The paper reports on the evaluation of Project ESPIRIT (Educational System in Parenting for the Retarded with Infants and Toddlers), a home based program for normal children of retarded mothers. Research problems are cited, such as instability of the experimental group. Preliminary results of analysis of four treatment variables and the criterion measure, the Bayley Scales of Infant Development (BSID), indicated that the BSID for seven project infants remained at or above the statistical average of the test for all three administrations. In addition, investigation of time utilization indicated a steady improvement in how available project and client time was used. (CL)
