The Ready4K Approach

Our founder, Dr. Benjamin N. York, and colleagues from Stanford University first studied the Ready4K approach during the 2013-14 school year in a randomized controlled trial (RCT) in partnership with the early education department of a large, diverse urban district serving the city’s lowest-income preschool families.
In the research study, one set of parents received a carefully-crafted curriculum with fun FACTS, easy TIPS, and GROWTH activities via text message. These messages focused on how to promote children’s literacy development by building on existing family routines.
The research showed:
- These parents reported engaging in more home literacy activities with their children.
- Teachers reported increased involvement at school among the parents in the treatment group.
Subsequent RCTs showed:
- Outcomes for students were even more wide-ranging when families received a whole child curriculum.
- Receiving messages that were personalized and differentiated to the student were 63% more effective than general messages.
The Ready4K content team uses a continuous improvement cycle to ensure families and schools receive the highest quality experience possible.
Ready4K meets the highest standards for evidence-based programs
By leveraging the Ready4K approach our programs meet the most rigorous Head Start and ESSA Tier 1 standards. Here’s what the research has shown:

2-3 Months Literacy Gains
