1970 BCS cohort members' child (multi-age, 2004)

When the Cohort Member (CM) was aged 34, child assessments were conducted with the CM’s children. Each of the CM’s eligible children was asked to complete three exercises designed to measure a range of verbal and numerical abilities. Although dependent on the child’s age and abilities, each set of exercises was expected to take an average of 20 minutes to complete.

Appropriate exercises were used for different age groups:

• Age 3-5 years 11 months:
  • British Ability Scales (BAS)
    • Naming Vocabulary
    • Early Number Concepts
  • Copying Designs Test (same as used with BCS70 cohort members)
• Age 6-16 years 11 months:
  • BAS
    • Word Reading
    • Number Skills
    • Spelling
