This study investigated the effectiveness of the Home Instruction for Parents of Preschool Youngsters (HIPPY) program on school readiness. The HIPPY program uses home-based instruction to aid parents in teaching their children school readiness skills. The curriculum in this program includes literacy, math, and social skills. Texas Assessment of Knowledge and Skills assesses the academic achievement of students in different grade levels and in various subject areas. The chi square test revealed that the children in the HIPPY program were more likely to have higher passing rates on the first administration of TAKS Reading, Math and Science sections compared to non-participants. The implementation of early intervention and parental involvement programs such as HIPPY helps to facilitate students‟ success.
