The importance of doing well in whatever you do: A commentary on the special section, “Implementation research in early childhood education”

This commentary on the special section, “Implementation research in early childhood education,” discusses 10 major conclusions drawn from implementation research and 7 additional issues needing clarification. Some major conclusions are that: (1) the level of implementation achieved can have a strong influence on program outcomes, (2) implementation is a multi-dimensional construct, (3) adaptation occurs frequently and may improve outcomes, and (4) many factors present across multiple ecological levels can affect the implementation process. Some of the major issues needing attention in future research involve determining what are the best ways to (1) measure the multiple aspects of implementation, (2) evaluate the relative importance of factors affecting implementation, and (3) clarify which participant characteristics may influence the relationship between implementation and different outcomes.
