Basically, there are two reasons.:
Daycare availability: usually from 6 am to 6 pm. If a mom works full-time to pay the bills, there is no evening care for night classes. Online classes are also a challenge to complete in the evening when the child is home.
The system is set against them. If there is a father paying child support, he only has to pay half of the daycare expense while the mother is working. Any time mom spends in class and the child is in daycare does not get calculated into the equation.
That means, she would have to pay for school, pay 100% of the cost for daycare, during that time AND lose the wages she would have made working.
Hope for Single Moms provides assistance by seeking to remove these carriers to a career education. Included in our support services are financial assistance for housing and daycare and evening study rooms with childcare.
