This study aimed at investigating the effectiveness of a suggested program based on explicit systematic phonics instruction on developing word recognition skill among 31 EFL third grade primary pupils at Anwar El Haramein primary school, El Badary, Assiut. In order to fulfill this, the following (basic reading performance test, observation cards) were administered to the experimental group. The study adopted quasi- experimental methodology where the researcher developed the following instruments for research purposes. Data collection process includes both quantitative and qualitative techniques. The data were statistically processed by the arithmetic mean, standard deviations, T- Test for calculating mean differences and its statistical significance, and Eta square equation to compute the effect size of T- Test. The result of the research were analyzed and findings revealed that there was existence of statistically significant differences between the performance means of pupils in the experimental group in the measurement before treatment and their performance  mean after treatment measurement on the performance reading test for the favor of the after treatment measurement.
