The table below lists all the measures administered to the Target Participant’s School Observer in each study year. An x indicates that the measure was given to both cohorts in a given study year. A number in a cell indicates that a measure was administered just to cohort 1 (1) or to cohort 2 (2). The table can be searched for keywords. The table can also be sorted by columns to find measures given in a specific study year or at a specific age. The items included in the measure are available by selecting the measure name.
