Abstract:      Addressing and activating Learning styles represent one of the most debated issues in both learning and teaching English to young learners as a foreign language. Identifying Learning style is a significant factor for EFL young learners' academic achievement and attitudes. It has a vital role in the life of learners. If learners acknowledge their learning styles, they will be able to integrate it into their learning process. Consequently, the learning process will be simpler, quicker, and more beneficial. Therefore, this study aimed at designing a valid and reliable inventory test to identify learners' learning styles. The sample consisted of (80) students from Azza- Zydan Experimental School, Fayoum governorate, Egypt. The content validity of items in the test was verified by experts in the field of the curricula and EFL instruction. Besides, the statistical package for social sciences (SPSS) was used for analyzing the data obtained, the total correlation of the items was determined, and correlation measurements between subtitles and the total points of the scale were also performed. Also, Cronbach's Alpha coefficient test was applied to determine the test reliability. To define the internal consistency and reliability of the test, The Alpha test focused on subtitles, in particular. After these analyses, the results indicated that the learning styles inventory was accepted as a valid and reliable measurement tool.                                              Keywords: Learning styles, Inventory, young learners
