Which of the following factors is NOT considered in determining child support modifications?

In New York, child support is determined based on several factors that reflect the needs of the child and the financial capabilities of the parents. The assessment for modifications of child support typically considers changes in income, health care needs, and cost of living, among other relevant aspects.

The child's academic performance, while important for overall development and potentially impacting other aspects of parenting, is not a direct factor that influences the calculation of child support modifications. Child support is primarily focused on the financial needs of the child and the resources available from the parents, rather than their academic achievements. Hence, while a child's education may be crucial, it does not play a direct role in determining modifications to child support obligations. This is why the child's academic performance is the correct answer, as it is not considered in determining changes to child support.
