The current ‌study investigated the effect of Using GLM to develop Preparatory Stage Pupils' EFL Reading Skills. The participants of the study comprised 68 pupils randomized from second-year preparatory pupils at Alshahid Mahmoud Elsayed  prep school, Elbagour, Menoufia governorate during the second semester of the 2019– 2020 scholastic year. They were divided into two groups; experimental (34) and control (34). The Generative learning Model was used in teaching the experimental group while the control group received regular instruction. The study adopted the quasi-experimental pre-posttest design. A pre-posttest reading skills test was prepared by the researcher and administered before and after the treatment.  The findings revealed that using Generative Learning Model had a positive effect on developing EFL prep stage pupils' reading skills. Hence, the results seemed to provide adequate evidence to support the hypotheses. The progress occurred in the pupils' reading skills was due to GLM. It is recommended that teachers and curriculum designers pay attention to the importance of Generative learning Model in EFL teaching and learning.
