This brief focuses on preparing PFS feasibility studies for early childhood programs. The most common way to develop an analytical approach to preparing for PFS feasibility has been to use historical data and an observational perspective to hypothesize on the value of a quality early childhood treatment for an identified group of families/children. Preparing the PFS feasibility study becomes significantly more problematic from a methodological standpoint when the PFS sponsors are considering more than one treatment to be offered in succession to the same group of families. This brief demonstrates how the Difference in Differences (DiD) statistical technique can be extended to PFS programs with successive treatments.
