The Birth to Three Assessment and Intervention - Second Edition (BTAIS-2) provides examiners with an integrated, three-component system for screening, assessing, and intervening with children age birth to 3.
Children identified as delayed can be tested with the Comprehensive Test of Developmental Abilities (CTDA), a criterion-referenced measure built to identify each child's specific strengths and weaknesses, and to guide the preparation of instructional plans. The CTDA was built to assess children in the following areas:
The CTDA Record Forms are used to indicate the child's observed performance on each CTDA subset item.
Examiners will mark 'Observed Behaviour', 'Emerging Behaviour' or 'Not Observed Behaviour'.
