Description

The COSS is designed to help the assessor understand how children organise their time, their materials, and their actions to accomplish important tasks at home and at school. The COSS quantifies organisational skills for children aged 8 to 13 years based on ratings from parents, teachers and the child.

How to Use the Assessment

Rating scales are available in parent, teacher and self-report form formats. The COSS scales include Task Planning, Organises Actions, and Memory and Materials Management. An Inconsistency Index is available on all three forms. This index is useful for determining response patterns that may affect results due to careless/random responding.

The self-report form also contains a Positive Impression Index to help identify inaccurate representation of problems by making situations appear better than they really are and has a negative attitude toward the testing process.

Scales and Forms

• Task Planning
• Organisational Behaviour
• Memory and Materials Management

Technical Information

Over 5,000 assessments were collected, including ratings of youth in the general population sample, clinical cases, and those included in the validity studies. The normative sample for the COSS includes ratings from 480 parents, 480 teachers, and 480 youth. The sample was stratified to represent the general U.S. population according to age, gender, and race/ ethnicity (U.S. Bureau of the Census, 2000). The normative sample is also diverse in terms of parental education level and geographic region. Separate norms are available for males and females, in 2-year age intervals (combined gender norms are also available).

Reports

Assessment Reports - Assessment Reports provide information about the child's scores, how they compare to other children and which scales are elevated.

Progress Reports - Progress Reports combine the results of up to four administrations from the same rater to summarise important changes in reported behaviour that have occurred over time.

Comparative Reports - Comparative Reports integrate ratings provided by child, parent and teacher respondents. The results from up to five different raters can be compared to summarise important similarities and differences in the raters' perceptions of the child's behaviour.
