While there’s not a required certification that you need to work in a daycare, there are a few things that childcare facilities look for in employees and some industry credentials that can help you stand out. Before being hired at a daycare or preschool, you’ll need to pass a criminal background check and most states may also require that you obtain the appropriate clearances from federal or state child protective agencies. Most employers will cover the cost of obtaining these background checks and clearances, though some may ask you to pay for them yourself and will reimburse you after you’ve been cleared.
