Migrant Children Moved Under Cover of Darkness to a Texas Tent City - The New York Times

The roughly 100 shelters that have, until now, been the main location for housing detained migrant children are licensed and monitored by state child welfare authorities, who impose requirements on safety and education as well as staff hiring and training.

The tent city in Tornillo, on the other hand, is unregulated, except for guidelines created by the Department of Health and Human Services. For example, schooling is not required there, as it is in regular migrant children shelters.
