The instrument was developed and researched at the Graduate Program, School of Occupational Therapy, of Hadassah and Hebrew University, Jerusalem, Israel. The DOTCA-Ch (based on the LOTCA) has been adapted for children ages 6-12 years, with an elaborate praxis area. A structured 5-step cueing system was added based on Toglia’s (1994) system in the TCA with her permission. The DOTCA-Ch battery consists of 22 subtests in 5 cognitive areas: orientation, spatial perception, praxis, visuomotor construction (including reaction time and immediate and delayed memory measures) and thinking operations. Each subtest has a base line score, a mediation score and a posttest score. The goals of the assessment are to identify the abilities and disabilities of the child in the different areas, to measure the learning potential and recognize the thinking strategies, through the use of a dynamic assessment. Standards of performance, cutoff scores and frequencies of dynamic scores of typical children are presented in the manual, as well as reliability and validity data related to children with learning disabilities, following brain-injuries and ADHD. Findings show the instrument to differentiate significantly between typical and disabled children. The instrument is available in English and Hebrew.
