"School readiness" is more than knowing the ABCs. Research shows quality early care builds the full set of skills children need to thrive in kindergarten.

What the research shows

In the NICHD study, children in programs that met more recognized standards — for adult-child ratios, group size and caregiver training — had better school readiness, language comprehension and behavioral adjustment. Quality care gives children a running start.

The five domains of school readiness

DomainWhat it looks like
Language & literacyVocabulary, listening, letter & sound awareness
Early math thinkingCounting, sorting, patterns, shapes
Self-regulationFocusing, waiting, managing big feelings
Social-emotional skillsSharing, friendship, following routines
Physical & motorFine-motor (holding a crayon) & gross-motor

Self-regulation may matter most

Teachers often say the children who thrive in kindergarten aren't those who memorized the most facts — they're the ones who can focus, follow directions and recover from frustration. Quality early care practices these "executive function" skills all day through play and routine.

How quality care builds readiness

From Shadi: So many of our families stay with us until kindergarten — and tell us their children walk in confident, curious and ready to learn. That's the goal.
