The only advantage of using the ASQ-3 Materials Kit available from Brookes Publishing is the convenience factor. It is perfectly acceptable to assemble the materials needed for an ASQ-3 screening using the materials in a child's natural environment, such as their home or child care center. In fact, it is important to note that children respond best to items they are already familiar with, such as items from their home. It is also important that toys and materials be relevant to the child's cultural practices.

For programs interested in assembling the materials needed, a list of materials needed for each age interval is available.
