Developed by educational researchers, Ready4K is an evidence-based family engagement curriculum delivered via text message for children 0-9. Each week, parents and caregivers receive fun facts and easy tips on how to promote their children’s development by building on existing family routines – like pointing out the letters on shampoo bottles during bath time and naming their sounds, counting the number of forks and spoons as you put them away, or making feeling faces in the mirror after you brush your teeth. In a series of randomized controlled trials, this approach has been shown to increase child development by 2 to 3 months over the course of a school year. The Ready4K curriculum covers birth through fourth grade and is available in English, Spanish, and Arabic.. A whole child curriculum, Ready4K now includes COVID-appropriate content. 94% of parents report using the texts every week.
