Play and Learning Strategies (PALS) Evidence of Model Effectiveness

PALS Infant meets the criteria established by the Department of Health and Human Services (HHS) for an “evidence-based early childhood home visiting service delivery model” for the general population, but does not meet the criteria for tribal populations because there are no high- or moderate-rated effectiveness studies of the model as implemented with a tribal population.

PALS Toddler/Preschooler and the combination of PALS Infant + Toddler/Preschooler do not meet the HHS  criteria for the general population or for tribal populations because the findings from high- or moderate-rated effectiveness studies of those model versions do not meet all required criteria.
