The interim controls recommended in the assessment will be provided within 60 days of the in-home education. These interim controls include a set of standard interventions that will be provided in all homes and, in addition, a set of site-specific or targeted interventions based on the assessment findings. Six months after the interventions have been implemented, the child’s health and the home will be assessed using the same instruments, procedures, questionnaires, and the same number and type of samples as in the initial assessment will be taken. This will ensure consistency and quality in data gathering.
