The Level 3 International Foundation Diploma for Higher Education Studies (L3IFDHES) is usually a one-year pre-university qualification that provides students with an entry route to an overseas university. The L3IFDHES prepares students with the essential English language skills, key transferable study skills, cultural knowledge, and chosen specialisms that universities feel bridges the gap between high school and undergraduate study. In January 2023 we offer pathways in business and higher finance. With agreements in place with over 70 universities across the globe, students’ can progress with confidence to a higher education course for further study. Entry Requirements For entry onto the NCC Education Level 3 International Foundation Diploma for Higher Education Studies (L3IFDHES) qualification students must have successfully completed secondary school education. Students must also meet the English language entry requirements of: • IELTS minimum score of 4.5 or above OR • GCE ‘O’ Level English D7 or above Alternatively, a student can take the free NCC Education Higher English Placement Test which is administered by our Accredited Partner Centre’s.
