District of Columbia 134D refers to the District of Columbia Department of Human Services' subsidy program, which provides financial assistance to low-income families in the District of Columbia. This assistance helps cover the cost of child care, transportation, and other services for families that need support in order to maintain employment, attend school, or participate in job training. There are two types of District of Columbia 134D: the Child Care Subsidy Program and the Transitional Child Care Subsidy Program. The Child Care Subsidy Program provides financial assistance to qualified low-income families to help cover the cost of child care while they are working, attending school, or participating in job training. The Transitional Child Care Subsidy Program provides financial assistance for child care for up to nine months for families transitioning from public assistance to self-sufficiency.
