About the Measure
| Domains | Language |
| Subscales | No |
| Target Construct | Oral language: Receptive vocabulary |
| Description | Leading vocabulary assessment for standard English. As no reading is required, BPVS3 can be used to assess language development in non-readers and especially pupils with expressive language impairments. Because no spoken response is required, the assessment may be administered to pupils with autism and other related communication difficulties or those with English as an Additional Language (EAL). |
