Assessment protocols by age group: which one to use for each child
An overview of the most used protocols in autism intervention and their target age ranges, to help choose the right instrument for the child.
There is no single protocol for every child. Age, current repertoire, and the clinical question define which instrument is most helpful. Many clinics combine a curriculum instrument, which guides the plan, with another for development or adaptive behavior, which provides a broader view.
Overview by age group
| Protocol | Target range | Purpose |
|---|---|---|
| ESDM (Early Start Denver Model) | 12 to 48 months | Early intervention curriculum by levels and domains |
| VB-MAPP | Milestones from 0 to 48 months development | Verbal behavior, barriers, and transition |
| Portage | 0 to 6 years | Developmental inventory in five areas |
| IDADI | 4 to 72 months | Child development with normative results |
| SPM (home version) | 5 to 12 years | Sensory processing, with T-score by scale |
Other instruments, such as ABLLS-R, PEAK, Socially Savvy, Essential for Living, and PEDI, have target audiences and age ranges defined in their manuals. Consult each manual before choosing.
How to choose
- Young child, start of intervention: a curriculum like the ESDM usually guides the first plan well.
- Focus on language and verbal behavior: the VB-MAPP shows milestones by area and learning barriers.
- Broad developmental view: inventories like Portage and IDADI cover various areas, and IDADI provides normative results.
- Sensory issues: the SPM helps understand sensory processing at home.
Precautions
- Use the age range as a reference, not as an absolute rule: the child's repertoire carries as much weight as their age.
- Always re-administer the same instrument to compare progress.
- Copyright-protected protocols require professional certification.
Protocols in Proaba
Proaba has over 15 digital protocols, including ESDM (1st and 2nd edition), VB-MAPP, ABLLS-R, Portage, IDADI, Socially Savvy, PEAK, Essential for Living, SPM, PROC, and PEDI. Each is administered as a checklist by level and domain, with history and comparison between administrations, and some have their own interpretation: the VB-MAPP milestones grid, the IDADI normative calculation, and the SPM T-score.
