eligibility is largely income-based, although each local program includes other eligibility criteria, such as disabilities and services needed by other family members. families must earn less than 100% of the federal poverty level. families may also qualify under a categorical eligibility category—receipt of temporary assistance to needy families (tanf) funds, supplemental security funds, or homeless, as per the mckinney-vento act. up to 10% of any funded program's enrollment can be from higher income families or families experiencing emergency situations. all programs are required to provide services to children with disabilities, who must comprise 10% of their total enrollment. per the head start act (2007), programs may elect to serve families whose income is between 100-130% under certain circumstances. programs must also complete additional reporting requirements if this is appropriate for their community.
