This chapter deals with specific reference to two assessments for young learners developed by Educational Testing Service (ETS), namely, the TOEFL Junior tests and TOEFL Primary tests. It elaborates on considerations specific to young learners' assessments and describes the experience of using the Common European Framework of Reference (CEFR) with the ETS assessments developed for young English is a foreign language (EFL) learners. The main purpose of the CEFR is to provide a common basis for the elaboration of language syllabuses, examinations, and textbooks by describing in a comprehensive way what language learners have to learn to do in order to use a language effectively for communication. In addition to facilitating the interpretation of scores for the different sections, the CEFR has also been employed to facilitate the interpretation of the overall score levels, first for the TOEFL Junior Comprehensive test and then for TOEFL Junior Standard test.
