CAS Cognitive Assessment System
CAS answers a different question from an IQ test: not "how able is this child?" but "how does this child think?"
The four PASS processes
| Process | What it measures | How weakness shows |
|---|---|---|
| Planning | Generating and monitoring strategy | Starting without a plan, not noticing errors, disorganised work |
| Attention | Selective and sustained attention | Distractibility, missed instructions, fatigue on long tasks |
| Simultaneous | Grasping relationships as a whole | Reading comprehension, geometry, problem construction |
| Successive | Processing information in sequence | Reading and spelling difficulty, losing multi-step instructions |
Because CAS is relatively independent of vocabulary and school learning, it is particularly informative for bilingual children and where schooling has been interrupted. It is administered individually to children aged 5–17.
