What It Measures
Bayley™-4 uses caregiver or parent involvement to optimize input from the child’s natural environment. Age range: 16 days to 42 months. Benefits include: 1.) Uses caregiver responses to support the scoring of certain items. 2.) Determines the need for further in-depth assessment. 3.) Administers one or more domain subtests individually. 4.) Saves significant time through shortened adaptive behavior content from Vineland-3.
Additional Notes
Administration time varies 30-70 minutes.
