Proficiency in English language and how it is measured have become central issues in higher education research as the English language is increasingly used as a medium of instruction and a criterion for admission to education. This study evaluated the English language assessment in the foundation Programme at the Colleges of Applied sciences in Oman. It used thematic analysis in studying 118 documents on language assessment. Three main findings were reported: compatibility between what was taught and what was assessed, inconsistency in implementing assessment criteria, and replication of the General Foundation Programme standards. The implications of the findings on national and international higher education are discussed and recommendations are made.
