Assessment workflow from administration to report
The platform handles scoring and agreement calculations so practitioners can focus on clinical interpretation.
1
Select the assessment
Choose MAS for motivation-based screening, FAST for functional analysis screening, or QABF for detailed function questions.
2
Administer to raters
Assign the assessment to teachers, parents, or therapists. Each rater completes independently with their own observations.
3
Review automated scoring
Subscale scores calculate automatically. Function rankings show primary, secondary, and undifferentiated patterns.
4
Generate reports
Export PDF reports with scoring summaries, multi-rater agreement percentages, and AI-assisted interpretation notes.
Frequently asked questions
Common questions about indirect assessment administration and interpretation.
What indirect assessments are included?
The platform includes three standardized instruments: MAS (Motivation Assessment Scale by Durand & Crimmins), FAST (Functional Analysis Screening Tool by Iwata, DeLeon & Roscoe), and QABF (Questions About Behavioral Function by Matson & Vollmer).
How does multi-rater agreement work?
When multiple raters complete the same assessment, the system calculates pairwise agreement percentages, intraclass correlation (ICC), and flags discrepancies where raters identified different primary functions.
Does automated scoring replace clinical judgment?
No. Automated scoring provides calculations and rankings, but all results should be interpreted by qualified professionals (BCBA, school psychologist, behavior specialist) who consider the broader clinical context.
Can I use these assessments for insurance documentation?
The assessments generate standardized reports suitable for clinical documentation. Check with your specific payer requirements for indirect assessment documentation standards.
Which plans include AI-assisted interpretation?
Professional and higher tiers include AI-assisted interpretation that provides narrative summaries, alternative function considerations, and recommendations for direct observation follow-up.
